Product details
Overview
PU4DCH from Taiwan Semiconductor is a 200V, 4A ultra-fast surface-mount rectifier diode in DO-214AB (SMC) package, featuring 25 ns reverse recovery time, 0.84 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.
For engineers reviewing the PU4DCH datasheet, PU4DCH pinout, PU4DCH application, or PU4DCH equivalent, key selection criteria include its 200V repetitive peak reverse voltage, 130A surge current rating, junction-to-lead thermal resistance of 13°C/W, and compatibility with automated SMT placement on standard PCBs.
Technical Context
The PU4DCH employs planar silicon technology to achieve ultra-fast switching performance with low conduction loss and minimal reverse recovery charge (57 nC). Its 25 ns trr and 4.9 A reverse recovery current support operation in hard-switched topologies up to several hundred kHz.
Thermally, it delivers 13°C/W junction-to-lead resistance when mounted on a 16 mm × 16 mm copper pad, enabling sustained 4A average forward current at ≤125°C ambient with appropriate board layout - critical for compact power supplies and automotive under-hood applications.

|---|---|---|---|
| Vishay VS-4EY20 | 200 V VRRM, 4 A IF, trr = 35 ns, RθJA = 60°C/W, non-AEC-Q101 | Lacks automotive qualification; higher trr increases switching loss above 200 kHz | Preferred where cost sensitivity outweighs AEC-Q101 requirement and switching frequency ≤150 kHz |

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for PU4DCH?
The PU4DCH has a VRRM rating of 200 V, verified per Taiwan Semiconductor's C2110 datasheet. This value defines the maximum reverse voltage the device can block repeatedly without breakdown. It is critical for selecting appropriate derating margins in DC/DC converter secondary-side rectification and snubber applications where transient voltage spikes may occur. The PU4DCH maintains this rating across its full operating junction temperature range of −55°C to +175°C.
Is PU4DCH qualified for automotive applications?
Yes, the PU4DCH is AEC-Q101 qualified, as explicitly stated in the official Taiwan Semiconductor documentation. This qualification includes stress tests such as temperature cycling, high-temperature reverse bias (HTRB), and unbiased highly accelerated stress test (UHAST). The PU4DCH is therefore approved for use in automotive powertrain, body electronics, and ADAS subsystems where reliability under harsh environmental conditions is required.
What is the forward voltage drop of PU4DCH at 4 A and 25°C?
The PU4DCH exhibits a typical forward voltage (VF) of 0.84 V and a maximum of 0.93 V at 4 A and 25°C, per the electrical specifications table in the C2110 datasheet. This low VF contributes to reduced conduction losses and improved thermal performance in high-current power supply designs. At elevated junction temperatures (e.g., 125°C), VF drops to 0.70 V (typ), further optimizing efficiency under load.
What package type does PU4DCH use, and what are its mechanical features?
The PU4DCH uses the DO-214AB (SMC) surface-mount package, with matte tin-plated leads compliant with J-STD-002 solderability requirements. Its molding compound meets UL 94V-0 flammability rating, and polarity is indicated by a visible cathode band. The device weighs approximately 0.200 g and is rated MSL Level 1, meaning it can be stored indefinitely before reflow without baking.
How does the thermal performance of PU4DCH compare to standard SMC rectifiers?
The PU4DCH achieves a junction-to-lead thermal resistance (RθJL) of 13°C/W when mounted on a 16 mm × 16 mm copper pad - significantly lower than typical SMC-packaged rectifiers (often >20°C/W). This enables more effective heat transfer to the PCB, supporting sustained 4 A operation without external heatsinking. Its RθJA of 57°C/W also reflects optimized thermal design for high-power-density applications.
