Product details
Overview
PE1DAH from Taiwan Semiconductor is a 200V, 1A ultra-fast surface-mount rectifier in DO-214AC (SMA) package, featuring 15 ns reverse recovery time, 0.92 V max forward voltage at 1.0 A/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 PE1DAH datasheet, PE1DAH pinout, PE1DAH application, or PE1DAH equivalent, key selection criteria include its 200V repetitive peak reverse voltage, ultra-fast trr ≤15 ns, low RθJA of 71°C/W, and suitability for snubber circuits and automated SMT assembly.
Technical Context
This single-die planar silicon rectifier operates with a maximum junction temperature of 175°C and supports surge currents up to 100 A (1.0 ms). Its ultra-fast switching is enabled by controlled carrier lifetime, yielding low Qrr (10.5 nC) and minimal stored charge.
The device exhibits low thermal resistance-RθJL = 22°C/W and RθJC = 22°C/W-when mounted on a 5 mm × 5 mm copper pad, enabling stable operation under high ambient temperatures in compact power stages.

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-1EWH02-M3/5AT | 200 V VRRM, 1 A IF, trr = 25 ns (max), VF = 0.95 V (max) - slower recovery, higher conduction loss | Higher trr increases switching loss in >250 kHz designs; suitable for lower-frequency snubbers | Prefer PE1DAH where trr ≤15 ns is required to meet EMI or efficiency targets |
| ON Semiconductor MUR120RLG | 200 V VRRM, 1 A IF, trr = 35 ns (typ), VF = 0.98 V (max), not AEC-Q101 qualified | Lacks automotive qualification; higher trr and VF reduce efficiency in high-density converters | Select PE1DAH for AEC-Q101 compliance and tighter trr spec in automotive or industrial safety-critical systems |
Compared with VS-1EWH02-M3/5AT and MUR120RLG, PE1DAH delivers superior high-frequency performance via its 15 ns trr and AEC-Q101 validation-critical for minimizing losses and ensuring reliability in automotive DC/DC and telecom SMPS.

FAQ
What is the maximum repetitive peak reverse voltage rating for PE1DAH?
The PE1DAH has a maximum repetitive peak reverse voltage (VRRM) rating of 200 V, verified per JEDEC test conditions and specified in the absolute maximum ratings table. This rating ensures reliable blocking capability in 48 V automotive systems with transient overvoltages up to ISO 7637-2 Pulse 5a. The PE1DAH maintains this rating across its full operating junction temperature range of –55°C to +175°C.
Is PE1DAH qualified for automotive applications?
Yes, PE1DAH is AEC-Q101 qualified, having passed all stress tests including high-temperature operating life (HTOL), temperature cycling (TC), and highly accelerated stress test (HAST). This qualification confirms its suitability for under-hood and powertrain-related automotive applications, such as 48 V DC/DC converters and ADAS power supplies. PE1DAH is not intended for airbag or safety-critical life-support systems.
What is the reverse recovery time (trr) of PE1DAH, and under what test conditions is it measured?
The PE1DAH reverse recovery time is rated at ≤15 ns, measured under IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A per the datasheet's electrical specifications. An alternate condition-IF = 1.0 A, di/dt = 50 A/µs, VR = 30 V-yields a typical value of 23 ns. These values reflect the device's ultra-fast switching behavior, critical for minimizing switching losses in high-frequency power converters using the PE1DAH.
Does PE1DAH have a halogen-free and RoHS-compliant construction?
Yes, PE1DAH uses halogen-free molding compound per IEC 61249-2-21 and is fully RoHS compliant. Its matte tin-plated leads meet solderability requirements per J-STD-002, and the entire assembly passes JESD201 Class 2 whisker testing. These material attributes make PE1DAH suitable for environmentally regulated markets including EU, China, and Japan, and support lead-free reflow profiles used in modern SMT lines for PE1DAH placement.
What is the thermal resistance from junction to ambient (RθJA) for PE1DAH, and how is it measured?
The PE1DAH has a junction-to-ambient thermal resistance (RθJA) of 71°C/W, measured on a standard 5 mm × 5 mm copper pad PCB per JEDEC JESD51-3. This value assumes no additional thermal vias or heatsinking. For accurate thermal design, engineers should use this RθJA with the actual power dissipation calculated from PE1DAH's VF and IF to estimate junction temperature rise above ambient.
