Product details
Overview
PU6BCH from Taiwan Semiconductor is a 100V, 6A ultra-fast surface-mount rectifier diode 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 PU6BCH datasheet, PU6BCH pinout, PU6BCH application, or PU6BCH equivalent, key selection criteria include its 100 V repetitive peak reverse voltage, 160 A surge current rating, junction-to-lead thermal resistance of 12 °C/W, and suitability for automated SMT assembly with moisture sensitivity level 1.
Technical Context
The PU6BCH 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 designs in constrained board space.
Thermal performance is characterized by RθJL = 12 °C/W and RθJA = 57 °C/W on a 16 mm × 16 mm Cu pad PCB, enabling reliable operation up to TJ = 175 °C. Reverse recovery time is specified at 27 ns under IF = 6.0 A, di/dt = 200 A/µs, VR = 100 V conditions.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH6L06D (STMicroelectronics) | 6 A, 600 V VRRM, 35 ns trr, TO-277 package | Higher voltage rating but slower recovery; larger footprint than DO-214AB | Select when >100 V blocking is required; not drop-in due to different package and pinout |
| ES6D (ON Semiconductor) | 6 A, 200 V VRRM, 35 ns trr, DO-214AB package | Same package but higher VRRM and slower recovery; no AEC-Q101 qualification | Acceptable for non-automotive 200 V applications; lacks automotive stress validation and has 30% higher Qrr |
Compared with STTH6L06D and ES6D, the PU6BCH offers optimal balance of 100 V rating, 27 ns recovery, AEC-Q101 qualification, and DO-214AB compatibility-making it preferred for space-constrained, high-reliability automotive DC/DC rectification where voltage margin and thermal performance are prioritized over maximum blocking capability.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for PU6BCH?
The PU6BCH has a maximum repetitive peak reverse voltage (VRRM) of 100 V, as explicitly specified in the Absolute Maximum Ratings table for the PU6BCH variant. This value is distinct from the 200 V rating of the PU6DCH variant and defines the upper limit of reverse-biased voltage the PU6BCH can block continuously without breakdown.
Is PU6BCH qualified for automotive applications?
Yes, the PU6BCH is AEC-Q101 qualified, meaning it has passed the full suite of stress tests-including temperature cycling, high-temperature reverse bias (HTRB), and highly accelerated stress testing-required for discrete semiconductors used in automotive power electronics. This qualification is documented in the official Taiwan Semiconductor datasheet for PU6BCH.
What is the reverse recovery time (trr) of PU6BCH under typical operating conditions?
The PU6BCH reverse recovery time is 27 ns when tested at IF = 6.0 A, di/dt = 200 A/µs, and VR = 100 V. An alternative condition yields 25 ns (IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A). Both values confirm its ultra-fast classification and suitability for high-frequency switching applications.
Does PU6BCH have a halogen-free and RoHS-compliant construction?
Yes, the PU6BCH uses halogen-free molding compound per IEC 61249-2-21 and is fully RoHS compliant. These environmental specifications are confirmed in the Features section and Mechanical Data of the Taiwan Semiconductor datasheet, supporting compliance in regulated industrial and automotive supply chains.
What is the thermal resistance from junction to lead (RθJL) for PU6BCH?
The PU6BCH has a typical junction-to-lead thermal resistance (RθJL) of 12 °C/W, measured under standard JEDEC test conditions using a 16 mm × 16 mm copper pad PCB. This low value enables efficient heat transfer from the die directly into the PCB copper, critical for thermally demanding automotive and industrial applications.
