Product details
Overview
SR40100PTH from Taiwan Semiconductor is a 40A, 100V AEC-Q101-qualified Schottky barrier rectifier in TO-247AD (TO-3P) package, featuring 0.90 V forward voltage at 20 A and 25°C, 400 A surge capability, 1.2 °C/W junction-to-case thermal resistance, and dual-die construction for high-reliability DC/DC converter output rectification.
For engineers reviewing the SR40100PTH datasheet, SR40100PTH pinout, SR40100PTH application, or SR40100PTH equivalent, key selection criteria include peak reverse voltage rating, forward voltage drop at operating current, thermal resistance under forced-air or heatsink mounting, and AEC-Q101 qualification status for automotive-grade power supply designs.
Technical Context
This device implements a dual-die Schottky structure with guard ring overvoltage protection, enabling stable operation up to 100 V repetitive peak reverse voltage (VRRM) and 70 V RMS reverse voltage. Its low VF and high IFSM support high-efficiency, high-current switching applications where conduction loss and transient robustness are critical.
Thermal performance is defined by RθJC = 1.2 °C/W and maximum junction temperature of 150°C, requiring mechanical mounting with ≤1.13 N·m torque. The matte tin-plated leads comply with J-STD-002 solderability and JESD201 Class 2 whisker resistance standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum non-repetitive reverse blocking voltage; defines upper limit for DC bus or output rail voltage in SMPS designs |
| IF | 40 A - Continuous average forward current at case temperature ≤ 125°C; sets baseline conduction capacity for high-power converters |
| IFSM | 400 A - Peak non-repetitive surge current (8.3 ms half-sine); enables robustness against line transients and startup inrush |
| VF | 0.90 V @ 20 A, 25°C - Low conduction loss per diode; directly reduces power dissipation and improves system efficiency |
| RθJC | 1.2 °C/W - Junction-to-case thermal resistance; determines required heatsink size for thermal management at full load |
| TJ(max) | 150°C - Maximum allowable junction temperature; supports extended operation in high-ambient automotive or industrial environments |
| IR | 500 µA @ 100 V, 25°C - Low leakage current; minimizes standby power loss in energy-sensitive applications |

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-40CPH10-M3 | Same 100 V VRRM, 40 A IF, TO-247AC package; VF = 0.87 V @ 20 A, but not AEC-Q101 qualified | Preferred for industrial/commercial SMPS where automotive qualification is unnecessary | Select when cost sensitivity outweighs automotive compliance requirement |
| ON Semiconductor MBR40100CT | 100 V VRRM, 40 A IF, TO-247AC; VF = 0.92 V @ 20 A; AEC-Q101 qualified; dual common-cathode configuration | Identical pinout and function, but uses common-cathode instead of isolated-tab layout | Choose when existing PCB layout accommodates common-cathode footprint and thermal isolation is less critical |
Compared with VS-40CPH10-M3 and MBR40100CT, SR40100PTH offers AEC-Q101 qualification plus an isolated metal tab for flexible heatsink grounding, making it optimal for automotive systems requiring both reliability and layout flexibility in high-current rectification.

FAQ
What is the maximum junction temperature rating for SR40100PTH?
The SR40100PTH has a maximum junction temperature (TJ(max)) of 150°C, verified per AEC-Q101 stress testing. This rating applies under continuous operation with proper heatsinking and case temperature maintained ≤125°C. Operation above this limit risks permanent degradation of the Schottky junction and must be avoided in all designs using SR40100PTH.
Is SR40100PTH pin-compatible with SR40100PT?
Yes, SR40100PTH shares identical TO-247AD (TO-3P) mechanical dimensions, pinout, and terminal configuration with SR40100PT. The only difference is AEC-Q101 qualification - SR40100PTH is qualified, while SR40100PT is not. Both parts use the same anode–cathode–tab terminal assignment and mounting torque specification (≤1.13 N·m) in SR40100PTH designs.
What does the "H" suffix in SR40100PTH signify?
The "H" suffix in SR40100PTH explicitly denotes AEC-Q101 qualification per Revision D. This certification covers high-temperature operating life (HTOL), temperature cycling (TC), high-temperature reverse bias (HTRB), and unbiased highly accelerated stress test (UHAST). It confirms SR40100PTH meets automotive electronic component reliability requirements, unlike non-H variants such as SR40100PT.
How does the guard ring feature improve reliability in SR40100PTH?
The guard ring in SR40100PTH enhances edge termination stability under high dv/dt and overvoltage conditions, preventing localized avalanche breakdown at the silicon periphery. This design feature extends operational lifetime in noisy automotive environments and improves surge tolerance during line transients - a key reliability differentiator confirmed in SR40100PTH AEC-Q101 qualification reports.
Can SR40100PTH be used in surface-mount designs?
No, SR40100PTH is a through-hole TO-247AD (TO-3P) device with three leads designed for vertical mounting and bolt-down heatsinking. It lacks surface-mount terminations or land patterns. Attempting SMT reflow or hand-soldering will damage the internal die attach and compromise thermal performance. SR40100PTH requires mechanical mounting hardware and heatsink interface per its datasheet mechanical specifications.
