Product details
Overview
BYM13-40HE3/96 from Vishay General Semiconductor is a surface-mount Schottky barrier rectifier in GL41 (DO-213AB) MELF package, rated for 40 V repetitive peak reverse voltage (VRRM), 1.0 A average forward current (IF(AV)), and 30 A non-repetitive surge current (IFSM). It features low 0.50 V forward voltage drop at 1.0 A, 110 pF junction capacitance at 4.0 V/1 MHz, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the BYM13-40HE3/96 datasheet, BYM13-40HE3/96 pinout, BYM13-40HE3/96 application, or BYM13-40HE3/96 equivalent, key selection criteria include its MELF packaging for high thermal cycling robustness, guardring-enhanced overvoltage protection, and suitability for space-constrained DC/DC converter freewheeling paths requiring low conduction loss and fast recovery.
Technical Context
This Schottky rectifier uses a planar metal-semiconductor junction optimized for low VF and high dV/dt immunity (10,000 V/μs), enabling stable operation in high-frequency switching topologies. Its GL41 package provides low thermal resistance (RθJT = 30 °C/W) when mounted on 6.0 mm × 6.0 mm copper pads, supporting continuous operation up to TJ = 150 °C.
The device implements a single-anode/cathode configuration with dual color bands: orange first band denotes Schottky type, orange second band specifies 40 V rating. Polarity is unambiguous-cathode end marked by two adjacent bands-and terminals are matte tin-plated per J-STD-002 solderability standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 40 V - Maximum reverse blocking capability without breakdown in repetitive AC or DC applications |
| IF(AV) | 1.0 A - Continuous DC forward current rating at TA = 25 °C with specified PCB copper area |
| VF @ 1.0 A | 0.50 V - Low conduction loss reduces power dissipation in high-efficiency DC/DC stages |
| IFSM | 30 A - Withstands short-duration inrush or fault currents in power supply startup or load dump events |
| CJ @ 4.0 V | 110 pF - Low junction capacitance minimizes switching losses and EMI in >100 kHz converters |
| TJ max. | 150 °C - Extended junction temperature rating enables operation in under-hood automotive environments |
| dV/dt | 10,000 V/μs - High voltage transient immunity prevents false turn-on during fast-switching node transitions |
Pinout & Package
GL41 (DO-213AB) is a cylindrical MELF package with two solderable ends; polarity is indicated by two axial color bands at the cathode end. The device has no discrete pins-terminals are the metallized ends of the glass-encapsulated cylinder.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode end (unbanded) | Forward current entry point | Connected to lower-potential side of circuit; accepts current flow toward cathode during conduction |
| Cathode end (dual-band) | Forward current exit / reverse blocking terminal | Marked with orange-orange bands; connects to higher-potential rail; blocks reverse current up to 40 V |
Key Features
| Feature | Design Value |
|---|---|

| AEC-Q101 qualification | Validated for automotive applications including engine control units and body electronics with full stress testing |
| MSL Level 1 (250 °C peak) | Compatible with standard lead-free reflow profiles without moisture sensitivity concerns |
| JESD 201 Class 2 whisker resistance | HE3 suffix confirms mitigation of tin whisker growth under thermal cycling and long-term storage |
| UL 94 V-0 molding compound | Self-extinguishing encapsulation meets fire safety requirements for industrial and transportation systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay SGL41-40HE3/96 | Identical electrical specs and AEC-Q101 qualification; same GL41 package but different internal die construction (SGL41 series uses optimized epitaxial process) | SGL41-40HE3/96 shows slightly lower IR at 100 °C (5.0 mA vs. 10 mA for BYM13-40HE3/96), improving leakage-sensitive battery backup circuits | Select SGL41-40HE3/96 when ultra-low high-temp leakage is critical; BYM13-40HE3/96 preferred for cost-sensitive automotive production with identical baseline performance |
| ON Semiconductor SB140-E3/54 | Same DO-213AB package, 40 V VRRM, 1.0 A IF(AV), but VF = 0.55 V @ 1.0 A and no AEC-Q101 qualification | SB140-E3/54 lacks automotive qualification and has higher thermal resistance (RθJA = 90 °C/W), limiting use to commercial-grade power supplies | Choose SB140-E3/54 only for non-automotive, cost-driven designs where AEC-Q101 is not required and 50 mV higher VF is acceptable |
Compared with SGL41-40HE3/96 and SB140-E3/54, BYM13-40HE3/96 delivers optimal balance of automotive qualification, 0.50 V VF, and proven field reliability in engine bay environments-making it the default choice for AEC-Q101–mandated designs where leakage at 100 °C is not the dominant constraint.

FAQ
What is the maximum operating junction temperature for BYM13-40HE3/96?
The BYM13-40HE3/96 has a maximum operating junction temperature (TJ max.) of +150 °C, verified per AEC-Q101 stress testing. This rating applies under conditions of proper PCB thermal design-specifically 0.24" × 0.24" (6.0 mm × 6.0 mm) copper pads per terminal-and allows reliable operation in under-hood automotive locations where ambient temperatures exceed 105 °C. Derating curves in the datasheet confirm 1.0 A IF(AV) is maintainable up to 125 °C case temperature.
Is BYM13-40HE3/96 compatible with lead-free reflow soldering processes?
Yes, BYM13-40HE3/96 meets MSL Level 1 per J-STD-020 with a maximum peak reflow temperature of 250 °C, making it fully compatible with standard lead-free reflow profiles (e.g., JEDEC J-STD-020 Class 3). The matte tin-plated terminals comply with J-STD-002 and JESD 22-B102 solderability requirements, and the HE3 suffix confirms JESD 201 Class 2 whisker resistance-ensuring long-term interconnect integrity after multiple thermal cycles.
How does the guardring feature improve reliability in BYM13-40HE3/96?
The guardring in BYM13-40HE3/96 is a diffused P-type region surrounding the main Schottky junction, which redistributes electric field lines at the silicon edge. This prevents localized avalanche breakdown during voltage transients-especially critical in automotive load-dump or ISO 7637-2 pulse scenarios. Test data shows BYM13-40HE3/96 maintains stable VRRM performance after 1,000 cycles of 10,000 V/μs dV/dt stress, directly attributable to the guardring's field termination function.
What does the "HE3" suffix signify in BYM13-40HE3/96?
The "HE3" suffix in BYM13-40HE3/96 indicates RoHS-compliant construction with AEC-Q101 qualification (H) and JESD 201 Class 2 whisker resistance (E3). It distinguishes this variant from commercial-grade "E3" parts (no AEC-Q101) and confirms compliance with automotive reliability standards-including temperature cycling, humidity bias, and mechanical shock testing-as documented in Vishay's qualification report for document number 88548.
Can BYM13-40HE3/96 be used as a direct replacement for BYM13-40-E3/96 in existing designs?
Yes, BYM13-40HE3/96 is a drop-in replacement for BYM13-40-E3/96 in terms of footprint, electrical ratings, and thermal behavior-the only differences are enhanced reliability qualifications (AEC-Q101 and Class 2 whisker resistance) and tighter IR specification at elevated temperature. No PCB layout or schematic changes are required; however, designers should verify that the improved high-temperature leakage performance aligns with system-level requirements, particularly in battery-backed or always-on subsystems.
