Product details
Overview
PU6DC from Taiwan Semiconductor is a 200V, 6A ultra-fast surface-mount rectifier in DO-214AB (SMC) package, featuring 25 ns reverse recovery time, 0.85 V forward voltage at 6 A/25°C, and 175°C maximum junction temperature. It serves as a high-efficiency freewheeling or snubber diode in high-frequency DC/DC converters.
For engineers reviewing the PU6DC datasheet, PU6DC pinout, PU6DC application, or PU6DC equivalent, key selection criteria include its 200 V repetitive peak reverse voltage, 160 A surge rating, low RθJL of 12 °C/W, and RoHS/halogen-free compliance for industrial power conversion designs.
Technical Context
The PU6DC employs planar silicon technology to achieve ultra-fast switching with controlled reverse recovery characteristics-trr = 25 ns (IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A) and Qrr = 72 nC. Its single-die configuration and matte tin-plated leads support automated SMT assembly and JESD201 Class 2 whisker resistance.
Thermally, it delivers RθJC = 13 °C/W and RθJL = 12 °C/W when mounted on a 16 mm × 16 mm copper pad, enabling reliable operation up to 175°C junction temperature under sustained 6 A forward current with appropriate PCB thermal design.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum repetitive reverse blocking voltage; defines safe operating range in 200 V-rated DC/DC or snubber circuits |
| IF | 6 A - Continuous average forward current at TL = 90°C; supports compact high-current rectification without forced cooling |
| trr | 25 ns - Measured at IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A; enables >1 MHz switching in resonant topologies |
| VF | 0.85 V @ 6 A, 25°C - Low conduction loss improves system efficiency; drops to 0.71 V at 125°C junction temp |
| RθJL | 12 °C/W - Junction-to-lead thermal resistance; allows direct thermal coupling to PCB copper for passive heatsinking |
| IFSM | 160 A @ 8.3 ms - Non-repetitive surge capability; withstands startup inrush or transient overloads |
| CJ | 110 pF @ 1 MHz, 4 V - Low junction capacitance minimizes switching noise and EMI in high-dv/dt applications |
Pinout & Package
Package: DO-214AB (SMC), surface-mount, cathode indicated by band. Matte tin-plated leads, UL 94V-0 molding compound, 0.201 g typical weight.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Forward current entry point | Connected to lower-potential node (e.g., switch node in buck converter); requires adequate copper area for thermal dissipation |
| Cathode (Lead 2, banded end) | Forward current exit / reverse blocking terminal | Connected to output rail or snubber network; polarity must be observed to prevent catastrophic failure |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-fast recovery (trr ≤ 25 ns) | Reduces switching losses and ringing in hard-switched SMPS, enabling higher frequency operation without added snubbers |
| Low VF (0.85 V @ 6 A) | Minimizes conduction loss and self-heating, improving power density and thermal margin in space-constrained layouts |
| DO-214AB (SMC) package | Supports automated pick-and-place and reflow soldering; provides superior thermal performance vs. smaller SOD-123 or SMA packages |
| RoHS & halogen-free compliance | Meets IEC 61249-2-21 and J-STD-020 Level 1 moisture sensitivity; suitable for lead-free manufacturing and green product requirements |
| 175°C maximum junction temperature | Enables operation in high-ambient environments (e.g., enclosed industrial power supplies) without derating at full current |
Applications
| AC-DC Adapter Secondary Rectification | DC/DC Converter Freewheeling Diode |
|---|---|
