Product details
Overview
BYG23MHE3_A/H from Vishay General Semiconductor is an ultrafast avalanche SMD rectifier in SMA (DO-214AC) package, rated for 1000 V repetitive peak reverse voltage, 1.5 A average forward current at 65 °C, and 75 ns reverse recovery time. It delivers low forward voltage (1.7 V @ 1.0 A, 25 °C), 5.0 µA max reverse leakage at 25 °C, and 20 mJ avalanche energy rating - used in high-frequency freewheeling and rectification in automotive SMPS and telecom inverters.
For engineers reviewing the BYG23MHE3_A/H datasheet, BYG23MHE3_A/H pinout, BYG23MHE3_A/H application, or BYG23MHE3_A/H equivalent, key selection criteria include its AEC-Q101 qualification (HE3 suffix), MSL Level 1 moisture sensitivity, 150 °C max junction temperature, and compatibility with automated SMT placement on standard reflow profiles up to 260 °C peak.
Technical Context
This device is a single-die, planar passivated silicon rectifier optimized for high-speed switching in inductive-load circuits. Its ultrafast trr of 75 ns enables efficient operation in 100–500 kHz SMPS topologies, while the 20 mJ non-repetitive avalanche energy rating supports robust turn-off handling of inductive kickback without external snubbers.
The glass-passivated junction ensures stable IR performance across temperature (5 µA @ 25 °C, 50 µA @ 125 °C), and the SMA package provides thermal resistance of 25 °C/W (junction-to-case) and 100–150 °C/W (junction-to-ambient), depending on PCB copper area - critical for thermal design in space-constrained power stages.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1L06S | 600 V VRRM, 1.0 A IF(AV), 50 ns trr, TO-277 package | Limited to ≤600 V systems; lower surge rating (25 A) | Select when lower VRRM suffices and faster trr is prioritized over avalanche ruggedness |
| ES1J-M3/5AT | 600 V VRRM, 1.0 A IF(AV), 35 ns trr, SMA package, no avalanche rating | Not rated for inductive energy absorption; unsuitable for freewheeling in high-L circuits | Choose only for low-energy signal rectification where trr < 40 ns is mandatory and VRRM ≤ 600 V |
Compared with STTH1L06S and ES1J-M3/5AT, BYG23MHE3_A/H uniquely combines 1000 V rating, 20 mJ avalanche capability, and AEC-Q101 qualification - making it the only viable option for automotive 48 V–12 V converters requiring both high-voltage margin and inductive fault tolerance.

FAQ
What does the "HE3" suffix indicate in BYG23MHE3_A/H?
The "HE3" suffix in BYG23MHE3_A/H denotes RoHS-compliant construction with AEC-Q101 qualification for automotive applications. It confirms compliance with JESD201 Class 2 whisker testing, MSL Level 1, and full stress qualification including temperature cycling, HTRB, and HTGB - distinguishing it from commercial-grade E3 variants.
Is BYG23MHE3_A/H suitable for use in synchronous rectification circuits?
BYG23MHE3_A/H is not a synchronous rectifier IC but serves as a robust clamp or auxiliary diode in synchronous designs. Its 75 ns trr and 20 mJ avalanche rating make it ideal for managing dead-time conduction and inductive kickback when the main SR FET is off - commonly deployed alongside controllers like MP6908 or UCC24612.
What is the thermal resistance of BYG23MHE3_A/H under standard PCB mounting conditions?
BYG23MHE3_A/H has RθJC = 25 °C/W (junction-to-case) and RθJA = 150 °C/W on 17 mm² Cu, 125 °C/W on 50 mm² Cu, and 100 °C/W on Al₂O₃ ceramic with 50 mm² Cu. These values are measured per JEDEC standards and define thermal design margins for sustained 1.5 A operation in enclosed environments.
Does BYG23MHE3_A/H require special handling during reflow soldering?
No special handling is required for BYG23MHE3_A/H during reflow: it meets MSL Level 1 per J-STD-020 and supports peak temperatures up to 260 °C. Standard lead-free reflow profiles (e.g., IPC/JEDEC J-STD-020) apply - no baking or dry-packaging needed prior to assembly.
How does the avalanche energy rating of BYG23MHE3_A/H improve system reliability?
The 20 mJ non-repetitive avalanche energy rating of BYG23MHE3_A/H allows it to safely absorb inductive energy during MOSFET/IGBT turn-off without clamping circuitry. In automotive DC-DC converters, this eliminates snubber losses and prevents voltage overshoot-induced failures - directly extending field lifetime in high-L, high-dI/dt applications.
