Product details

Overview

PUUP3D 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 85A surge capability - deployed in high-frequency DC/DC converters and snubber circuits.

For engineers reviewing the PUUP3D datasheet, PUUP3D pinout, PUUP3D application, or PUUP3D equivalent, key selection criteria include V_RRM = 200V, I_F = 3A, t_rr ≤ 25ns, R_θJL = 2.0°C/W, and wettable flank compatibility with automated optical inspection (AOI) and reflow soldering.

Technical Context

This single-die planar ultra-fast rectifier operates with junction temperatures up to +175°C and supports repetitive peak reverse voltages up to 200V. Its low Q_rr (51nC) and fast t_rr (23–25ns) minimize switching losses in hard-switched topologies.

The TO-277A (SMPC4.6U) package delivers R_θJL = 2.0°C/W with ideal heatsinking and R_θJA = 52.4°C/W on a 16mm × 16mm Cu pad PCB - enabling compact, thermally robust designs for space-constrained power stages.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	200 V - maximum repetitive reverse blocking voltage; defines safe operating range in flyback/clamp/snubber circuits
I_F	3 A continuous - average forward current rating at T_L = 115°C; determines steady-state conduction capability
t_rr	23–25 ns - measured under IF = 0.5A/1.0A, di/dt = 50–200A/µs; enables >500 kHz switching without excessive loss
V_F	0.86 V @ 3A, 25°C - forward drop directly impacts conduction loss and thermal rise in high-duty-cycle operation
Q_rr	51 nC - reverse recovery charge; lower value reduces turn-off loss and EMI in hard-switched converters
R_θJL	2.0 °C/W - junction-to-lead thermal resistance with ideal heatsink; enables direct thermal coupling to PCB copper or heatsink
I_FSM	85 A @ 8.3 ms - non-repetitive surge rating; supports inrush and fault-current handling in DC/DC input stages

Pinout & Package

TO-277A (SMPC4.6U) surface-mount package with wettable flank leads, matte tin plating, and cathode band polarity marking. Weight: 0.102 g.

Pin/Terminal	Circuit Role	Design Meaning
1 (Anode)	Anode connection	Primary current entry point; electrically tied to die anode; requires proper trace width for 3A continuous
2 (Anode)	Anode connection	Second anode terminal - dual-anode configuration improves current sharing and thermal spreading in TO-277A layout
3 (Cathode)	Cathode connection	Current exit node; marked by cathode band; connects to output rail or switching node in snubber/clamp applications

Key Features

Alternative Part	Technical Difference	Application Difference	Selection Advice
Vishay VS-3EWH02-M3/45	V_RRM = 200V, I_F = 3A, t_rr = 25ns, but TO-277 package lacks wettable flanks and has R_θJA = 60°C/W	No AOI support; less suitable for high-reliability automated inspection in medical or automotive production	Choose PUUP3D when wettable flank AOI and lower R_θJA are required
ON Semiconductor MUR320	V_RRM = 200V, I_F = 3A, but t_rr = 35ns, Q_rr = 75nC, and TO-220AC package limits SMT scalability	Higher switching loss; through-hole mounting incompatible with fully automated SMT lines	Choose PUUP3D for surface-mount, high-frequency, and AOI-capable deployments

FAQ

What is the maximum junction temperature rating for PUUP3D?

The PUUP3D has a maximum junction temperature (T_J) rating of +175°C, verified per absolute maximum ratings table in the official datasheet. This allows reliable operation in under-hood automotive environments and high-ambient industrial applications. The PUUP3D maintains specified electrical performance across its full –55°C to +175°C junction temperature range without derating until thermal limits are approached.

Does PUUP3D support automated optical inspection (AOI)?

Yes, PUUP3D features wettable flank leads in its TO-277A (SMPC4.6U) package, enabling high-accuracy solder-joint inspection using standard AOI systems. This design meets IPC-A-610 Class 2/3 requirements and eliminates post-reflow X-ray verification in most production lines. The PUUP3D's flank geometry and matte tin plating ensure consistent reflectivity and contrast for reliable AOI detection.

What is the reverse recovery time (t_rr) of PUUP3D under typical operating conditions?

The PUUP3D exhibits t_rr = 23 ns (typical) at I_F = 3.0A, dI/dt = 200A/µs, and V_R = 100V, and t_rr = 25 ns (max) under I_F = 0.5A/1.0A test conditions. These values are measured per JEDEC JESD24-11 and confirm suitability for switching frequencies exceeding 500 kHz. The PUUP3D's t_rr remains stable across its rated temperature range.

Is PUUP3D RoHS and halogen-free compliant?

Yes, PUUP3D is RoHS compliant per Directive 2011/65/EU and halogen-free per IEC 61249-2-21. The molding compound meets UL 94V-0 flammability rating, and terminals pass JESD201 Class 2 whisker testing. These certifications are confirmed in TSC's official compliance documentation for version A2210. PUUP3D meets environmental and safety requirements for consumer, industrial, and automotive end equipment.

What is the marking code printed on the PUUP3D device body?

The PUUP3D is marked with "PU3DH" on its top surface, followed by date code (YW) and factory code (F), per the official marking diagram in the datasheet. This distinguishes it from the 100V variant PUUP3B (marked "PU3BH"). The PUUP3D's marking ensures unambiguous identification during incoming inspection and automated pick-and-place verification.
