Product details
Overview
PUUP6BH from Taiwan Semiconductor is a 6A, 100V ultra-fast surface-mount rectifier in TO-277A (SMPC4.6U) package, featuring 25 ns reverse recovery time, 0.85 V forward voltage at 6A/25°C, and AEC-Q101 qualification for automotive-grade reliability. It serves as a high-efficiency freewheeling or snubber diode in DC/DC converters operating up to several hundred kHz.
For engineers reviewing the PUUP6BH datasheet, PUUP6BH pinout, PUUP6BH application, or PUUP6BH equivalent, key selection criteria include its 100V VRRM, wettable flank leads for solder inspection, 2.0°C/W junction-to-lead thermal resistance with heatsink, and 175°C maximum junction temperature under continuous operation.
Technical Context
The PUUP6BH employs planar silicon technology to achieve ultra-fast switching with low Qrr (72 nC) and low trr (27 ns), enabling reduced switching losses in high-frequency topologies. Its single-die configuration and TO-277A package support automated SMT placement and provide robust thermal performance via copper-leadframe construction.
Designed for automotive and industrial power conversion, the device meets JESD201 Class 2 whisker resistance, J-STD-020 Level 1 moisture sensitivity, and UL 94V-0 molding compound requirements - all verified per AEC-Q101 stress test conditions including HTGB, HTRB, and TCT.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-6EWH10 | Same TO-277A package, 6A/100V, but trr = 35 ns and Qrr = 105 nC; no AEC-Q101 qualification | Not approved for automotive use; suitable only for industrial/commercial SMPS where qualification is not required | Select when cost sensitivity outweighs automotive compliance and higher switching loss is acceptable |
| ON Semiconductor MUR610EG | TO-220AC package, 6A/100V, trr = 35 ns, Qrr = 110 nC; leaded, not wettable flank | Requires through-hole assembly or adapter; unsuitable for AOI-enabled SMT lines or space-constrained layouts | Select only if legacy TO-220 footprint must be retained and thermal mass from larger package is beneficial |
Compared with VS-6EWH10 and MUR610EG, the PUUP6BH delivers lower switching loss (27 ns vs. ≥35 ns), automotive qualification, and SMT-ready wettable flank leads - making it the preferred choice for next-generation automotive and high-density industrial power supplies where reliability, efficiency, and manufacturability are jointly critical.

FAQ
What is the maximum junction temperature rating for PUUP6BH?
The PUUP6BH has a maximum junction temperature (TJ(max)) of +175°C, validated per AEC-Q101 test conditions. This rating allows sustained operation in under-hood automotive environments and high-ambient industrial settings when used within its thermal derating curve - for example, delivering 6A continuous current with case temperature maintained at or below 115°C.
Does PUUP6BH have wettable flank leads, and why does it matter?
Yes, PUUP6BH features wettable flank leads per its TO-277A (SMPC4.6U) package specification. This design enables reliable automated optical inspection (AOI) of solder fillets on side surfaces without requiring X-ray, improving manufacturing yield and reducing post-reflow defect escapes in high-volume automotive electronics assembly lines.
Is PUUP6BH pin-compatible with PUUP6DH?
No - PUUP6BH and PUUP6DH share identical TO-277A package and pinout (dual anode, single cathode), but differ in rated VRRM (100V vs. 200V) and associated electrical parameters such as reverse leakage and thermal performance under full-rated voltage. They are mechanically interchangeable but not electrically substitutable without circuit review.
What is the reverse recovery time (trr) of PUUP6BH, and how is it measured?
The PUUP6BH specifies trr = 27 ns under conditions of IF = 6.0A, di/dt = 200A/µs, and VR = 100V. This value is measured using standardized double-pulse test methodology defined in JEDEC standards, confirming its suitability for high-frequency switching applications where fast turn-off minimizes energy loss and voltage overshoot.
Can PUUP6BH be used in place of a standard FR107 diode?
No - while both are fast rectifiers, PUUP6BH (6A, 100V, TO-277A) differs significantly from FR107 (1A, 1000V, DO-41) in current rating, package, thermal capability, and recovery speed. Substituting PUUP6BH for FR107 would risk overcurrent failure; substituting FR107 for PUUP6BH would cause excessive conduction loss and thermal runaway at 6A loads.
