Product details
Overview
PUUP3DH from Taiwan Semiconductor is a 200V, 3A ultra-fast surface-mount rectifier in TO-277A (SMPC4.6U) package, featuring 25ns reverse recovery time, 0.86V forward voltage at 3A/25°C, and AEC-Q101 qualification for automotive-grade reliability. It serves as a high-efficiency freewheeling or snubber diode in DC/DC converters operating above 100 kHz.
For engineers reviewing the PUUP3DH datasheet, PUUP3DH pinout, PUUP3DH application, or PUUP3DH equivalent, key selection criteria include its 200V VRRM, wettable flank leads for solder-joint inspection, JESD201 Class 2 whisker resistance, and thermal resistance of 2.0°C/W (junction-to-lead with ideal heatsink).
Technical Context
This device is a single-die planar silicon rectifier optimized for high-frequency switching. Its 23–31 ns reverse recovery time (trr), 51 nC reverse recovery charge (Qrr), and 4.9 A peak reverse recovery current (IRM) enable low-loss operation in hard-switched topologies.
Thermally, it supports continuous operation up to 175°C junction temperature with RθJL = 2.0°C/W under ideal heatsinking and RθJA = 52.4°C/W on a 16 mm × 16 mm PCB copper pad - critical for compact power stage layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - maximum repetitive reverse voltage; defines safe blocking capability in 170 VAC rectification or 150 V bus snubbers |
| IF | 3 A - average forward current rating; supports continuous conduction mode in 25 W–40 W DC/DC stages |
| trr | 23–31 ns - ultra-fast recovery window; minimizes switching loss and EMI in >100 kHz converters |
| VF @ 3A, 25°C | 0.86 V (max) - low conduction loss; enables <0.5 W dissipation at full load without forced cooling |
| RθJL | 2.0 °C/W - junction-to-lead thermal resistance with ideal heatsink; allows direct thermal coupling to copper pour or heatsink tab |
| Qrr | 51 nC - reverse recovery charge; determines turn-off energy loss and snubber sizing in flyback or LLC resonant circuits |
Pinout & Package
Package: TO-277A (SMPC4.6U), surface-mount, single-anode dual-cathode configuration with wettable flank leads and cathode band polarity marking. Weight: 0.102 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Anode) | Anode connection | Primary current entry point; connects to switch node or transformer secondary in flyback/freewheeling paths |
| 2 (Anode) | Anode connection | Second anode terminal - electrically tied internally to Pin 1; enables dual-side PCB routing or parallel layout symmetry |
| 3 (Cathode) | Cathode connection | Common output terminal; routed to output capacitor or ground return; marked by visible cathode band |
Key Features

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-3EWH02-M3/45 | 200 V VRRM, 3 A IF, but trr = 35 ns (vs. PUUP3DH's 23–31 ns); RθJA = 60°C/W (vs. 52.4°C/W) | Higher switching loss in >150 kHz designs; less effective thermal dissipation on same PCB area | Acceptable where trr margin >10 ns and thermal headroom exists |
| ON Semiconductor MUR320SFT1G | 200 V VRRM, 3 A IF, trr = 35 ns, but no AEC-Q101 qualification or wettable flank leads | Not suitable for automotive production; AOI inspection not supported; requires moisture baking (MSL 3) | Only for cost-sensitive industrial non-automotive use with relaxed reliability and assembly requirements |
Compared with VS-3EWH02-M3/45 and MUR320SFT1G, PUUP3DH delivers lower trr, better thermal performance, and automotive-grade process validation - making it preferred for space-constrained, high-reliability, or high-frequency power conversion where manufacturability and lifetime stability are prioritized.

FAQ
What is the maximum junction temperature rating for PUUP3DH?
The PUUP3DH has a maximum junction temperature (TJ) rating of +175°C, verified per absolute maximum ratings table. This allows continuous operation in high-ambient environments such as under-hood automotive modules or enclosed industrial power supplies. Derating begins above 125°C ambient, and the device maintains full 3 A IF capability up to 100°C case temperature when mounted on a 16 mm × 16 mm Cu pad.
Does PUUP3DH have wettable flank leads, and why does it matter?
Yes, PUUP3DH features wettable flank leads per its mechanical data. This design enables reliable solder fillet formation along the vertical sidewall of the lead, allowing automated optical inspection (AOI) to verify joint integrity - a critical requirement for automotive and high-reliability manufacturing. Without wettable flanks, bottom-side solder joints on TO-277A packages cannot be reliably inspected.
Is PUUP3DH pin-compatible with PUUP3BH, and what differs between them?
Yes, PUUP3DH is mechanically and electrically pin-compatible with PUUP3BH - both use identical TO-277A (SMPC4.6U) package, pinout, and thermal characteristics. The sole difference is VRRM: PUUP3BH is rated for 100 V, while PUUP3DH is rated for 200 V. Marking codes differ (PU3BH vs. PU3DH), and all other parameters including IF, trr, and thermal resistance are identical.
What is the reverse recovery time (trr) specification for PUUP3DH, and how is it measured?
PUUP3DH specifies trr = 23 ns (typical) and ≤31 ns (max), measured under two conditions: (1) IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A; and (2) IF = 1.0 A, di/dt = 50 A/µs, VR = 30 V. These test conditions reflect real-world hard-switching behavior in DC/DC and snubber circuits, ensuring the value is directly applicable to loss calculation and EMI prediction.
Does PUUP3DH meet automotive qualification standards, and which ones?
Yes, PUUP3DH is AEC-Q101 qualified - the industry-standard stress test qualification for discrete semiconductors used in automotive applications. This includes testing for high-temperature operating life (HTOL), temperature cycling (TC), high-temperature reverse bias (HTRB), and unbiased highly accelerated stress test (UHAST). Certification confirms suitability for under-hood and powertrain-related systems.
