Product details
Overview
TPMR10GH from Taiwan Semiconductor is a 10A, 100V surface-mount Schottky barrier rectifier in TO-277 package, featuring low forward voltage (VF = 0.82V @ 10A), fast recovery (trr < 35ns), and operating junction temperature up to 175°C. It serves as primary output rectifier in high-efficiency AC/DC adapters and DC/DC converters for telecom power supplies.
For engineers reviewing the TPMR10GH datasheet, TPMR10GH pinout, TPMR10GH application, or TPMR10GH equivalent, key selection criteria include VF vs. thermal derating at 125°C, surge current capability (IFSM = 150A), and TO-277 mechanical compatibility with automated SMT placement.
Technical Context
The TPMR10GH uses platinum-doped silicon epitaxial construction to achieve low VF and soft reverse recovery, minimizing EMI in high-frequency switching topologies. Its unidirectional conduction path supports continuous forward current up to 10A with thermal resistance (RθJA) of 40°C/W on 1-inch² 2-oz copper pad.
Designed for operation at switching frequencies ≥100kHz, the device exhibits stable VF across -40°C to +175°C and maintains reverse leakage (IR ≤ 1mA @ 100V, TJ = 125°C) without thermal runaway under sustained load conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max Repetitive Reverse Voltage (VRRM) | 100 V - Withstands transient surges up to 100V without breakdown in flyback or LLC resonant converter secondary side. |
| Forward Current (IF(AV)) | 10 A - Continuous DC output current rating at TC = 115°C; requires heatsinking above 5A at ambient >60°C. |
| Forward Voltage (VF) | 0.82 V @ 10A, TJ = 25°C - Reduces conduction loss by ~18% vs. standard 10A Si diodes, improving efficiency in 12V/5V POL converters. |
| Reverse Recovery Time (trr) | <35 ns - Enables use in 300–500kHz SMPS without snubber circuits; measured at IF = 1A, di/dt = 100A/μs. |
| Peak Forward Surge Current (IFSM) | 150 A - Survives single half-sine wave (8.3ms) inrush events during cold-start of industrial power modules. |
| Junction Temperature Range (TJ) | -40°C to +175°C - Supports operation in under-hood automotive DC/DC or sealed industrial enclosures without forced air. |
Pinout & Package
TO-277 molded plastic package (JEDEC TO-277 Issue A), 3-terminal surface-mount outline with cathode indicator marking. Dimensions: 6.95 × 5.00 × 1.40 mm (L × W × H), 2.10 mm terminal pitch, 1.05 mm seating plane height.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 (Anode) | Input current entry point | Connected to transformer secondary or switch node; must be routed with low-inductance trace to minimize ringing. |
| Terminal 2 (Cathode) | Output current exit point | Feeds bulk capacitor or downstream regulator; requires thermal pad connection to PCB copper for RθJA reduction. |
| Terminal K (Cathode Tab) | Primary heat dissipation path | Exposed metal tab soldered to thermal pad; accounts for >70% of total heat transfer in TO-277 package. |
Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage drop | VF = 0.82V @ 10A enables ≥0.5% system efficiency gain over comparable 100V Schottkys in 48V input telecom PSUs. |
| High surge current rating | IFSM = 150A allows direct replacement of older 10A rectifiers without redesigning input fuse or layout. |
| Extended temperature operation | Rated to TJ = 175°C supports compact designs where airflow is restricted, such as DIN-rail mounted PLC power supplies. |
| Soft reverse recovery | Trr < 35ns with minimal tail current reduces EMI filter component count in Class B conducted emissions compliance. |
Applications
| Telecom AC/DC Adapter | Industrial DC/DC Converter |
|---|---|
Use Scenario: 48V input, 12V/10A output isolated flyback converter in remote radio unit power supply. IC Role / Device Role / Timing Role: Secondary-side synchronous rectifier replacement; conducts during transformer demagnetization phase.

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 | VF = 0.75V @ 10A (lower), but IF(AV) rated only to 115°C TJ; RθJA = 45°C/W. | Requires larger thermal pad or lower ambient for same 10A load; unsuitable for 175°C ambient environments. | Select when lowest possible VF dominates over max temperature rating. |
| ON Semiconductor MBR10100CT | Dual-diode configuration in TO-220AC; VF = 0.85V @ 10A; discrete anode/cathode pins vs. TO-277's integrated tab. | Through-hole mounting only; incompatible with SMT production; higher profile limits board stacking. | Select only for legacy through-hole designs or prototyping with breadboard compatibility. |
Compared with VS-10BQ100-M3 and MBR10100CT, the TPMR10GH uniquely balances ultra-low VF, SMT manufacturability, and 175°C operation-making it optimal for space-constrained, thermally aggressive applications like 5G base station power modules.

FAQ
What is the maximum junction temperature rating for TPMR10GH?
The TPMR10GH is rated for continuous operation up to 175°C junction temperature, verified per JEDEC JESD22-A108 stress testing. This enables deployment in sealed enclosures or high-ambient environments where conventional 150°C-rated Schottkys would require derating or forced cooling. The TPMR10GH maintains stable VF and IR performance across this full range.
Does TPMR10GH support automated optical inspection (AOI) after reflow?
Yes, the TPMR10GH's TO-277 package features consistent marking contrast (laser-etched YWF code), flat coplanar terminals, and defined cathode indicator geometry-enabling reliable AOI detection per IPC-A-610 Class 2 standards. Its 1.05 mm seating plane tolerance ensures uniform solder joint height for machine vision alignment.
Can TPMR10GH replace older 10A Schottky rectifiers in existing designs?
In most cases yes-TPMR10GH shares identical TO-277 footprint and thermal pad layout with industry-standard equivalents. Its lower VF and higher IFSM improve margin in legacy 10A designs, though thermal simulation should confirm RθJA compliance when replacing parts with different thermal pad metallization or solder mask openings.
What is the reverse leakage current specification for TPMR10GH at elevated temperature?
At 100V reverse bias and TJ = 125°C, TPMR10GH specifies IR ≤ 1.0 mA (max), measured per MIL-STD-750 Method 3010. This low leakage preserves efficiency in high-temperature operation and prevents unintended gate drive coupling in synchronous rectifier configurations using external MOSFETs.
Is TPMR10GH RoHS and REACH compliant?
Yes, TPMR10GH complies with RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, including exemption 7a for lead in high-melting-temperature solder. Certificate of Compliance and material declarations are available upon request for TPMR10GH from Aetrix Electronics' technical documentation portal.
