Product details
Overview
SRS20150 from Taiwan Semiconductor is a 20A, 150V Schottky barrier rectifier in TO-263AB (D2PAK) package, designed for high-efficiency DC/DC conversion and SMPS secondary-side rectification. It delivers VF = 1.02 V at IF = 10 A and TJ = 25°C, IR ≤ 100 µA at VR = 150 V and TJ = 25°C, with IFSM = 200 A and TJ(max) = 150°C.
For engineers reviewing the SRS20150 datasheet, SRS20150 pinout, SRS20150 application, or SRS20150 equivalent, key selection criteria include its 150 V reverse voltage rating, low forward voltage at high current, dual-die thermal performance (RθJC = 1.5°C/W), and moisture sensitivity level 1 compliance for automated assembly.
Technical Context
The SRS20150 uses dual Schottky die in a single TO-263AB package to achieve high surge capability (IFSM = 200 A) while maintaining low conduction loss. Its guard ring structure provides overvoltage protection, and the matte tin-plated leads meet J-STD-002 solderability requirements.
Thermal design is enabled by RθJC = 1.5°C/W and maximum junction temperature of +150°C, supporting operation in compact, high-power-density converters. The device is rated for 100% JESD201 Class 2 whisker resistance and UL 94V-0 molding compound.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - Maximum repetitive reverse blocking voltage; defines usable input/output voltage range in flyback or forward converters |
| IF | 20 A - Continuous forward current rating; supports high-output-current 12–48 V DC/DC stages without forced air |
| VF @ 10 A | 1.02 V - Forward voltage drop at rated half-load; directly determines conduction loss (20.4 W at 20 A) |
| IR @ 150 V | ≤100 µA - Reverse leakage at full rated voltage and 25°C; critical for standby power and light-load efficiency |
| IFSM | 200 A - Non-repetitive surge rating; withstands inrush and transient overloads in AC/DC front-ends |
| RθJC | 1.5 °C/W - Junction-to-case thermal resistance; enables direct heatsink mounting for thermal management |
| TJ(max) | +150 °C - Maximum operating junction temperature; allows extended operation in sealed or high-ambient environments |
Pinout & Package
Package: TO-263AB (D2PAK), surface-mount, 3-terminal configuration with anode-cathode-anode layout (dual common-cathode die). Case meets UL 94V-0; terminals are matte tin-plated per J-STD-002.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Left tab) | Anode 1 | Input terminal for first Schottky die; electrically isolated from Pin 3 |
| Pin 2 (Center tab) | Cathode (common) | Shared cathode connection for both dies; primary thermal path to PCB copper pour |
| Pin 3 (Right tab) | Anode 2 | Input terminal for second Schottky die; enables dual-output or interleaved rectification |
Key Features
| Feature | Design Value |
|---|---|
| Dual-die configuration | Enables independent anode routing for dual-output SMPS or interleaved phase rectification without external parallel diodes |
| Guard ring structure | Improves ruggedness against voltage transients and edge breakdown in high-dV/dt applications like PFC stages |
| Moisture sensitivity level 1 | Eliminates bake requirement before reflow; compatible with standard SMT lines without dry-pack handling |
| JESD201 Class 2 whisker resistance | Ensures long-term reliability of tin-plated terminations under thermal cycling and humidity stress |
| Halogen-free per IEC 61249-2-21 | Meets environmental compliance for industrial and telecom equipment targeting RoHS and green manufacturing standards |

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-20CPH15-M3 | Same TO-263AB package, 20 A/150 V, VF = 1.05 V @ 10 A, IR = 120 µA @ 150 V | Marginally higher VF and IR; identical thermal and surge ratings | Acceptable alternative where <3% conduction loss increase is tolerable |
| ON Semiconductor MBR20150CT | TO-220AB package (not surface-mount), dual common-cathode, VF = 1.0 V @ 10 A, IR = 100 µA @ 150 V | Through-hole mounting required; lacks moisture sensitivity level 1 and JESD201 Class 2 compliance | Only suitable for legacy through-hole designs; not drop-in for SMT production |
Compared with VS-20CPH15-M3 and MBR20150CT, the SRS20150 offers superior manufacturability (MSL 1, JESD201 Class 2), identical electrical specs to MBR20150CT except for package, and lower VF than VS-20CPH15-M3-making it optimal for high-volume, thermally constrained SMT power supplies.

FAQ
What is the maximum junction temperature rating for the SRS20150?
The SRS20150 has a maximum junction temperature (TJ(max)) of +150°C, verified per absolute maximum ratings table in the official datasheet. This rating enables reliable operation in enclosed power supplies and industrial environments where ambient temperatures exceed +85°C. Derating curves confirm usable current down to +125°C case temperature.
Does the SRS20150 support automated pick-and-place assembly?
Yes, the SRS20150 supports automated placement per J-STD-020 moisture sensitivity level 1 classification-no baking or dry-pack handling required prior to reflow. Its TO-263AB (D2PAK) footprint and matte tin-plated leads comply with J-STD-002 solderability standards, ensuring consistent placement yield in high-speed SMT lines.
What is the forward voltage of the SRS20150 at 20 A?
The SRS20150 forward voltage is specified at IF = 10 A (VF = 1.02 V); at 20 A, typical VF rises to approximately 1.15 V based on Fig.4 Typical Forward Characteristics curve. This value is derived from the published VI curve at TJ = 25°C and must be derated for higher junction temperatures in actual operation.
Is the SRS20150 halogen-free and RoHS compliant?
Yes, the SRS20150 is halogen-free per IEC 61249-2-21 and RoHS compliant, as explicitly stated in the FEATURES section of the official datasheet. These certifications are confirmed for both the silicon die and the UL 94V-0 molding compound used in the TO-263AB package.
How many terminals does the SRS20150 have, and what is their function?
The SRS20150 has three terminals in TO-263AB (D2PAK) package: two anodes (Pins 1 and 3) and one common cathode (Pin 2). This dual-anode, common-cathode configuration supports independent input paths for dual-output or interleaved converter topologies while sharing thermal and return paths.
