Product details

Overview

PU2BLWH from Taiwan Semiconductor is a 2A, 100V ultra-fast surface-mount rectifier in SOD-123W package, featuring 25ns reverse recovery time, 0.87V forward voltage at 2A/25°C, and AEC-Q101 qualification for automotive-grade reliability. It serves as a primary output rectifier in high-frequency DC/DC converters.

For engineers reviewing the PU2BLWH datasheet, PU2BLWH pinout, PU2BLWH application, or PU2BLWH equivalent, key selection criteria include its 100V V_RRM, 50A I_FSM, 175°C T_J_MAX, low Q_rr of 31nC, and SOD-123W thermal performance (R_θJL = 17°C/W).

Technical Context

The PU2BLWH employs planar silicon technology to achieve ultra-fast switching with trr ≤ 25ns under IF = 0.5A/IR = 1.0A conditions and 30ns under IF = 1.0A/di/dt = 50A/µs. Its single-die configuration supports unidirectional conduction with cathode-band polarity marking.

Thermal design is enabled by R_θJA = 75°C/W on a 5mm × 5mm Cu pad PCB and R_θJC = 22°C/W, while moisture sensitivity is rated J-STD-020 Level 1 - suitable for standard reflow without dry-pack requirements.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	100 V - maximum repetitive reverse voltage before breakdown; defines safe operating range in snubber or flyback clamp circuits
I_F	2 A - continuous forward current rating; determines minimum trace width and heatsinking in 12V–48V DC/DC outputs
t_rr	19–25 ns - measured reverse recovery time; enables >500 kHz switching without excessive switching loss
Q_rr	31 nC - reverse recovery charge; directly impacts EMI and diode-induced voltage spikes in hard-switched topologies
V_F @ 2A, 25°C	0.87 V - forward voltage drop; sets conduction loss baseline (1.74 W at 2A) for thermal budgeting
R_θJL	17 °C/W - junction-to-lead thermal resistance; enables direct thermal coupling to PCB copper for passive cooling
T_J_MAX	175 °C - maximum junction temperature; supports operation in under-hood automotive environments

Pinout & Package

Package: SOD-123W - surface-mount plastic case with matte tin-plated leads, UL 94V-0 molding compound, and cathode band polarity indicator. Weight: 0.015 g.

Pin/Terminal	Circuit Role	Design Meaning
Anode	Forward current entry point	Connected to lower-potential node (e.g., switch node in buck sync rectifier or transformer secondary center-tap)
Cathode	Forward current exit / reverse blocking terminal	Marked by band; ties to output rail or positive bus - must withstand full V_RRM during off-state

Key Features

Feature	Design Value
AEC-Q101 qualified	Validated for automotive powertrain and body electronics per stress-test requirements (HTOL, TC, UHAST)
Ultra-fast trr ≤ 25 ns	Reduces switching loss and ringing in >300 kHz DC/DC converters, especially in LLC and active clamp topologies
Low Q_rr = 31 nC	Minimizes voltage overshoot across MOSFETs during turn-on, easing gate driver and layout design
R_θJL = 17 °C/W	Enables efficient heat transfer to PCB copper without external heatsink - critical for space-constrained modules
Moisture sensitivity Level 1	Permits standard SMT reflow without baking or dry-pack handling - reduces manufacturing overhead

Equivalent & Alternatives

The following parts are listed as comparable options for similar ultra-fast rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH2R010S	100V V_RRM, 2A I_F, but trr = 35ns (vs. PU2BLWH's 19–25ns); higher V_F = 0.95V @ 2A	Less suitable for >350 kHz designs due to higher switching loss and EMI	Prefer PU2BLWH where t_rr and Q_rr are critical; STTH2R010S acceptable for cost-sensitive 100–200 kHz applications
ES2D	200V V_RRM, same SOD-123 package, but trr = 35ns and Q_rr = 45nC; not AEC-Q101 qualified	Lacks automotive qualification and exhibits higher recovery losses	PU2BLWH preferred for AEC-Q101 compliance and efficiency-critical designs; ES2D only for non-automotive 200V margin needs

Compared with STTH2R010S and ES2D, the PU2BLWH delivers superior high-frequency performance via lower t_rr and Q_rr, tighter thermal resistance (R_θJL = 17°C/W), and mandatory AEC-Q101 validation - making it the optimal choice for automotive and high-efficiency power conversion.

FAQ

What is the peak repetitive reverse voltage rating for PU2BLWH?

The PU2BLWH has a peak repetitive reverse voltage (V_RRM) rating of 100 V, verified per absolute maximum ratings table in the official Taiwan Semiconductor datasheet revision B2109. This rating defines the maximum reverse-bias voltage the device can block repeatedly without avalanche breakdown under normal operating conditions.

Is PU2BLWH qualified for automotive applications?
