Product details
Overview
PU2DAH from Taiwan Semiconductor is a 2A, 200V ultra-fast surface-mount rectifier diode in DO-214AC (SMA) package, featuring 25 ns reverse recovery time, 0.93 V max 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 PU2DAH datasheet, PU2DAH pinout, PU2DAH application, or PU2DAH equivalent, key selection criteria include its 200V VRRM, 50A IFSM, 175°C junction temperature rating, low RθJA of 78°C/W, and suitability for snubber circuits and automated SMT assembly.
Technical Context
This single-die, planar-junction ultra-fast rectifier uses optimized carrier lifetime control to achieve trr ≤25 ns under IF = 0.5A / IR = 1.0A / Irr = 0.25A conditions, enabling efficient operation in 100–500 kHz switching topologies. Its 33 pF junction capacitance at 4V and 1 MHz supports minimal switching loss in resonant and phase-shifted full-bridge designs.
The device operates across –55°C to +175°C junction temperature range with RθJL = 18°C/W and RθJC = 23°C/W, confirming thermal performance validated on 5 mm × 5 mm copper pad PCBs. Moisture sensitivity level 1 (per J-STD-020) and matte tin-plated leads ensure robust reflow compatibility.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R02DJF | 200V VRRM, 2A IF, trr = 22 ns, but TO-277A package (3-lead, no cathode band marking) | Requires different footprint and visual polarity verification; lacks AEC-Q101 qualification | Preferred where board space permits larger package and automotive qualification is not required |
| ES2D-E3/57T | 200V VRRM, 2A IF, trr = 35 ns, DO-214AC package, but only commercial-grade (–55°C to +150°C) | Not rated for 175°C operation or automotive environments; higher trr increases switching loss at >250 kHz | Acceptable for cost-sensitive industrial supplies below 200 kHz with ambient <85°C |
Compared with STTH2R02DJF and ES2D-E3/57T, PU2DAH uniquely combines AEC-Q101 qualification, 175°C TJ max, and 25 ns trr in DO-214AC-making it the only option qualified for under-hood automotive DC/DC and high-temp industrial converters requiring both reliability and high-frequency efficiency.

FAQ
What is the maximum repetitive peak reverse voltage rating for PU2DAH?
The PU2DAH has a maximum repetitive peak reverse voltage (VRRM) rating of 200 V, verified per absolute maximum ratings table in the official Taiwan Semiconductor datasheet revision C2110. This rating defines the highest reverse voltage the device can block repeatedly without breakdown under normal operating conditions and is strictly limited to this value for reliable long-term operation.
Is PU2DAH qualified for automotive applications?
Yes, PU2DAH is AEC-Q101 qualified, as explicitly stated in the features section of the Taiwan Semiconductor datasheet. This qualification covers stress tests including high-temperature operating life, temperature cycling, and unbiased highly accelerated stress testing-confirming its suitability for under-hood automotive power systems such as on-board chargers and DC/DC converters.
What is the reverse recovery time (trr) specification for PU2DAH?
The PU2DAH reverse recovery time is specified as ≤25 ns under test conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This value is confirmed in the Electrical Specifications table of the official datasheet and reflects the device's ultra-fast switching performance essential for high-frequency converter designs.
What package type does PU2DAH use, and what are its key mechanical attributes?
PU2DAH uses the DO-214AC (SMA) surface-mount package. Key mechanical attributes include matte tin-plated leads compliant with J-STD-002, moisture sensitivity level 1 per J-STD-020, UL 94V-0 molding compound, and cathode polarity indicated by a single black band-enabling reliable automated placement and reflow soldering.
Does PU2DAH have a halogen-free and RoHS-compliant construction?
Yes, PU2DAH is both halogen-free per IEC 61249-2-21 and RoHS compliant per EU Directive 2011/65/EU, as documented in the Features section of the Taiwan Semiconductor datasheet. These environmental qualifications are certified for the full device construction, including molding compound and lead finish.
