Product details
Overview
PUUP6DH from Taiwan Semiconductor is a 200V, 6A ultra-fast surface-mount rectifier in TO-277A (SMPC4.6U) package, featuring 25 ns reverse recovery time, 0.85 V forward voltage at 6 A/25°C, and AEC-Q101 qualification for automotive power conversion.
For engineers reviewing the PUUP6DH datasheet, PUUP6DH pinout, PUUP6DH application, or PUUP6DH equivalent, key selection criteria include repetitive peak reverse voltage (200 V), surge current capability (200 A @ 8.3 ms), junction-to-lead thermal resistance (2.0 °C/W), and wettable flank packaging for automated optical inspection.
Technical Context
This single-die planar rectifier operates with low conduction loss and fast switching dynamics, enabled by optimized carrier lifetime control and low-junction-capacitance design (96 pF @ 4 V). Its 27 ns typical reverse recovery time and 72 nC reverse recovery charge support high-frequency DC/DC converters up to several hundred kHz.
The device sustains 175°C maximum junction temperature and delivers stable performance across -55°C to +175°C ambient range. Thermal performance is characterized with RθJL = 2.0 °C/W (ideal heatsink) and RθJA = 48.7 °C/W on 16 mm × 16 mm Cu pad PCB - critical for thermally constrained automotive under-hood designs.

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-6EWH02-M3 | 200 V VRRM, 6 A IF, but trr = 35 ns (vs. 27 ns), Qrr = 95 nC (vs. 72 nC) | Higher switching loss in >300 kHz designs; less suitable for snubberless operation | Acceptable where lower cost outweighs 25% higher Qrr-related losses |
| ON Semiconductor MUR620CT | TO-220AC package (not surface-mount), 200 V, 6 A, trr = 35 ns, no AEC-Q101 qualification | Requires through-hole assembly and lacks automotive reliability validation | Only for non-automotive industrial use with manual or wave-solder constraints |
Compared with VS-6EWH02-M3 and MUR620CT, PUUP6DH offers superior high-frequency efficiency due to lower Qrr and faster trr, plus AEC-Q101 compliance and wettable flank leads - making it the preferred choice for automotive SMT power stages demanding zero rework risk and thermal resilience.

FAQ
What is the maximum junction temperature rating for PUUP6DH?
The PUUP6DH has a maximum junction temperature (TJ) rating of +175°C, verified per AEC-Q101 stress testing. This allows continuous operation in under-hood automotive environments and high-power-density industrial converters where ambient temperatures exceed 105°C. The PUUP6DH maintains stable electrical parameters up to this limit when thermal design adheres to RθJL = 2.0 °C/W guidelines.
Is PUUP6DH pin-compatible with PUUP6BH?
Yes, PUUP6DH and PUUP6BH share identical TO-277A (SMPC4.6U) package, pinout, and mechanical footprint - only VRRM differs (200 V vs. 100 V). Both use the same dual-anode/cathode terminal configuration and wettable flank leads. No PCB layout change is required when upgrading from PUUP6BH to PUUP6DH for higher reverse voltage margin.
Does PUUP6DH require moisture baking before reflow soldering?
No, PUUP6DH has Moisture Sensitivity Level (MSL) 1 per J-STD-020, meaning it can be stored indefinitely at ≤30°C/60% RH and placed directly into reflow without pre-bake. This eliminates process steps and avoids thermal stress on the die, supporting high-throughput SMT lines for automotive module production.
What is the reverse recovery charge (Qrr) of PUUP6DH and why does it matter?
The PUUP6DH specifies Qrr = 72 nC under standard test conditions (IF = 6.0 A, di/dt = 200 A/µs, VR = 100 V). This value directly determines turn-off switching loss and EMI generation in hard-switched converters. Lower Qrr reduces voltage spikes and snubber dissipation - a key advantage of PUUP6DH over alternatives like MUR620CT (Qrr ≈ 110 nC).
Can PUUP6DH be used in synchronous rectification topologies?
No, PUUP6DH is a unidirectional silicon PN junction rectifier, not a MOSFET-based synchronous rectifier. It lacks gate control and cannot be actively turned off. Its role is limited to passive, fast-recovery rectification in flyback, forward, LLC, and snubber circuits - where its 27 ns trr and low VF deliver optimal trade-off between conduction and switching loss.
