Product details
Overview
PU6DCH from Taiwan Semiconductor is a 200V, 6A ultra-fast surface-mount rectifier in DO-214AB (SMC) package, featuring 25 ns reverse recovery time, 0.85 V forward voltage at 6 A/25°C, and AEC-Q101 qualification for automotive-grade reliability. It serves as a primary output rectifier in high-frequency DC/DC converters and snubber circuits.
For engineers reviewing the PU6DCH datasheet, PU6DCH pinout, PU6DCH application, or PU6DCH equivalent, key selection criteria include its 200 V repetitive peak reverse voltage, 160 A surge rating, junction-to-lead thermal resistance of 12 °C/W, and compatibility with automated SMT placement on standard PCB copper pads.
Technical Context
The PU6DCH employs planar silicon technology to achieve ultra-fast switching performance with low conduction loss and minimal reverse recovery charge (72 nC). Its single-die configuration and DO-214AB package support high-power density layouts in space-constrained power stages.
Designed for operation up to 175 °C junction temperature, it delivers stable reverse leakage (<15 µA at 125 °C) and maintains low VF drift across temperature - 0.71 V typical at 6 A/125 °C - enabling efficient thermal management in automotive and industrial DC/DC modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - maximum repetitive reverse blocking voltage; defines safe operating limit in flyback or active clamp topologies |
| IF | 6 A - continuous average forward current; supports sustained output rectification in 50–100 W DC/DC designs |
| trr | 25 ns - measured at IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A; enables >500 kHz switching without excessive switching loss |
| Qrr | 72 nC - reverse recovery charge; directly impacts EMI and turn-on loss in synchronous or quasi-resonant converters |
| RθJL | 12 °C/W - junction-to-lead thermal resistance on 16 mm × 16 mm Cu pad; enables direct thermal path to PCB ground plane |
| VF @ 6 A / 25°C | 0.85 V (max) - forward voltage drop; determines conduction loss of ~5.1 W at full load, critical for efficiency optimization |
| IFSM | 160 A - non-repetitive surge current (8.3 ms); withstands inrush and fault transients in automotive 12 V systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH6S20H | 200 V, 6 A, trr = 35 ns, VF = 0.95 V max @ 6 A, TO-220AC package | Through-hole mounting; higher thermal resistance (RθJA ≈ 65 °C/W); no AEC-Q101 qualification | Preferred where board-level heat sinking is available and automotive qualification is not required |
| MBR6200 | 200 V, 6 A, Schottky construction, VF = 0.92 V typ @ 6 A, DO-214AB package, no AEC-Q101 | No reverse recovery (trr = 0), but limited to TJ ≤ 150 °C and higher leakage (>100 µA @ 125 °C) | Suitable for lower-temperature environments where zero-recovery benefit outweighs leakage and temperature limits |
Compared with STTH6S20H and MBR6200, the PU6DCH uniquely combines AEC-Q101 qualification, 25 ns trr, and DO-214AB SMT compatibility - making it the only option qualified for automotive underhood use while maintaining ultra-fast recovery and low-profile assembly.

FAQ
What is the maximum junction temperature rating for the PU6DCH?
The PU6DCH has a maximum junction temperature (TJ) rating of +175 °C, verified per AEC-Q101 stress testing. This allows continuous operation in underhood automotive environments and high-ambient industrial settings. The device maintains specified electrical parameters up to this temperature, with forward voltage dropping to 0.71 V typical at 6 A/125 °C. Thermal design must account for RθJL = 12 °C/W to ensure safe operation within this limit.
Is the PU6DCH pin-compatible with other devices in the PU6xCH family?
Yes - all PU6xCH variants (including PU6BCH, PU6CCH, and PU6DCH) share identical DO-214AB (SMC) package dimensions, pinout, and mechanical footprint. The only difference is rated VRRM: PU6BCH = 100 V, PU6CCH = 150 V, PU6DCH = 200 V. Designers may select voltage grade without layout change, provided thermal and surge margins align with the chosen variant's specifications.
Does the PU6DCH meet automotive qualification standards?
Yes, the PU6DCH is AEC-Q101 qualified, having passed all required stress tests including high-temperature operating life (HTOL), temperature cycling (TC), and highly accelerated stress test (HAST). This qualification confirms suitability for automotive powertrain, body electronics, and ADAS applications where reliability under thermal, mechanical, and environmental stress is mandatory.
What is the reverse recovery time (trr) specification for the PU6DCH?
The PU6DCH has a reverse recovery time (trr) of 25 ns, measured under IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A conditions. An alternate test condition (IF = 1.0 A, di/dt = 50 A/µs, VR = 30 V) yields 31 ns. This ultra-fast recovery minimizes switching loss and EMI in high-frequency DC/DC converters, distinguishing it from standard fast recovery diodes with trr > 50 ns.
How does the PU6DCH compare to Schottky rectifiers in the same voltage class?
Unlike Schottky rectifiers such as MBR6200, the PU6DCH uses planar silicon PN-junction technology, enabling 200 V VRRM and 175 °C operation - far exceeding typical Schottky limits of ≤150 °C and ≤100 V. While Schottkys offer zero trr, the PU6DCH's 25 ns trr and 72 nC Qrr provide superior balance of speed, voltage rating, and thermal robustness for demanding 200 V applications where Schottkys cannot operate reliably.
