Product details
Overview
SMBJ58AHE3_A/H from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for robust overvoltage protection of sensitive electronics. 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, and 600 W peak pulse power rating with 10/1000 µs waveform - deployed on power rails and signal lines in industrial motor drives and automotive ECUs.
For engineers reviewing the SMBJ58AHE3_A/H datasheet, SMBJ58AHE3_A/H pinout, SMBJ58AHE3_A/H application, or SMBJ58AHE3_A/H equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), junction temperature range (−55 to +150 °C), and packaging details for reliable circuit protection design and BOM validation.
Technical Context
This unidirectional TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds VWM = 58 V, it avalanches into low-impedance conduction to divert surge energy away from downstream ICs or MOSFETs. Its glass-passivated junction ensures stable breakdown behavior and fast response time (<1 ps), while the SMB package supports automated placement and meets MSL Level 1 (260 °C reflow peak).
The device is rated for 100 A non-repetitive forward surge current (IFSM, 8.3 ms half-sine), exhibits 0.104 %/°C VBR temperature coefficient, and maintains ≤1.0 µA reverse leakage at VWM. It is AEC-Q101 qualified (HE3 suffix), RoHS-compliant, and UL-recognized (QVGQ2) for both uni- and bidirectional variants.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 58 V - Maximum continuous reverse operating voltage before clamping begins; defines safe operating margin for 48 V nominal systems. |
| VBR (min/max) | 64.4 V / 71.2 V at IT = 1 mA - Confirmed avalanche onset range; ensures predictable turn-on across temperature and unit variation. |
| VC @ IPPM | 93.6 V at 6.4 A (10/1000 µs) - Clamped voltage during worst-case surge; limits stress on protected 60 V-rated MOSFETs or controllers. |
| PPPM | 600 W - Peak pulse power handling capability; sustains 6.4 A surges without degradation under standard test conditions. |
| RθJA | 100 °C/W - Junction-to-ambient thermal resistance on 0.2" × 0.2" copper pads; enables thermal budgeting for PCB layout in high-temperature environments. |
| TJ max. | +150 °C - Maximum junction temperature; supports operation in under-hood automotive and industrial control enclosures. |
| IFSM | 100 A - Single half-sine surge current rating (8.3 ms); protects against inductive kickback from solenoids and relay coils. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, cathode-banded unidirectional configuration. Matte tin-plated leads, J-STD-002 solderable, MSL Level 1 compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to system ground or return path; completes clamping loop during transient events. |
| Cathode | High-side surge input terminal | Connected to protected line (e.g., 48 V rail or CAN-H); conducts avalanche current toward anode when VAK > VBR. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability (vibration, temperature cycling, HTRB); required for ECU, body control, and ADAS module designs. |
| 600 W peak pulse power | Handles ISO 7637-2 Pulse 1/2a/5a transients and IEC 61000-4-5 Level 4 surges without failure on properly laid-out PCBs. |
| Low clamping ratio (VC/VBR ≈ 1.4) | Minimizes overvoltage overshoot during clamping; critical for protecting 60 V-rated gate drivers and microcontrollers. |
| MSL Level 1 moisture sensitivity | Enables standard SMT reflow without baking; reduces manufacturing complexity and cost in high-volume production. |
| Glass passivated junction | Ensures stable VBR tolerance and long-term leakage stability under thermal stress and humidity exposure. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ58A-E3/52 | Commercial-grade (non-AEC-Q101), identical electrical specs and SMB package; RoHS-compliant but not automotive-qualified. | Lacks AEC-Q101 validation; suitable for industrial/commercial power supplies but not automotive ECUs or ADAS. | Select SMBJ58AHE3_A/H when automotive qualification, extended temperature operation, or long-term field reliability are mandatory. |
| SMAJ58AHE3/A | Same VWM/VBR/VC ratings but lower PPPM = 400 W; SMA (DO-214AC) package with smaller footprint and higher RθJA = 140 °C/W. | Lower surge capacity and reduced thermal performance; limited to lower-energy transients or space-constrained consumer designs. | Choose SMBJ58AHE3_A/H where 600 W surge headroom, superior thermal dissipation, or AEC-Q101 compliance are required. |
Compared with SMBJ58A-E3/52, SMBJ58AHE3_A/H adds automotive qualification and extended lifetime validation; compared with SMAJ58AHE3/A, it delivers +50 % peak power handling and 29 % lower thermal resistance - directly enabling higher-reliability protection in demanding 48 V systems.

FAQ
What is the maximum clamping voltage of SMBJ58AHE3_A/H under standard test conditions?
The SMBJ58AHE3_A/H has a maximum clamping voltage (VC) of 93.6 V at 6.4 A peak pulse current with a 10/1000 µs waveform. This value is measured per JEDEC standards and reflects the actual voltage seen by protected components during worst-case surge events - critical for ensuring compatibility with 100 V-rated downstream devices. The SMBJ58AHE3_A/H maintains this clamping performance across its full operating temperature range.
Is SMBJ58AHE3_A/H qualified for automotive applications?
Yes, SMBJ58AHE3_A/H is AEC-Q101 qualified, as confirmed by Vishay's ordering code suffix "HE3" and documentation in datasheet 88392. This qualification covers stress tests including temperature cycling, high-temperature reverse bias, and accelerated life testing - making SMBJ58AHE3_A/H suitable for engine control units, body electronics, and ADAS modules. The HE3 variant is explicitly designated for automotive use.
What does the "A/H" suffix in SMBJ58AHE3_A/H indicate?
The "A/H" suffix in SMBJ58AHE3_A/H specifies packaging and reel configuration: "A" denotes the revision code (per Vishay's revision tracking), and "H" indicates 7-inch plastic tape-and-reel packaging with 750 units per reel. This matches the preferred package code "H" listed in the Ordering Information table of datasheet 88392. The base "HE3" confirms RoHS compliance and AEC-Q101 qualification.
How does SMBJ58AHE3_A/H compare to bidirectional TVS diodes like SMBJ58CA?
SMBJ58AHE3_A/H is unidirectional and intended for DC rail protection where polarity is fixed (e.g., +48 V systems), offering lower leakage and sharper clamping in forward conduction. In contrast, SMBJ58CA is bidirectional and used for AC or differential signal lines (e.g., RS-485). SMBJ58AHE3_A/H cannot replace SMBJ58CA in symmetrical surge environments without circuit redesign - its cathode band must be correctly oriented relative to system ground.
What is the thermal resistance and how does it affect PCB layout for SMBJ58AHE3_A/H?
SMBJ58AHE3_A/H has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This value assumes minimum recommended pad layout per Vishay's package drawing. To maintain TJ ≤ 150 °C under 5.0 W steady-state dissipation, designers must allocate ≥1 cm² of internal/external copper pour per pad and avoid excessive trace length - especially in sealed automotive enclosures.
