Product details

Overview

PUUP4D from Taiwan Semiconductor is a 200V, 4A ultra-fast surface-mount rectifier in TO-277A (SMPC4.6U) package, featuring 25ns reverse recovery time, 0.84V forward voltage at 4A/25°C, and 130A surge capability - deployed in high-frequency DC/DC converters and snubber circuits for industrial power supplies.

For engineers reviewing the PUUP4D datasheet, PUUP4D pinout, PUUP4D application, or PUUP4D equivalent, key selection criteria include V_RRM = 200V, I_F = 4A, t_rr ≤ 25ns, R_θJA = 52.4°C/W on 16mm × 16mm PCB copper pad, and wettable flank for automated optical inspection.

Technical Context

This single-die planar ultra-fast rectifier operates with junction temperature range –55°C to +175°C and supports repetitive peak reverse voltage up to 200V. Its low Q_rr of 57nC and fast t_rr enable efficient switching in hard-commutated topologies.

The device uses matte tin-plated leads compliant with J-STD-002, meets JESD201 Class 2 whisker resistance, and carries moisture sensitivity level 1 per J-STD-020 - confirming suitability for lead-free reflow and high-volume SMT assembly.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	200 V - maximum repetitive reverse blocking voltage without breakdown
I_F	4 A - continuous average forward current at T_L = 115°C on PCB
t_rr	25 ns - reverse recovery time under IF = 0.5A, IR = 1.0A, Irr = 0.25A
V_F @ 4A/25°C	0.84 V - forward voltage drop defining conduction loss in DC/DC output stage
Q_rr	57 nC - recovered charge during turn-off, directly impacting switching loss in hard-switched SMPS
R_θJA	52.4 °C/W - thermal resistance from junction to ambient on standard 16mm × 16mm Cu pad
I_FSM	130 A - non-repetitive surge current tolerance for 8.3ms half-sine, critical for input rectification fault handling

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-4EY20-M3/45	V_RRM = 200V, I_F = 4A, t_rr = 35ns, TO-277A package, no wettable flank	Higher t_rr increases switching loss in >150kHz designs; lacks AOI-compatible flank geometry	Acceptable where cost is prioritized over EMI or AOI yield; verify layout compatibility for thermal pad
ON Semiconductor MUR420G	V_RRM = 200V, I_F = 4A, t_rr = 60ns, DO-201AD package, axial leaded	Through-hole packaging incompatible with SMT lines; significantly slower recovery limits high-frequency use	Only suitable for legacy through-hole designs or low-frequency (<50kHz) snubbers; not a drop-in replacement

Compared with VS-4EY20-M3/45 and MUR420G, PUUP4D delivers superior high-frequency performance via 25ns t_rr and enables automated optical inspection with wettable flank - making it optimal for modern SMT-based industrial power supplies requiring both efficiency and process reliability.

FAQ

What is the maximum junction temperature rating for PUUP4D?

The PUUP4D has a maximum junction temperature (T_J) rating of +175°C, verified per absolute maximum ratings table. This allows reliable operation in thermally demanding environments such as enclosed industrial power modules. The PUUP4D maintains specified electrical performance up to this limit when derated per its forward current derating curve, and its planar die construction ensures stable thermal behavior across repeated cycles.

Does PUUP4D support lead-free reflow soldering?

Yes, PUUP4D supports lead-free reflow soldering. Its matte tin-plated leads comply with J-STD-002 for solderability, and its moisture sensitivity level is rated Level 1 per J-STD-020 - meaning it can be stored indefinitely at ≤30°C/60% RH without baking prior to reflow. The PUUP4D's UL 94V-0 molding compound also withstands peak reflow temperatures up to 260°C.

What does the "x" in PUUP4x ordering code signify for PUUP4D?

The "x" in PUUP4x denotes the voltage grade: PUUP4D corresponds to the 200V V_RRM variant, while PUUP4B is the 100V version. This distinction is explicitly defined in the ordering information section of the datasheet. The PUUP4D marking code on the device body is PU4DH, confirming its 200V rating and distinguishing it from other members of the same family.

How does the wettable flank feature benefit PUUP4D in production?

The wettable flank on PUUP4D enables automated optical inspection (AOI) of solder fillets on the side edges of the TO-277A package, improving defect detection yield in high-volume SMT lines. Unlike standard gull-wing or DPAK leads, the flank geometry exposes solder meniscus for camera-based verification. This feature directly enhances process control for PUUP4D in industrial power supply manufacturing where zero-defect solder joints are critical.

Is PUUP4D pin-compatible with PUUP4B?

Yes, PUUP4D is mechanically and electrically pin-compatible with PUUP4B - both use identical TO-277A (SMPC4.6U) package, 3-pin configuration (dual anode, single cathode), and share identical footprint and thermal pad layout. The only functional difference is V_RRM: PUUP4D is rated for 200V versus PUUP4B's 100V. Therefore, PUUP4D can serve as a direct upgrade in designs requiring higher reverse voltage margin without PCB changes.
