Product details
Overview
PU3DCH from Taiwan Semiconductor is a 200V, 3A ultra-fast surface-mount rectifier diode in DO-214AB (SMC) package, featuring 25 ns reverse recovery time, 0.86 V forward voltage at 3.0 A/25°C, and AEC-Q101 qualification for automotive-grade reliability. It serves as a primary switching rectifier in high-frequency DC/DC converters.
For engineers reviewing the PU3DCH datasheet, PU3DCH pinout, PU3DCH application, or PU3DCH equivalent, key selection criteria include its 200 V repetitive peak reverse voltage, 85 A surge current rating, junction-to-lead thermal resistance of 14 °C/W, and suitability for snubber circuits requiring fast recovery and low conduction loss.
Technical Context
The PU3DCH employs planar silicon technology to achieve ultra-fast recovery (trr ≤ 25 ns) with low Qrr (51 nC), enabling high-efficiency operation in hard-switched topologies. Its single-die configuration and DO-214AB package support automated placement and meet JESD201 Class 2 whisker resistance.
Thermal performance is characterized by RθJL = 14 °C/W and RθJA = 58 °C/W on a 16 mm × 16 mm Cu pad PCB, allowing sustained 3 A average forward current up to 175 °C junction temperature. Reverse leakage remains ≤10 µA at 125 °C under rated VR.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH3L06S | 600 V VRRM, 3 A, trr = 35 ns, VF = 0.95 V @ 3 A | Higher voltage rating but slower recovery and higher VF; suited for 400 V PFC stages, not 200 V snubbers | Select when system requires >300 V blocking; avoid where trr < 30 ns is critical |
| ES3D-E3/57T | 200 V VRRM, 3 A, trr = 35 ns, VF = 0.87 V @ 3 A, non-AEC-Q101 | Same voltage/current rating but slower recovery and no automotive qualification | Acceptable for industrial SMPS; not recommended for automotive or mission-critical snubbers |
Compared with STTH3L06S and ES3D-E3/57T, the PU3DCH delivers superior speed (25 ns vs. ≥35 ns) and automotive qualification-critical for snubber and high-frequency DC/DC use where timing precision and reliability are non-negotiable.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for PU3DCH?
The PU3DCH has a VRRM of 200 V, confirmed in the Absolute Maximum Ratings table. This rating defines its safe continuous reverse-blocking capability in circuits such as 200 V-rated snubbers and 48 V–200 V DC/DC outputs. Exceeding this voltage risks avalanche breakdown or permanent damage.
Is PU3DCH qualified for automotive applications?
Yes, PU3DCH is AEC-Q101 qualified per the manufacturer's documentation. This qualification covers stress tests including high-temperature operating life (HTOL), temperature cycling (TC), and high-temperature reverse bias (HTRB), making PU3DCH suitable for under-hood and chassis-mounted automotive power modules.
What is the forward voltage (VF) of PU3DCH at 3.0 A and 25°C?
The forward voltage of PU3DCH is 0.86 V (typical) and 0.93 V (maximum) at 3.0 A and 25°C, as specified in the Electrical Specifications table. This low VF directly reduces conduction loss and improves thermal performance in high-current rectification paths.
What package type does PU3DCH use, and is it lead-free?
PU3DCH uses the DO-214AB (SMC) surface-mount package with matte tin-plated leads. It is RoHS compliant and halogen-free per IEC 61249-2-21, meeting JEDEC J-STD-020 moisture sensitivity level 1 and JESD 201 Class 2 whisker resistance requirements.
What is the reverse recovery time (trr) of PU3DCH, and how is it measured?
The reverse recovery time of PU3DCH is 25 ns maximum, measured under conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This value reflects its ultra-fast switching behavior and is critical for minimizing switching loss in high-frequency power converters using PU3DCH.
