Product details
Overview
PU2BBH from Taiwan Semiconductor is a 2A, 100V ultra-fast surface-mount rectifier diode in DO-214AA (SMB) package, featuring 25ns reverse recovery time, 0.87V forward voltage at 2A/25°C, and AEC-Q101 qualification for automotive-grade reliability in high-frequency switching and snubber circuits.
For engineers reviewing the PU2BBH datasheet, PU2BBH pinout, PU2BBH application, or PU2BBH equivalent, key selection criteria include its 100V VRRM, 50A IFSM, 175°C TJMAX, low RθJL of 16°C/W, and DO-214AA mechanical compatibility with automated SMT assembly.
Technical Context
This ultra-fast rectifier uses planar silicon technology to achieve tight trr control (≤25ns) and low Qrr (31nC), enabling efficient operation in DC/DC converters operating above 100kHz. Its single-die configuration and cathode-band polarity marking support unambiguous PCB layout and automated optical inspection.
The device delivers stable performance across –55°C to +175°C junction temperature range, with IR ≤2µA at 25°C and ≤10µA at 125°C under rated reverse voltage, and exhibits CJ = 33pF at 1MHz/4V - critical for minimizing switching node ringing in high-di/dt applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - maximum repetitive reverse blocking voltage; defines safe operating limit in clamping/snubber circuits |
| IF | 2 A - continuous forward current rating; determines thermal design margin on 10mm × 10mm Cu pad |
| trr | 25 ns - measured at IF = 0.5A, IR = 1.0A, Irr = 0.25A; enables >500kHz switching without excessive losses |
| VF | 0.87 V @ 2A, 25°C - low conduction loss directly reduces power dissipation in high-duty-cycle rectification |
| RθJL | 16 °C/W - junction-to-lead thermal resistance; supports direct heat transfer to PCB copper for compact thermal design |
| Qrr | 31 nC - reverse recovery charge; low value minimizes turn-off losses and EMI in hard-switched topologies |
| IFSM | 50 A @ 8.3ms - surge capability ensures robustness against inrush and transient overcurrent events |
Pinout & Package
DO-214AA (SMB) surface-mount package with molded plastic case (UL 94V-0), matte tin-plated leads, and cathode polarity indicated by a visible band on the body. Weight: 0.087g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side of circuit; must be routed with adequate copper area for thermal relief |
| Cathode | Forward current exit / reverse blocking terminal | Marked by band; connects to higher-potential node; critical for correct orientation in snubber clamp paths |
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 |
|---|---|---|---|
| STTH2R010DJF | VRRM = 100V, IF = 2A, trr = 22ns, DO-214AA, but not AEC-Q101 qualified | Lacks automotive qualification; suitable for industrial/commercial only | Select when AEC-Q101 is not required and tighter trr is prioritized |
| ES2D | VRRM = 200V, IF = 2A, trr = 35ns, same DO-214AA package, RoHS/halogen-free | Higher VRRM but slower recovery; not AEC-Q101 qualified | Choose for 200V systems where speed is secondary to voltage margin |
Compared with STTH2R010DJF and ES2D, the PU2BBH uniquely combines 100V rating, 25ns trr, and AEC-Q101 qualification - making it the only option validated for automotive underhood use while maintaining competitive switching performance and thermal metrics.

FAQ
What is the maximum junction temperature rating for PU2BBH?
The PU2BBH has a maximum junction temperature (TJMAX) of +175°C, verified per absolute maximum ratings table. This allows operation in under-hood automotive environments and high-ambient industrial settings without thermal derating below 2A continuous current when mounted on a 10mm × 10mm Cu pad. The PU2BBH maintains specified electrical parameters up to this limit.
Is PU2BBH AEC-Q101 qualified, and what tests does that cover?
Yes, PU2BBH is AEC-Q101 qualified per the manufacturer's documentation. This includes stress testing for high-temperature operating life (HTOL), temperature cycling (TC), high-temperature reverse bias (HTRB), and unbiased highly accelerated stress test (uHAST). The qualification confirms suitability for automotive power electronics where reliability under thermal and electrical stress is critical.
What is the reverse recovery time (trr) specification for PU2BBH, and under what conditions is it measured?
The PU2BBH reverse recovery time is specified as ≤25ns, measured under conditions of IF = 0.5A, IR = 1.0A, and Irr = 0.25A. An alternate condition (IF = 1.0A, di/dt = 50A/µs, VR = 30V) yields trr ≤30ns. These values are confirmed in the Electrical Specifications table and support high-frequency switching up to 500kHz.
Does PU2BBH have a halogen-free and RoHS-compliant construction?
Yes, PU2BBH is both RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound meets UL 94V-0 flammability rating, and terminals are matte tin plated for solderability per J-STD-002. Moisture sensitivity level is rated at Level 1 per J-STD-020, eliminating pre-reflow baking requirements.
What is the marking code printed on the PU2BBH device body?
The PU2BBH is marked with "PU2BB" on the device body, as specified in the Absolute Maximum Ratings table. This distinguishes it from the 200V variant PU2DBH (marked "PU2DB"). The cathode is indicated by a visible band, and the date code, factory code, and green compound indicator are also included per the Marking Diagram.