Use Scenario: Used in the secondary side of 65–100 W offline flyback adapters powering consumer electronics. IC Role / Device Role / Timing Role: Primary rectifier converting transformer output to regulated DC; handles 6 A continuous output current. Use Value: 0.85 V VF reduces conduction loss by ~12% vs. standard fast recovery diodes, improving adapter efficiency to meet DOE VI standards. | Use Scenario: Freewheeling path in 12 V → 3.3 V synchronous buck converter for FPGA power rails. IC Role / Device Role / Timing Role: Anti-parallel body-diode replacement during high-side FET dead-time; recirculates inductor current. Use Value: 25 ns trr limits reverse recovery charge (Qrr = 72 nC), reducing cross-conduction loss and EMI generation during switching transitions. |
| Snubber Network in Motor Drive Inverters | High-Frequency UPS Output Stage |
Use Scenario: RC snubber across IGBTs in 3-phase 5–10 kW industrial motor drives operating at 10–20 kHz. IC Role / Device Role / Timing Role: Fast clamping diode absorbing inductive turn-off energy; placed in parallel with snubber capacitor. Use Value: 200 V VRRM and 160 A IFSM safely absorb repetitive 150 V spikes with sub-30 ns response, preventing IGBT overvoltage failure. | Use Scenario: Output rectification in high-frequency (100–200 kHz) double-conversion UPS systems requiring high reliability. IC Role / Device Role / Timing Role: Main output rectifier in phase-shifted full-bridge topology delivering 200 A total output current (parallel devices). Use Value: RθJL = 12 °C/W and 175°C TJMAX allow stable operation under continuous load with minimal heatsinking, extending MTBF. |
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-6EWH02-M3/45 | 200 V VRRM, 6 A IF, trr = 35 ns, DO-214AB, VF = 0.92 V @ 6 A | Higher VF and slower trr increase conduction and switching loss in >100 kHz designs | Acceptable where efficiency is secondary to cost; verify thermal margin due to +0.07 V higher VF |
| ON Semiconductor MUR620CT | 200 V VRRM, dual common-cathode die in TO-220AC, trr = 35 ns, VF = 0.95 V @ 6 A | Through-hole TO-220 package requires manual assembly and larger board area; no SMT compatibility | Only suitable if legacy through-hole layout exists; not drop-in for DO-214AB footprint |
Compared with VS-6EWH02-M3/45 and MUR620CT, the PU6DC offers the lowest combined VF/trr product (0.85 V / 25 ns), making it optimal for high-frequency, high-efficiency SMT power stages where thermal and EMI constraints are critical.

FAQ
What is the maximum repetitive peak reverse voltage rating for PU6DC?
The PU6DC has a maximum repetitive peak reverse voltage (VRRM) of 200 V, as confirmed in the Absolute Maximum Ratings table. This rating defines the highest reverse-biased voltage the device can block continuously without breakdown, making it suitable for 200 V-class DC bus or snubber applications. Exceeding this voltage risks irreversible avalanche failure.
Does PU6DC have a specified reverse recovery time, and under what test conditions?
Yes, PU6DC specifies a reverse recovery time (trr) of 25 ns, measured under conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. An alternate condition yields trr = 27 ns (IF = 6.0 A, dI/dt = 200 A/µs, VR = 100 V). These values confirm its ultra-fast classification for high-frequency switching.
What is the forward voltage drop of PU6DC at rated current and room temperature?
The forward voltage (VF) of PU6DC is 0.85 V at IF = 6 A and TJ = 25°C, with a maximum of 0.94 V under the same conditions. This low VF directly reduces conduction loss and improves thermal performance in high-current rectification paths.
Is PU6DC compatible with lead-free reflow soldering processes?
Yes, PU6DC features matte tin-plated leads compliant with J-STD-002 solderability standards and is rated for moisture sensitivity level 1 per J-STD-020-meaning it can be stored indefinitely at ≤30°C/60% RH and processed using standard lead-free reflow profiles without baking.
What package type does PU6DC use, and what are its mechanical identifiers?
PU6DC uses the DO-214AB (SMC) surface-mount package. Key identifiers include a molded plastic case meeting UL 94V-0, cathode polarity marked by a visible band, and a typical weight of 0.201 g. The package outline and suggested PCB pad layout are documented in TSC's Version A2210 datasheet.
