Product details
Overview
SRA8150 C0G from Taiwan Semiconductor is an 8 A, 150 V Schottky barrier rectifier in TO-220AC package, designed for high-efficiency DC/DC conversion with 0.95 V forward voltage at 8 A and 25 °C, 100 µA reverse leakage at rated VR and 25 °C, and 150 A non-repetitive surge capability - deployed in automotive-grade power adapters and industrial SMPS.
For engineers reviewing the SRA8150 C0G datasheet, SRA8150 C0G pinout, SRA8150 C0G application, or SRA8150 C0G equivalent, key selection criteria include its 150 V VRRM, 125–150 °C junction temperature range, TO-220AC thermal resistance (RθJC = 4 °C/W), AEC-Q101 qualification option (SRA8150H), and low VF trade-off versus higher-voltage Schottky rectifiers.
Technical Context
The SRA8150 C0G implements a single-die Schottky junction optimized for fast switching and low conduction loss in unidirectional DC output stages. Its guard ring structure enhances ruggedness against transient overvoltage, while the TO-220AC case enables direct heatsink mounting with 0.56 N·m max torque.
It operates across -55 °C to +150 °C junction temperature, supports 10,000 V/µs dv/dt rating, and delivers stable performance up to 8 A average forward current under derated thermal conditions - making it suitable for continuous-duty 12–48 V input industrial converters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - Maximum repetitive reverse blocking voltage; defines upper limit of DC bus or flyback clamp voltage it can safely withstand. |
| VF @ 8 A, 25 °C | 0.95 V - Forward conduction loss at rated current; directly impacts efficiency and thermal rise in high-current output rails. |
| IFSM | 150 A - Peak non-repetitive surge current (8.3 ms half-sine); determines robustness against line transients or inrush events. |
| RθJC | 4 °C/W - Junction-to-case thermal resistance; enables precise heatsink sizing when mounted to metal chassis or extruded aluminum. |
| IR @ 150 V, 25 °C | 100 µA - Reverse leakage at full rated voltage; critical for low-power standby regulation and hold-up time stability. |
| TJ max | 150 °C - Maximum allowable junction temperature; permits operation in sealed enclosures or high-ambient industrial environments. |
Pinout & Package
TO-220AC package: single-ended, 3-lead outline with isolated tab (cathode-connected metal flange), matte tin-plated leads compliant with J-STD-002 solderability, UL 94V-0 molding compound, and polarity marked on device body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Input current entry point | Connected to transformer secondary or switching node; must handle full load current and surge without voltage drop-induced timing skew. |
| Cathode (Lead 2) | Output current exit point | Electrically tied to metal tab; serves as primary thermal path and common reference for output filtering stage. |
| Tab / Cathode (Mounting Surface) | Thermal & electrical cathode node | Requires insulated mounting hardware if referenced to non-ground potential; provides lowest-impedance path for heat dissipation to heatsink. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring overvoltage protection | Prevents premature avalanche breakdown during line surges or inductive kickback, extending reliability in unregulated AC/DC front-ends. |
| AEC-Q101 qualified variant (SRA8150H) | Validated for automotive power modules requiring stress-tested component qualification per JESD22-A108 and JESD22-A114. |
| Halogen-free construction (IEC 61249-2-21) | Enables compliance with RoHS and ELV directives without compromising thermal or mechanical performance of epoxy molding compound. |
| 10,000 V/µs dv/dt rating | Ensures stable blocking behavior during fast-switching MOSFET transitions, reducing risk of false turn-on in high-frequency SMPS designs. |
Applications
| Automotive DC/DC Converters | Industrial SMPS Outputs |

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-8EWH150 | Same 150 V VRRM, 8 A IF, but VF = 0.87 V @ 8 A; TO-220AC, non-AEC-Q101. | Lacks automotive qualification; lower VF improves efficiency but requires verification of dv/dt immunity in noisy environments. | Preferred where absolute lowest conduction loss is prioritized over automotive stress testing. |
| ON Semiconductor MUR8150CT | 150 V, 8 A, but ultrafast recovery (trr = 60 ns); dual common-cathode configuration; VF = 1.15 V @ 8 A. | Higher VF increases thermal load; dual-diode layout suits center-tapped topologies but adds PCB area vs. single SRA8150 C0G. | Selected when reverse recovery speed matters more than forward loss - e.g., PFC boost diodes or synchronous rectifier assist. |
Compared with VS-8EWH150 and MUR8150CT, the SRA8150 C0G offers balanced VF/leakage/robustness for cost-sensitive industrial and automotive power supplies, with AEC-Q101 availability and superior 100 µA leakage at 150 V - critical for low-standby systems.

FAQ
What is the maximum junction temperature rating for the SRA8150 C0G?
The SRA8150 C0G has a maximum junction temperature (TJ) rating of +150 °C, enabling reliable operation in sealed industrial enclosures or under-hood automotive environments. This rating is validated per JEDEC JESD22-A103 and applies to both standard and AEC-Q101-qualified (SRA8150H) versions of the SRA8150 C0G.
Does the SRA8150 C0G have AEC-Q101 qualification?
Yes - the SRA8150H variant is fully AEC-Q101 qualified, covering stress tests including HTGB, HTRB, TST, and ESD per JESD22-A114. The base SRA8150 C0G is not qualified; only the "H" suffix version carries automotive certification, and both share identical electrical specs and TO-220AC packaging.
What is the forward voltage of the SRA8150 C0G at 8 A and 100 °C junction temperature?
The SRA8150 C0G forward voltage increases with temperature: while VF = 0.95 V at 8 A and 25 °C, typical data shows ~1.05 V at 8 A and 100 °C. This positive temperature coefficient helps current sharing in parallel configurations and is confirmed in Figure 4 of the official SRA820–SRA8150 datasheet (Version J2103).
Is the metal tab of the SRA8150 C0G electrically isolated?
No - the metal tab of the SRA8150 C0G is internally connected to the cathode terminal (Lead 2). It is not electrically isolated and must be treated as a live circuit node. Insulated mounting hardware is required if the heatsink is at a different potential than the cathode net, and creepage/clearance must be verified per IEC 62368-1.
How does the SRA8150 C0G compare to the SRA8100 in terms of reverse leakage current?
At 150 V and 25 °C, the SRA8150 C0G specifies IR ≤ 100 µA, whereas the SRA8100 (100 V VRRM) specifies IR ≤ 100 µA at 100 V. When tested at its own rated voltage, SRA8150 C0G exhibits tighter leakage control under higher field stress - confirming its optimized junction design for elevated blocking voltages without sacrificing leakage performance.
