Product Details
Key Features

SR037 is an inductorless, dual output off-line controller providing up to 1.0W of output power. It does not require any transformers, inductors, or high voltage input capacitors. The input voltage, HVIN, is designed to operate from an unfiltered full wave rectified 120V or 230V AC line. It is designed to control an external N-channel MOSFET or IGBT. When HVIN is less than 45V, the external transistor is turned-on, allowing it to charge an external capacitor connected to VSOURCE. An unregulated DC voltage will develop on VSOURCE. Once HVIN is above 45V, the transistor is turned off. The maximum gate voltage for the external transistor is 24V. The unregulated voltage is approximately 18V. The SR037 also provides a regulated 5.0V.

WARNING! Galvanic isolation is not provided. Dangerous voltages are present when connected to the AC line. It is the responsibility of the designer to assure adequate safeguards are in place to protect the end user from electrical shock.

YG GROUP (YUGUANG INTERNATIONAL(HK)CO.,LTD) supports reliable sourcing through quality controls and compliance documentation. Please confirm product requirements, applicable certifications and supporting documents before ordering.

  • 1. Certification Scope: Quality certifications apply only to the entities, sites and activities listed in valid certificates. Management system certification does not certify each individual product.
  • 2. Product Authenticity: Products must match the agreed manufacturer, part number and condition. Supplier screening and authenticity checks help reduce counterfeit risk.
  • 3. Inspection & Testing: The inspection scope follows product risks and agreed requirements. Additional testing, laboratory arrangements, costs and lead times require written confirmation.
  • 4. Traceability & Documentation: Request conformity certificates, traceability records or test reports before ordering. Document availability, issuer and coverage must be confirmed for the offered goods.
  • 5. Environmental Compliance: RoHS and REACH information is based on applicable manufacturer documentation. Confirm the exact part, declaration date and relevant exemptions before ordering.
  • 6. Handling & Protection: Handling, storage and packaging follow applicable product requirements, including ESD and moisture protection where required. Special handling requirements must be agreed before ordering.

Product FAQ
Purchasing FAQ

What type of component is SR037, and what package does it use?

SR037 is an authentic electronic component manufactured by Microchip, categorized under Power Management ICs. It is supplied in the standard manufacturer-specified package footprint, providing industry-standard mechanical dimensions and terminal configurations for board-level assembly. Full pinout configurations, physical footprint drawings, and rated operating tolerances are documented in the official SR037 datasheet above.

Why is pricing for SR037 available via RFQ rather than a fixed checkout price?

Electronic component spot-market pricing for SR037 fluctuates based on real-time global availability, production date codes, minimum order quantities (MOQ), and packaging formats (e.g., Reel, Tube, Tray). Using an RFQ ensures you receive accurate, real-time volume pricing tied to verified, traceable inventory rather than stale catalog estimates.

How quickly can SR037 be shipped once quoted?

Lead times for SR037 depend on whether stock is dispatched from our central hub or regional franchise partners. Ready-to-ship inventory typically leaves the warehouse within 1–3 business days following quality inspection, while factory-direct or back-ordered allocations are confirmed with an estimated ship date upon RFQ reply.
