Product details
Overview
SMBJ58AHE3_B/I from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping fast-rising ESD and surge transients on power and signal lines. It features a 58 V stand-off voltage (VWM), 64.4–71.2 V breakdown voltage (VBR) at 1 mA, 93.6 V maximum clamping voltage (VC) at 6.4 A peak pulse current (IPPM), and 600 W peak pulse power (10/1000 µs waveform), commonly deployed to protect MOSFET gate drivers and industrial sensor interfaces.
For engineers reviewing the SMBJ58AHE3_B/I datasheet, SMBJ58AHE3_B/I pinout, SMBJ58AHE3_B/I application, or SMBJ58AHE3_B/I equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), junction temperature range (–55 °C to +150 °C), and RoHS-compliant packaging details - all critical for automotive-grade surge protection design-in.
Technical Context
This unidirectional TVS diode operates as a voltage-clamping device triggered by reverse-biased avalanche breakdown. Its glass-passivated junction ensures stable VBR tolerance (±5% typical) and low incremental surge resistance, enabling consistent clamping performance across repetitive 10/1000 µs transients at 0.01% duty cycle.
Designed for surface-mount assembly on 0.2" × 0.2" copper pads per JEDEC standard, it delivers 600 W peak pulse power dissipation with thermal resistance of 100 °C/W (junction-to-ambient) and 20 °C/W (junction-to-lead), supporting operation up to 150 °C junction temperature under defined PCB layout conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 58 V - Maximum continuous reverse operating voltage before significant leakage; defines safe DC bias margin for protected line. |
| VBR min/max | 64.4 V / 71.2 V at IT = 1 mA - Confirmed breakdown threshold range; ensures reliable turn-on within specified tolerance for transient suppression. |
| VC @ IPPM | 93.6 V at 6.4 A - Clamped voltage during 10/1000 µs surge; determines maximum stress imposed on downstream ICs during transient events. |
| PPPM | 600 W - Peak pulse power handling capability; validates robustness against IEC 61000-4-5 Level 4 surges when mounted per recommended pad layout. |
| ID @ VWM | 1.0 µA max - Reverse leakage at rated stand-off voltage; guarantees minimal quiescent power loss and signal integrity in high-impedance circuits. |
| TJ max | +150 °C - Maximum junction temperature; enables use in under-hood automotive environments and industrial enclosures without derating. |
| RθJA | 100 °C/W - Thermal resistance junction-to-ambient on standard 0.2" × 0.2" pads; informs heatsinking requirements for sustained surge duty cycles. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ58AHM3_B/I | Halogen-free variant with identical electrical specs and AEC-Q101 qualification; same SMB package and pinout. | Required where halogen-free compliance is mandated by OEM environmental policy (e.g., Tier 1 automotive supply chain). | Select SMBJ58AHM3_B/I when halogen-free materials are contractually required; otherwise SMBJ58AHE3_B/I offers standard RoHS compliance. |
| SMCJ58AHE3_A/H | Higher-power 1500 W version in larger SMC (DO-214AB) package; VWM = 58 V, VC = 93.6 V, but RθJA = 50 °C/W and IPPM = 16 A. | Suitable for higher-energy surge environments (e.g., outdoor telecom cabinets) where PCB space allows larger footprint. | Choose SMCJ58AHE3_A/H only if 600 W is insufficient and layout permits SMC package; SMBJ58AHE3_B/I remains optimal for space-constrained automotive modules. |
Compared with SMBJ58AHM3_B/I, SMBJ58AHE3_B/I provides identical surge performance with standard RoHS compliance but excludes halogen-free certification; versus SMCJ58AHE3_A/H, it trades 2.5× lower peak power for 40% smaller PCB area and tighter thermal constraints in compact modules.

FAQ
What is the clamping voltage of SMBJ58AHE3_B/I at its rated peak pulse current?
The SMBJ58AHE3_B/I has a maximum clamping voltage (VC) of 93.6 V at 6.4 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during surge events, ensuring compatibility with 100 V-rated downstream components.
Is SMBJ58AHE3_B/I qualified for automotive applications?
Yes, SMBJ58AHE3_B/I is AEC-Q101 qualified, as confirmed by Vishay's ordering code suffix "HE3" and documentation in datasheet 88392 (Revision 09-Jan-2024). This qualification covers stress tests including HTOL, temperature cycling, and ESD, making SMBJ58AHE3_B/I suitable for engine control, body electronics, and ADAS subsystems.
What is the thermal resistance of SMBJ58AHE3_B/I and how does it affect layout?
SMBJ58AHE3_B/I has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" copper pads per JEDEC guidelines. This value requires adherence to Vishay's recommended pad layout to avoid thermal runaway during repetitive surges; reducing pad size increases RθJA and may derate peak power handling.
Does SMBJ58AHE3_B/I have bidirectional capability?
No, SMBJ58AHE3_B/I is a unidirectional TVS diode, indicated by the "A" suffix and cathode band marking. Bidirectional variants use the "CA" suffix (e.g., SMBJ58CA); using SMBJ58AHE3_B/I in bidirectional signal paths would require external circuitry to prevent forward conduction during normal operation.
What does the "_B/I" suffix mean in SMBJ58AHE3_B/I?
The "_B/I" suffix in SMBJ58AHE3_B/I specifies tape-and-reel packaging: "I" denotes 13-inch diameter reels containing 3200 units, while "B" indicates the revision level of the manufacturing process and test flow. This format ensures automated SMT placement compatibility and traceability per Vishay's ordering information table.
