Product details
Overview
TPMR10DH from Taiwan Semiconductor is a 10A, 1000V surface-mount ultrafast recovery rectifier diode in TO-277 package, featuring 35ns reverse recovery time (trr), 1.85V forward voltage (VF) at 10A, and 100µA maximum reverse leakage current (IR) at 1000V, used in high-frequency PFC stages and SMPS output rectification.
For engineers reviewing the TPMR10DH datasheet, TPMR10DH pinout, TPMR10DH application, or TPMR10DH equivalent, key selection criteria include its ultrafast trr, low VF under high DC load, thermal performance up to TJ = 175°C, and TO-277's dual-source thermal path for compact high-power designs.
Technical Context
The TPMR10DH employs a platinum-doped silicon epitaxial structure optimized for soft recovery and low switching loss. Its 35ns trr is measured at IF = 10A, IR = 1A, di/dt = 100A/µs, enabling operation in 100–300kHz PFC boost converters without excessive EMI.
Rated for 1000V repetitive peak reverse voltage (VRRM) and 10A average forward current (IF(AV)) at TC = 125°C, it supports junction temperatures up to 175°C with derating per the published thermal resistance curve (RθJC = 1.2°C/W).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000V - Withstands 1000V repetitive reverse voltage, suitable for 800V DC-link applications with safety margin. |
| IF(AV) | 10A at TC = 125°C - Sustains 10A continuous forward current when case temperature is held at 125°C. |
| trr | 35ns - Ultrafast recovery minimizes switching loss and EMI in high-frequency rectification circuits. |
| VF | 1.85V at IF = 10A - Low forward drop reduces conduction loss and improves system efficiency at rated load. |
| IR | 100µA max at VR = 1000V, TJ = 25°C - Tight leakage spec ensures reliability in high-impedance hold-up or sensing paths. |
| RθJC | 1.2°C/W - Thermal resistance from junction to case enables effective heatsinking in TO-277 footprint. |
Pinout & Package
TPMR10DH uses the JEDEC TO-277 molded plastic package (6.95 × 5.00 × 1.40 mm), with an exposed cathode pad for enhanced thermal dissipation and dual-side solderability. The package features a single cathode indicator marking (K) and conforms to IPC-7351B SOIC-277 land pattern recommendations.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 | Anode | Primary current entry point; connects to AC input or switching node in bridge/PFC configurations. |
| Terminal 2 | Cathode | Current exit terminal; electrically and thermally connected to exposed metal pad for low-inductance, low-Rθ path. |
| Exposed Pad | Cathode (common) | Integral part of cathode terminal; must be soldered to PCB copper pour for thermal and electrical continuity. |
Key Features
| Feature | Design Value |
|---|---|
| Ultrafast recovery | 35ns trr enables efficient operation in 100–300kHz SMPS and PFC topologies without snubbers. |
| High VRRM rating | 1000V withstand capability supports universal-input offline power supplies and industrial 3-phase rectifiers. |
| TO-277 thermal design | Exposed cathode pad delivers RθJC = 1.2°C/W, allowing >8W power dissipation with minimal heatsink area. |
| Soft recovery characteristic | Platinum-doped junction minimizes reverse recovery overshoot and EMI generation during turn-off. |

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, 10A IF(AV), but trr = 50ns; VF = 1.95V at 10A; TO-277A package with identical footprint. | Slightly higher trr increases switching loss in >200kHz designs; otherwise interchangeable in PFC and SMPS. | Preferred where tighter IR spec (<50µA) is required; otherwise TPMR10DH offers faster recovery. |
| ON Semiconductor MUR10100CT | 10A/1000V dual common-cathode TO-220AC; trr = 60ns; VF = 2.1V; RθJC = 2.5°C/W. | Requires larger board area and external heatsink; unsuitable for space-constrained SMT layouts. | Select only when through-hole assembly is mandated or dual-diode topology is needed; not a drop-in replacement. |
Compared with VS-10EWH10-M3 and MUR10100CT, the TPMR10DH delivers the fastest trr (35ns) and lowest VF (1.85V) in a thermally optimized TO-277 package, making it optimal for high-density, high-efficiency 100–300kHz power conversion where layout space and thermal resistance are critical.

FAQ
What is the maximum junction temperature rating for the TPMR10DH?
The TPMR10DH is rated for a maximum junction temperature (TJ) of 175°C. This specification is validated per JEDEC test conditions and allows reliable operation in high-ambient environments such as enclosed power supplies and motor drive cabinets. Derating curves in the official datasheet define safe IF(AV) limits above TC = 125°C, and the TPMR10DH maintains 100µA IR at 1000V up to TJ = 125°C.
Does the TPMR10DH have a soft recovery characteristic, and why does it matter?
Yes, the TPMR10DH exhibits a soft recovery behavior due to its platinum-doped silicon junction. This results in controlled reverse recovery current with minimal voltage overshoot and dV/dt-induced ringing. In practical terms, this reduces EMI generation and stress on adjacent switching devices-critical in high-frequency PFC and LLC resonant converters where the TPMR10DH is commonly deployed.
Can the TPMR10DH replace standard fast recovery diodes in existing 100kHz SMPS designs?
Yes, the TPMR10DH can directly replace standard fast recovery diodes rated ≤10A/1000V in 100kHz SMPS designs, provided the PCB pad layout matches TO-277 (6.95 × 5.00 mm). Its 35ns trr and 1.85V VF typically improve efficiency by 0.3–0.5% and reduce thermal rise by 8–12°C versus legacy FRDs, making the TPMR10DH a proven upgrade path without circuit redesign.
What is the thermal resistance (RθJC) of the TPMR10DH, and how is it measured?
The TPMR10DH has a junction-to-case thermal resistance (RθJC) of 1.2°C/W, measured from the silicon die to the center of the exposed cathode pad under JEDEC JESD51-14 conditions. This value assumes full-solder coverage of the cathode pad to a ≥100 mm² copper pour. The low RθJC enables >8W power dissipation at ΔT = 10°C, supporting high-power density in compact layouts where the TPMR10DH is often selected.
Is the TPMR10DH lead-free and RoHS compliant?
Yes, the TPMR10DH is manufactured using lead-free terminations and complies with RoHS Directive 2011/65/EU and REACH SVHC regulations. The device carries the "Pb-Free" marking on its package (YWF code), and all plating materials-including the nickel-palladium-gold finish on terminals-are fully exempted under RoHS Annex III. Full compliance documentation is available upon request for the TPMR10DH.
