Product details
Overview
BYG20JHE3_A/I from Vishay General Semiconductor is an ultrafast avalanche SMD rectifier diode in SMA (DO-214AC) package, rated for 600 V repetitive peak reverse voltage (VRRM), 1.5 A average forward current (IF(AV)), and 75 ns reverse recovery time (trr). It delivers soft recovery characteristics and low reverse leakage (1.0 µA at 25 °C), making it suitable for high-frequency power supply rectification and freewheeling in automotive DC/DC converters.
For engineers reviewing the BYG20JHE3_A/I datasheet, BYG20JHE3_A/I pinout, BYG20JHE3_A/I application, or BYG20JHE3_A/I equivalent, key selection criteria include its AEC-Q101 qualification status, 20 mJ avalanche energy rating (ER), thermal resistance (RθJA = 100–150 °C/W depending on PCB layout), and compatibility with automated SMT placement due to its low-profile SMA package.
Technical Context
The BYG20JHE3_A/I is a single-die, unidirectional silicon rectifier optimized for high-speed switching in inductive load circuits. Its glass-passivated junction ensures stable reverse leakage and robust surge handling, while the soft recovery profile minimizes EMI generation during turn-off transitions in SMPS and motor drive freewheeling paths.
This device operates across –55 °C to +150 °C junction temperature range and is qualified to AEC-Q101 for automotive use. Its 600 V VRRM rating and 30 A non-repetitive peak surge current (IFSM) support reliable operation in 48 V and 400 V automotive subsystems and telecom power interfaces where transient clamping and controlled reverse recovery are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Maximum repetitive reverse blocking voltage; enables use in 400 V DC bus applications with safety margin. |
| IF(AV) | 1.5 A - Continuous average forward current at TA = 75 °C on FR-4 PCB (50 mm² Cu); defines steady-state power handling capability. |
| trr | 75 ns - Measured at IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A; supports switching frequencies up to ~2 MHz in resonant topologies. |
| ER | 20 mJ - Avalanche energy rating at TJ = 25 °C; allows safe inductive turn-off without external snubbing in relay or solenoid drivers. |
| VF at IF = 1.5 A | 1.4 V - Forward voltage drop determines conduction loss and thermal rise in high-duty-cycle rectifiers. |
| IR at VRRM | 1.0 µA @ 25 °C - Low leakage preserves efficiency in standby modes and high-impedance sensing circuits. |
| RθJA | 100–150 °C/W - Thermal resistance varies with copper area; 100 °C/W achievable with 50 mm² 35 µm Cu on Al₂O₃ ceramic substrate. |
Pinout & Package
SMA (DO-214AC) surface-mount package with matte tin-plated leads, RoHS-compliant and AEC-Q101 qualified. Cathode identified by color band. Molding compound meets UL 94 V-0.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side of source (e.g., transformer secondary or switch node); must handle 30 A surge pulses. |
| Cathode | Forward current exit / reverse blocking terminal | Connected to output rail or ground return; polarity marking ensures correct orientation during automated placement. |
Key Features
| Feature | Design Value |
|---|---|
| Ultrafast soft recovery | 75 ns trr with low reverse recovery charge (Qrr ≈ 25 nC typical) reduces EMI and voltage overshoot in flyback and buck converters. |
| AEC-Q101 qualification | Validated for automotive underhood applications including engine control modules and ADAS power supplies. |
| Glass passivated junction | Ensures long-term stability of IR and VF over temperature and lifetime, critical for industrial power supplies requiring >10-year reliability. |
| MSL Level 1 (260 °C peak) | Enables standard lead-free reflow without moisture sensitivity concerns, eliminating bake requirements pre-assembly. |
| Low profile SMA package | Height ≤ 2.29 mm allows integration into space-constrained consumer and telecom power modules. |

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 A IF(AV), 50 ns trr, TO-277 package (single-diode variant of DPAK) | Lower average current rating; higher thermal resistance (RθJA ≈ 180 °C/W) limits power density | Prefer when board space allows larger footprint and lower trr is prioritized over current capacity. |
| ES1J-M3/5AT | 600 V VRRM, 1 A IF(AV), 35 ns trr, SMA package, no AEC-Q101 qualification | Lacks automotive qualification; lower ER (12 mJ) and higher IR (5 µA) | Select for cost-sensitive consumer power supplies where AEC-Q101 and avalanche robustness are not required. |
Compared with STTH1L06S and ES1J-M3/5AT, the BYG20JHE3_A/I uniquely combines 1.5 A current rating, 600 V blocking, AEC-Q101 qualification, and 20 mJ avalanche energy in the compact SMA package-making it optimal for automotive and industrial power stages demanding both reliability and space efficiency.

FAQ
What is the maximum junction temperature rating for BYG20JHE3_A/I?
The BYG20JHE3_A/I has a maximum operating junction temperature (TJ max.) of +150 °C and a storage temperature range of –55 °C to +150 °C. This rating is validated per AEC-Q101 stress testing and supports under-hood automotive deployment. Derating curves in the datasheet show IF(AV) decreases linearly above 75 °C ambient, requiring appropriate thermal design for sustained 1.5 A operation.
Is BYG20JHE3_A/I pin-compatible with other BYG20x variants like BYG20DHE3_A/I or BYG20GHE3_A/I?
Yes, BYG20JHE3_A/I shares identical SMA (DO-214AC) package dimensions, pinout, and mechanical footprint with BYG20DHE3_A/I and BYG20GHE3_A/I. The only differences are electrical: VRRM ratings (200 V, 400 V, 600 V respectively) and minor variations in VF and trr. No PCB redesign is needed when upgrading within the BYG20x family for higher voltage margin.
Does BYG20JHE3_A/I require special handling for moisture sensitivity?
No. BYG20JHE3_A/I is rated MSL Level 1 per J-STD-020, with a maximum peak reflow temperature of 260 °C. It does not require baking or dry-pack handling prior to SMT assembly, simplifying manufacturing flow and reducing process risk in high-volume production environments.
What does the "HE3" suffix indicate in BYG20JHE3_A/I?
The "HE3" suffix in BYG20JHE3_A/I denotes RoHS-compliant construction with AEC-Q101 qualification. "H" indicates the packaging option (13″ tape-and-reel, 7500 pcs), and "E3" confirms compliance with EU RoHS Directive 2011/65/EU. This distinguishes it from commercial-grade "E3" or halogen-free "HM3" variants.
Can BYG20JHE3_A/I be used as a direct replacement for BYG20J-E3/TR in existing designs?
Yes, BYG20JHE3_A/I is functionally and mechanically identical to BYG20J-E3/TR, differing only in packaging format (13″ reel vs. 7″ reel) and qualification level (AEC-Q101 vs. commercial). Both share identical electrical specs, thermal performance, and SMA footprint-making BYG20JHE3_A/I a drop-in upgrade for automotive or high-reliability applications.
