Product details
Overview
SRS10100H from Taiwan Semiconductor is a 10A, 100V Schottky barrier rectifier in TO-263AB (D2PAK) package, featuring 0.90V forward voltage at 5A/25°C, 120A surge capability, AEC-Q101 qualification, and guard ring overvoltage protection-used in automotive DC/DC converters and reverse battery protection circuits.
For engineers reviewing the SRS10100H datasheet, SRS10100H pinout, SRS10100H application, or SRS10100H equivalent, key selection criteria include repetitive peak reverse voltage (100 V), junction-to-case thermal resistance (2 °C/W), moisture sensitivity level (J-STD-020 Level 1), and dual-die configuration for high-current freewheeling paths.
Technical Context
The SRS10100H integrates two Schottky die in a single TO-263AB (D2PAK) thermally optimized package, enabling high-efficiency unidirectional conduction with low forward voltage drop and fast switching recovery. Its AEC-Q101 qualification confirms suitability for automotive under-hood environments.
Junction temperature range spans –55°C to +150°C, supported by 2°C/W junction-to-case thermal resistance and matte tin-plated leads compliant with J-STD-002 solderability. Reverse leakage is limited to 100 µA at 25°C and 5 mA at 125°C under rated VR.
Key Specifications

| IF | 10 A - continuous average forward current rating at case temperature ≤ 110°C |
| IFSM | 120 A - non-repetitive surge current handling for 8.3 ms half-sine wave |
| VF | 0.90 V - forward voltage per diode at 5 A and 25°C, directly impacting conduction loss |
| RθJC | 2 °C/W - thermal resistance from junction to case, critical for heatsink sizing |
| TJ max | +150 °C - maximum allowable junction temperature, enabling high-ambient operation |
| MSL | Level 1 - no floor life limitation before reflow, simplifying SMT assembly logistics |

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-10BQ100-M3/45 | Same 100 V VRRM, 10 A IF, but TO-263AB package with 2.5 °C/W RθJC and 1.05 V VF @ 5 A | Higher forward drop increases conduction loss in high-duty-cycle DC/DC; suitable where thermal margin exists | Prefer SRS10100H when minimizing board-level heat generation is critical |
| ON Semiconductor MBR10100CT | 100 V, 10 A dual common-cathode Schottky in TO-220AC; no AEC-Q101 qualification; 0.85 V VF @ 5 A | Lacks automotive qualification and surface-mount compatibility; requires through-hole assembly | Choose SRS10100H for SMT automotive designs requiring AEC-Q101 and D2PAK footprint |
Compared with VS-10BQ100-M3/45 and MBR10100CT, the SRS10100H delivers lower forward voltage (0.90 V vs. 1.05 V/0.85 V trade-off), superior thermal resistance (2 °C/W), and AEC-Q101 compliance in a surface-mount D2PAK-making it optimal for space-constrained, thermally demanding automotive power stages.

FAQ
What is the maximum junction temperature rating for the SRS10100H?
The SRS10100H has a maximum junction temperature (TJ) rating of +150°C, verified per AEC-Q101 stress testing. This enables reliable operation in under-hood automotive environments where ambient temperatures exceed 105°C. The device maintains specified electrical parameters up to this limit when thermal design respects the 2°C/W junction-to-case resistance and proper PCB copper area is provided for the cathode tab.
Is the SRS10100H pin-compatible with other parts in the SRS10xxH series?
Yes-the SRS10100H shares identical TO-263AB (D2PAK) mechanical dimensions, pinout, and terminal configuration with all members of the SRS1020H–SRS10150H family. Anode 1, Anode 2, and common cathode (tab) positions are consistent across the series, allowing board-level voltage scalability without layout changes.
Does the SRS10100H require derating at elevated ambient temperatures?
Yes-per the forward current derating curve, the SRS10100H must be derated linearly above 110°C case temperature, reaching zero allowable average current at 150°C. At 125°C case temperature, the usable IF drops to approximately 6.5 A. Thermal design must account for RθJC = 2°C/W and PCB copper thermal mass to maintain safe junction temperatures.
What is the reverse leakage current specification for the SRS10100H at 125°C?
The SRS10100H specifies a maximum reverse leakage current (IR) of 5 mA per diode at 125°C and rated VRRM (100 V), measured with 30 ms pulse width. This value reflects stable high-temperature blocking behavior essential for automotive reverse-battery and freewheeling applications where leakage-induced power loss must remain bounded.
How does the guard ring feature improve reliability in the SRS10100H?
The guard ring in the SRS10100H provides edge termination that suppresses electric field crowding at the silicon periphery, increasing resistance to avalanche-induced degradation during transient overvoltage events such as load dump or inductive kickback. This structural enhancement extends operational lifetime in automotive power circuits without requiring external clamping components.
