Product details

Overview

SRS10150H from Taiwan Semiconductor is a 10A, 150V Schottky barrier surface-mount rectifier in TO-263AB (D2PAK) package, featuring 1.00V forward voltage at 5A/25°C, 100µA reverse leakage at rated VR and 120A surge current capability; it serves as a freewheeling or reverse-battery protection diode in automotive DC/DC converters.

For engineers reviewing the SRS10150H datasheet, SRS10150H pinout, SRS10150H application, or SRS10150H equivalent, key selection criteria include its AEC-Q101 qualification, junction-to-case thermal resistance of 2°C/W, dual-die configuration, 150°C maximum junction temperature, and moisture sensitivity level 1 compliance for high-reliability automotive power designs.

Technical Context

This Schottky rectifier uses dual dies in a single TO-263AB package to support high-current, low-loss operation. Its 150V repetitive peak reverse voltage and 100µA reverse current at 25°C enable stable blocking in 12–48V automotive systems with transient overvoltage tolerance.

The device operates up to 150°C junction temperature and delivers 10A average forward current with 2°C/W junction-to-case thermal resistance-enabling compact heatsinking in space-constrained DC/DC converter layouts where thermal management is critical.

Key Specifications

I_F	10 A - Continuous forward current rating defining usable output current in DC/DC converter freewheel paths
I_FSM	120 A - Non-repetitive surge current handling capability during load dump or inrush events
V_F @ 5A, 25°C	1.00 V - Low conduction loss enabling >92% efficiency in 12V→5V buck converters at full load
R_θJC	2 °C/W - Enables direct thermal coupling to PCB copper or heatsink for reliable 10A operation at 150°C TJ
T_J max	150 °C - Extended junction temperature rating supporting under-hood automotive placement without derating
MSL	Level 1 - No floor life limitation or bake requirement before reflow, simplifying SMT assembly

Pinout & Package

TO-263AB (D2PAK) package with three terminals: Anode (pin 1), Cathode (pin 2), and exposed thermal pad (pin 3, electrically connected to cathode). Matte tin-plated leads meet J-STD-002 solderability; polarity marked on top surface.

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-10EWH15-M3	Same 150V V_RRM, 10A I_F, but TO-252 (DPAK); R_θJC = 3.5°C/W vs. 2°C/W	Lower thermal performance requires larger copper area or heatsink for same 10A load	Prefer SRS10150H where board space allows TO-263AB and thermal margin is tight
ON Semiconductor SB10150T3G	Identical specs but TO-220AC package; no MSL Level 1 rating; lead finish differs	Not suitable for automated SMT lines requiring moisture-safe reflow	Choose SRS10150H for automotive SMT production with AEC-Q101 and MSL-1 compliance

FAQ

What is the maximum junction temperature rating for the SRS10150H?

The SRS10150H has a maximum junction temperature (T_J) rating of +150°C, verified per AEC-Q101 stress testing. This allows operation in high-ambient environments such as engine compartments without derating, provided thermal design meets the 2°C/W junction-to-case resistance specification. The SRS10150H maintains stable V_F and leakage performance up to this limit.

Is the SRS10150H suitable for automated SMT assembly?

Yes, the SRS10150H is fully compatible with automated surface-mount assembly. It carries Moisture Sensitivity Level 1 (MSL-1) per J-STD-020, meaning no floor life limitation or pre-bake is required before reflow. Its TO-263AB (D2PAK) package and matte tin-plated leads ensure reliable solder joint formation using standard lead-free reflow profiles.

Does the SRS10150H have AEC-Q101 qualification?

Yes, the SRS10150H is explicitly AEC-Q101 qualified, as confirmed in the official Taiwan Semiconductor datasheet revision A2103. This qualification covers stress tests including high-temperature reverse bias (HTRB), temperature cycling, and unbiased highly accelerated stress testing (uHAST), validating its suitability for automotive power applications.

What is the forward voltage of the SRS10150H at 5A and 25°C?

The forward voltage (V_F) of the SRS10150H is 1.00 V under conditions of 5A forward current and 25°C junction temperature, as specified in the Electrical Specifications table. This value reflects typical conduction loss per diode in the dual-die configuration and directly impacts system efficiency in high-current DC/DC converter freewheel paths.

How does the guard ring feature benefit the SRS10150H in automotive applications?

The guard ring in the SRS10150H provides edge termination that suppresses localized electric field crowding at the silicon periphery. This improves V_RRM consistency and prevents premature avalanche breakdown during load-dump transients or cold-cranking events-critical for robust reverse-battery protection and freewheeling functions in automotive 12V/24V systems.
