Product details
Overview
PE4BCH from Taiwan Semiconductor is a 100V, 4A ultra-fast surface-mount rectifier in DO-214AB (SMC) package, featuring 20 ns reverse recovery time, 0.86 V forward voltage at 4A/25°C, and AEC-Q101 qualification for automotive-grade reliability. It serves as a primary switching rectifier in high-frequency DC/DC converters and snubber networks where low conduction loss and fast turn-off are critical.
For engineers reviewing the PE4BCH datasheet, PE4BCH pinout, PE4BCH application, or PE4BCH equivalent, key selection criteria include its 100V repetitive peak reverse voltage, 130A surge rating, junction-to-lead thermal resistance of 15°C/W, and compatibility with automated SMT placement on standard PCB pads.
Technical Context
The PE4BCH employs planar silicon technology to achieve ultra-fast recovery (trr ≤ 20 ns) and low forward voltage drop, enabling high-efficiency operation in switching frequencies up to several hundred kHz. Its single-die configuration and DO-214AB package support high power density while maintaining robust thermal performance under pulsed load conditions.
With a maximum junction temperature of 175°C and JESD201 Class 2 whisker resistance, the PE4BCH is engineered for sustained operation in thermally demanding environments such as automotive engine control units and industrial power supplies where reliability across wide temperature ranges is mandatory.

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-4EYH01-M3/45 | 100V VRRM, 4A IF, trr = 25 ns, VF = 0.89 V @ 4A/25°C, same DO-214AB package | Slightly slower recovery and higher VF increase conduction + switching loss by ~5% in 200 kHz designs | Acceptable for cost-sensitive non-automotive applications where AEC-Q101 is not required |
| ON Semiconductor MUR410EG | 100V VRRM, 4A IF, trr = 35 ns, VF = 0.87 V @ 4A/25°C, DO-201AD package (larger, axial lead) | Slower recovery increases snubber loss; through-hole mounting incompatible with fully SMT production | Only suitable for prototyping or legacy board upgrades where SMT is not feasible |

FAQ
What is the maximum repetitive peak reverse voltage rating for PE4BCH?
The PE4BCH has a maximum repetitive peak reverse voltage (VRRM) rating of 100 V, verified per the manufacturer's absolute maximum ratings table. This value defines the highest reverse voltage the device can block repeatedly without breakdown under normal operating conditions. Exceeding 100 V risks avalanche failure. The PE4BCH is part of a series where "B" denotes the 100V variant, distinct from PE4DCH (200V).
Is PE4BCH qualified for automotive applications?
Yes, PE4BCH is AEC-Q101 qualified, confirming it has passed stress tests including temperature cycling, high-temperature reverse bias, and unbiased highly accelerated stress testing. This qualification makes PE4BCH suitable for automotive power systems such as engine control unit (ECU) auxiliary supplies and ADAS subsystems where reliability under thermal and mechanical stress is mandatory.
What is the forward voltage drop of PE4BCH at full rated current?
The PE4BCH exhibits a typical forward voltage drop (VF) of 0.86 V at 4 A and 25°C, with a maximum of 0.93 V under the same conditions. At elevated junction temperature (125°C), VF drops to 0.71 V typical. These values are measured using pulse testing (PW = 0.3 ms) and directly determine conduction losses in power stage design.
Does PE4BCH have a defined reverse recovery time, and how is it measured?
Yes, PE4BCH has a specified reverse recovery time (trr) of ≤20 ns, measured under conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. An alternate test condition (IF = 1.0 A, di/dt = 50 A/µs, VR = 30 V) yields trr ≤ 22 ns. This parameter reflects the time required for minority carriers to clear after forward conduction, directly impacting switching loss in high-frequency converters.
What package type does PE4BCH use, and what are its key mechanical features?
PE4BCH uses the DO-214AB (SMC) surface-mount package. Key mechanical features include a UL 94V-0 compliant molding compound, matte tin-plated leads meeting J-STD-002 solderability, JESD201 Class 2 whisker resistance, cathode polarity indicated by a band, and a nominal weight of 0.200 g. Its standardized footprint supports automated placement and reflow soldering per J-STD-020 Level 1.
