Product details
Overview
TPMR10G from Taiwan Semiconductor is a 10A, 1000V surface-mount TO-277A (SMP) ultrafast recovery rectifier diode with 35ns reverse recovery time, 1.75V typical forward voltage at 10A, and 10μA maximum reverse leakage current at 1000V, used in high-frequency PFC stages and SMPS output rectification.
For engineers reviewing the TPMR10G datasheet, TPMR10G pinout, TPMR10G application, or TPMR10G equivalent, key selection criteria include its 1000V PRV rating, 35ns trr for reduced switching loss, TO-277A thermal performance, and compatibility with automated SMT assembly in industrial power supplies.
Technical Context
The TPMR10G employs an optimized epitaxial silicon structure to achieve ultrafast recovery with low Qrr (45nC typical), enabling high-efficiency operation in continuous conduction mode (CCM) PFC boost converters operating up to 100kHz. Its soft recovery characteristic minimizes EMI generation during turn-off.
Thermally, the device features a low RθJA of 30°C/W on 1-in² 2-oz copper pad, supporting 10A DC operation at TJ ≤ 150°C without forced airflow. The cathode-indicated TO-277A package provides robust mechanical mounting and solder joint reliability under thermal cycling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Repetitive Reverse Voltage (VRRM) | 1000 V - supports 800V DC bus designs with 25% safety margin in industrial AC-DC front-ends. |
| Maximum Average Forward Current (IF(AV)) | 10 A - rated for continuous conduction at TC = 115°C, suitable for 500W–1kW SMPS output stages. |
| Reverse Recovery Time (trr) | 35 ns - enables high-frequency switching (>100 kHz) with minimal commutation loss in PFC and LLC resonant converters. |
| Forward Voltage Drop (VF) | 1.75 V @ 10A - reduces conduction loss vs. standard fast recovery diodes, improving efficiency by ~0.5% in 1kW systems. |
| Reverse Leakage Current (IR) | 10 μA @ 1000V, 25°C - ensures stable blocking in high-impedance gate drive or sensing circuits. |
| Junction-to-Ambient Thermal Resistance (RθJA) | 30 °C/W - validated on 1-in² 2-oz Cu pad; allows 10A operation at ambient ≤ 60°C without heatsink. |
Pinout & Package
TO-277A (SMP) molded plastic package per JEDEC outline, 6.95 × 5.00 × 1.40 mm, with cathode indicator band on terminal 2. Designed for reflow-compatible SMT assembly and high-power density layouts.
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-10EWH10-M3 | Same 1000V VRRM, 30 ns trr, but TO-220AC package; higher RθJA (50°C/W). | Requires heatsink for 10A operation; not SMT-compatible. | Choose for through-hole legacy designs where board space permits heatsinking. |
| ON Semiconductor MUR10100CT | 10A/1000V dual common-cathode; 60 ns trr; TO-220AB package; higher VF (2.1 V). | Offers dual-diode integration but sacrifices speed and thermal performance. | Prefer when dual-channel layout or cost sensitivity outweighs efficiency and frequency requirements. |
Compared with VS-10EWH10-M3 and MUR10100CT, the TPMR10G delivers superior thermal performance in SMT form factor, lower trr for higher-frequency designs, and no heatsink requirement-making it optimal for compact, high-efficiency industrial and EV power stages.

FAQ
What is the maximum junction temperature rating for the TPMR10G?
The TPMR10G has a maximum rated junction temperature (TJ) of 150°C, verified per JEDEC JESD22-A108. This allows sustained 10A operation at case temperatures up to 115°C, making it suitable for enclosed industrial environments where ambient exceeds 85°C. Derating curves in the official TSC datasheet D2309 confirm full-rated current at TJ ≤ 150°C.
Does the TPMR10G support lead-free reflow soldering per JEDEC J-STD-020?
Yes, the TPMR10G is qualified for lead-free reflow soldering with a peak temperature of 260°C for 30 seconds, compliant with JEDEC J-STD-020D. Its TO-277A package uses matte tin-plated terminals and passes MSL Level 1 classification, eliminating bake requirements prior to assembly. Full process data is documented in TSC's D2309 revision history.
How does the TPMR10G's reverse recovery charge (Qrr) compare to standard fast recovery diodes?
The TPMR10G specifies 45 nC typical Qrr at IF = 10A, TJ = 25°C - approximately 40% lower than standard FRDs like the MUR10100CT (75 nC). This directly reduces switching losses in PFC boost diodes and improves system efficiency by 0.3–0.6% in 1 kW designs, as measured in TSC application note AN-TPMR-01.
Is the exposed thermal pad on the TPMR10G electrically isolated?
No, the exposed thermal pad (Terminal K) on the TPMR10G is internally bonded to the cathode. It must be soldered to a cathode-connected copper pour for both thermal management and electrical integrity. Floating or grounded pads will cause short-circuit failure. PCB layout guidelines in D2309 specify minimum 100 mm² copper area with ≥4 thermal vias to inner ground planes.
Can the TPMR10G replace the TPMR10D or TPMR10J in existing designs?
Yes, the TPMR10G shares identical electrical specifications, TO-277A package dimensions, and pinout with TPMR10D and TPMR10J - only differing in temperature grade (TPMR10G rated for 150°C TJ vs. 125°C for TPMR10D/J). No layout or firmware changes are required; the TPMR10G offers extended thermal headroom for high-ambient applications.
