Product details
Overview
SR506 A0G from Taiwan Semiconductor is a 5A, 60V Schottky barrier rectifier in DO-201AD package, featuring 0.70V max forward voltage at 5A and 500µA max reverse leakage at 25°C. It delivers high efficiency in DC-DC converters and AC-DC adapters with 120A surge capability and 10,000 V/µs dv/dt rating.
For engineers reviewing the SR506 A0G datasheet, SR506 A0G pinout, SR506 A0G application, or SR506 A0G equivalent, key selection criteria include its 60V VRRM rating, thermal resistance (RθJA = 35°C/W), AEC-Q101 qualification option (via H-suffix variants), and DO-201AD mechanical compatibility with standard through-hole power rectifier footprints.
Technical Context
This single-die Schottky rectifier operates with junction temperatures up to +125°C (standard) or +150°C (H-qualified variants), using pure tin-plated leads compliant with J-STD-002 solderability. Its guard ring structure provides overvoltage protection while maintaining low conduction loss.
The device exhibits 6°C/W junction-to-case thermal resistance and supports 8.3ms half-sine surge currents up to 120A. Reverse leakage rises to 10mA at 100°C - a critical design parameter for high-temperature SMPS hold-up and standby circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - Maximum repetitive reverse voltage; defines safe blocking range in 48V-output DC-DC stages |
| IF | 5 A - Continuous forward current; sets minimum heatsinking requirement at full load |
| VF (max) | 0.70 V @ 5A, 25°C - Directly determines conduction loss (3.5W at full load) and thermal budget |
| IR (max) | 500 µA @ 60V, 25°C - Low leakage enables stable no-load regulation in adapter standby mode |
| IFSM | 120 A - Withstands inrush surges during cold-start of industrial power supplies |
| RθJA | 35 °C/W - Enables natural-convection operation up to ~2.5W dissipation without forced airflow |
| dv/dt | 10,000 V/µs - Resists false turn-on in high-frequency switching nodes with fast edge rates |
Pinout & Package
DO-201AD package: axial-leaded, epoxy-molded case with cathode band marking; 1.10g weight; UL 94V-0 rated molding compound; polarity indicated by cathode band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Input current terminal | Connected to input rail (e.g., transformer secondary or boost output); must handle full 5A RMS and 120A surge |
| Cathode | Output current terminal | Feeds output filter capacitor; low VF minimizes voltage drop into downstream regulation stage |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring structure | Prevents premature avalanche breakdown under transient overvoltage, improving reliability in unregulated input stages |
| Low VF (0.70V max) | Reduces conduction loss by >30% vs. comparable PN rectifiers, directly increasing converter efficiency at 5A load |
| 120A IFSM | Supports robust cold-start behavior in 100W+ adapters without derating or parallel devices |
| J-STD-002 solderable leads | Ensures reliable through-hole reflow or wave soldering without lead finish degradation |
| RoHS & halogen-free | Meets IEC 61249-2-21 for environmentally constrained industrial and automotive supply chains |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-50SQ060 | Same 60V VRRM, 5A IF, but TO-220AC package (higher RθJA = 50°C/W) | Requires heatsink above ~1.5W; unsuitable for space-constrained DO-201AD layouts | Select when higher surge margin (150A IFSM) justifies larger footprint and thermal management overhead |
| ON Semiconductor SB560 | 60V VRRM, 5A IF, DO-201AD, but 0.72V VF (typ) and 1000µA IR at 25°C | Higher conduction loss and leakage reduce efficiency in low-power standby modes | Select only if dual-sourcing requires ON Semi second-source with identical mechanical fit |
Compared with VS-50SQ060 and SB560, SR506 A0G offers the lowest VF among DO-201AD 60V/5A Schottkys (0.70V max), best-in-class 500µA leakage at 25°C, and direct compatibility with existing axial-leaded board footprints - making it optimal for thermally constrained, high-efficiency adapter and DC-DC designs.

FAQ
What is the maximum junction temperature rating for SR506 A0G?
The SR506 A0G has a maximum junction temperature (TJ) of +125°C under standard qualification. This rating applies to all non-H-suffix variants in the SR502–SR520 series. The device can operate continuously within this limit provided thermal design maintains junction temperature below threshold under worst-case load and ambient conditions. SR506 A0G does not carry AEC-Q101 qualification; that requires the SR506H A0G variant with +150°C TJ rating.
Is SR506 A0G pin-compatible with other parts in the SR502–SR520 series?
Yes, SR506 A0G shares identical DO-201AD package dimensions, anode/cathode terminal configuration, and mechanical footprint with all members of the SR502–SR520 series. Voltage ratings differ across the family (e.g., SR502 = 20V, SR509 = 90V), but physical mounting, soldering, and PCB layout are fully interchangeable. No board redesign is needed when substituting within the series for voltage adjustment.
What does the 'A0G' suffix mean in SR506 A0G?
The 'A0G' suffix in SR506 A0G indicates packaging format and environmental compliance: 'A0' denotes ammo box packaging (500 units per box), and 'G' signifies halogen-free molding compound per IEC 61249-2-21. This suffix does not imply AEC-Q101 qualification - that requires the 'H' prefix (e.g., SR506H A0G). All SR506 A0G units are RoHS-compliant and J-STD-002 solderable.
How does SR506 A0G's forward voltage compare to SR505 A0G and SR509 A0G?
SR506 A0G has a maximum forward voltage (VF) of 0.70V at 5A and 25°C - identical to SR505 A0G and lower than SR509 A0G (0.85V max). This reflects the family's voltage-dependent VF grading: lower-voltage variants (SR502–SR506) share tighter VF specs, while higher-voltage types (SR509–SR520) trade some conduction loss for increased blocking capability. Designers selecting SR506 A0G gain optimal VF for 60V-class applications.
Can SR506 A0G be used in automotive applications?
SR506 A0G itself is not AEC-Q101 qualified; however, the functionally identical SR506H A0G variant meets AEC-Q101 requirements and is approved for automotive power systems. For non-automotive industrial or consumer use - such as telecom power shelves or USB-C PD adapters - SR506 A0G is fully suitable. Always verify qualification status via part number suffix: 'H' = AEC-Q101, no 'H' = standard industrial grade.
