Product details
Overview
PE4DCH from Taiwan Semiconductor is a 200V, 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 output rectifier in high-frequency DC/DC converters and snubber circuits where low conduction loss and fast switching are critical.
For engineers reviewing the PE4DCH datasheet, PE4DCH pinout, PE4DCH application, or PE4DCH equivalent, key selection criteria include its 200V 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 copper pads.
Technical Context
The PE4DCH employs planar silicon technology to achieve ultra-fast recovery (trr ≤ 20 ns) and low forward voltage (VF = 0.86 V @ 4A, 25°C), enabling high-efficiency operation in 100–500 kHz switching topologies. Its single-die configuration and DO-214AB package support high power density in space-constrained designs.
Thermal performance is characterized by RθJL = 15°C/W and RθJA = 56°C/W on a 16 mm × 16 mm Cu pad, with maximum junction temperature rated at +175°C and moisture sensitivity level 1 - ensuring robust reflow compatibility and long-term reliability under thermal cycling.

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-4EWH02-M3/45 | 200 V VRRM, 4 A IF, trr = 25 ns, VF = 0.92 V @ 4A - higher VF and slower recovery than PE4DCH | Higher conduction and switching loss in >200 kHz designs; less suitable for thermally constrained telecom modules | Acceptable where layout allows extra thermal margin and switching frequency ≤ 150 kHz |
| ON Semiconductor MUR420G | 200 V VRRM, 4 A IF, trr = 35 ns, VF = 0.975 V @ 4A - significantly slower and higher VF | Not recommended for snubber or high-frequency DC/DC; better suited for line-frequency rectification | Only consider if AEC-Q101 qualification is not required and cost is primary constraint |
Compared with VS-4EWH02-M3/45 and MUR420G, PE4DCH delivers superior high-frequency performance due to its 20 ns trr and 0.86 V VF, making it the preferred choice for automotive DC/DC, telecom power, and snubber networks demanding minimal switching loss and thermal footprint.

FAQ
What is the maximum junction temperature rating for PE4DCH?
The PE4DCH has a maximum junction temperature (TJ) rating of +175°C, verified per absolute maximum ratings table in the official TSC datasheet Version A2212. This rating supports operation in under-hood automotive environments and high-ambient industrial settings. Derating curves confirm usable current capacity down to 0 A at 175°C ambient when mounted on a 16 mm × 16 mm Cu pad. Thermal design must respect RθJA = 56°C/W under those conditions.
Is PE4DCH pin-compatible with PE4BCH?
No - PE4DCH and PE4BCH share identical DO-214AB (SMC) package and pinout (anode/cathode), but differ in voltage rating: PE4BCH is rated for 100 V VRRM, while PE4DCH is rated for 200 V VRRM. They are mechanically interchangeable but electrically non-substitutable without circuit review. The marking code "PE4DC" on PE4DCH distinguishes it from "PE4BC" on PE4BCH.
Does PE4DCH meet automotive qualification standards?
Yes, PE4DCH is explicitly AEC-Q101 qualified per the TSC datasheet Version A2212. This includes stress testing for high-temperature operating life (HTOL), temperature cycling (TC), and unbiased highly accelerated stress test (UHAST). The qualification applies to the exact PE4DCH ordering variant and supports use in automotive powertrain and body electronics applications.
What is the reverse recovery time (trr) specification for PE4DCH?
The PE4DCH reverse recovery time is specified as ≤ 20 ns under test condition IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A. An alternate measurement (IF = 4.0 A, di/dt = 200 A/µs, VR = 100 V) yields trr = 16.4 ns (typical). These values are confirmed in the Electrical Specifications table of the TSC PE4BCH–PE4DCH datasheet and reflect true ultra-fast behavior essential for high-frequency switching.
What does the "x" in PE4xCH ordering code represent?
In the PE4xCH ordering code, "x" denotes the voltage grade: "B" = 100 V (PE4BCH), "C" = 150 V (PE4CCH), and "D" = 200 V (PE4DCH). This coding is defined in the Ordering Information section of the TSC datasheet Version A2212 and maps directly to VRRM rating. PE4DCH is the 200 V variant and carries the device marking "PE4DC" on its cathode band.
