Product details
Overview
SR30100PTH from Taiwan Semiconductor is a 30A, 100V AEC-Q101-qualified Schottky barrier rectifier in TO-247AD (TO-3P) package, featuring 0.90 V forward voltage at 15 A and 25°C, 300 A surge capability, and 1.5 °C/W junction-to-case thermal resistance. It serves as a high-efficiency output rectifier in automotive-grade DC/DC converters and industrial SMPS.
For engineers reviewing the SR30100PTH datasheet, SR30100PTH pinout, SR30100PTH application, or SR30100PTH equivalent, key selection criteria include its 100 V repetitive peak reverse voltage, dual-die configuration, AEC-Q101 qualification, low VF at high current, and thermal performance under sustained load conditions.
Technical Context
This device implements a dual-die Schottky structure optimized for low conduction loss and fast switching in unidirectional power conversion stages. Its guard ring design provides overvoltage protection, and the matte tin-plated leads meet J-STD-002 solderability standards with JESD 201 Class 2 whisker resistance.
The SR30100PTH operates with a maximum junction temperature of +150°C and exhibits 500 µA reverse leakage at rated 100 V and 25°C, dropping to 10 mA at 100°C - critical for thermal stability in compact, high-power-density designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - supports input/output rails up to 100 V DC without breakdown |
| IF | 30 A continuous - delivers full-rated output current in TO-247AD without forced cooling |
| IFSM | 300 A (8.3 ms half-sine) - withstands inrush and transient surges in SMPS startup |
| VF | 0.90 V @ 15 A, 25°C - reduces conduction loss by ~30% vs. comparable 100 V Si diodes |
| RθJC | 1.5 °C/W - enables direct heatsink mounting for thermal management in high-power converters |
| TJ max | +150°C - allows operation in under-hood automotive environments and sealed industrial enclosures |
| IR | 500 µA @ 100 V, 25°C - ensures low 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-30CPH10-M3 | Same 100 V VRRM, 30 A IF, TO-247AC package; VF = 0.88 V @ 15 A but no AEC-Q101 qualification | Not approved for automotive under-hood use; suitable for industrial/commercial only | Select when AEC-Q101 is not required and lower VF is prioritized |
| ON Semiconductor MUR30100CTG | 100 V, 30 A, dual common-cathode configuration in TO-220AB; VF = 1.1 V @ 15 A; faster recovery than Schottky but higher loss | Higher conduction loss limits efficiency in high-frequency designs; TO-220AB has higher RθJC (3.0 °C/W) | Select when cost sensitivity outweighs efficiency needs and space constraints allow TO-220 footprint |
Compared with VS-30CPH10-M3 and MUR30100CTG, the SR30100PTH uniquely combines AEC-Q101 qualification, 0.90 V forward voltage, and 1.5 °C/W thermal resistance - making it optimal for thermally constrained automotive and high-efficiency industrial converters where reliability and loss reduction are co-prioritized.

FAQ
What is the maximum junction temperature rating for SR30100PTH?
The SR30100PTH has a maximum junction temperature (TJ) rating of +150°C, validated per AEC-Q101 stress testing. This allows reliable operation in under-hood automotive environments and sealed industrial enclosures where ambient temperatures exceed 85°C. The SR30100PTH maintains specified electrical parameters up to this limit when thermal design accounts for its 1.5 °C/W RθJC.
Is SR30100PTH pin-compatible with other parts in the SR30xxPT family?
Yes, all SR30xxPT and SR30xxPTH variants share identical TO-247AD (TO-3P) mechanical dimensions, terminal layout, and pinout - including SR30100PTH. This enables drop-in replacement across voltage grades (20 V to 150 V) without PCB redesign, provided thermal and electrical margins are verified for the specific VRRM and IF requirements of the target application.
Does SR30100PTH have a built-in guard ring, and what is its function?
Yes, the SR30100PTH incorporates a guard ring structure in its die design. This feature prevents premature edge breakdown under high reverse-bias conditions, particularly at its rated 100 V VRRM. It enhances long-term reliability in electrically noisy systems such as automotive power nets and industrial motor drives where voltage transients are common.
What is the reverse leakage current specification for SR30100PTH at elevated temperature?
At 100°C junction temperature, the SR30100PTH exhibits a maximum reverse leakage current (IR) of 10 mA when biased at its full 100 V VRRM. This value is confirmed in the Electrical Specifications table and impacts standby power loss in always-on systems - a critical parameter for battery-backed or energy-star-compliant designs using the SR30100PTH.
How does the "H" suffix in SR30100PTH denote AEC-Q101 qualification?
The "H" suffix in SR30100PTH explicitly indicates full AEC-Q101 qualification per the ordering information table in the datasheet. This means the SR30100PTH has undergone temperature cycling, highly accelerated life testing, and other stress tests defined in AEC-Q101 Rev D. Unlike standard SR30100PT, the SR30100PTH is certified for automotive powertrain and body electronics applications.
