Product details
Overview
SMBJ58HE3/52 from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage 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, and 600 W peak pulse power rating with 10/1000 µs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial power supplies.
For engineers reviewing the SMBJ58HE3/52 datasheet, SMBJ58HE3/52 pinout, SMBJ58HE3/52 application, or SMBJ58HE3/52 equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), junction temperature range (−55 to +150 °C), and compliance with UL 497B for surge protector classification.
Technical Context
This TVS diode operates as a voltage-clamping device triggered by overvoltage events exceeding its reverse stand-off voltage of 58 V. Its glass-passivated junction enables fast response time (<1 ps) and low incremental surge resistance, ensuring effective suppression of ESD, lightning-induced surges, and inductive switching transients.
The SMBJ58HE3/52 is rated for 600 W peak pulse power under 10/1000 µs waveform with 0.01 % duty cycle, and supports repetitive surge handling when thermally managed. Its cathode-band marking denotes polarity, and it meets J-STD-020 MSL Level 1 with 260 °C reflow peak temperature tolerance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 58 V - Maximum continuous reverse operating voltage before clamping begins; defines safe operating margin below breakdown. |
| VBR (min/max) | 64.4 V / 71.2 V at IT = 1 mA - Ensures reliable triggering across manufacturing variation and temperature drift. |
| VC @ IPPM | 93.6 V at 6.4 A - Clamped voltage seen by protected circuit during worst-case 600 W transient; determines downstream component stress. |
| PPPM | 600 W - Peak transient energy absorption capability with 10/1000 µs waveform; validates protection level per IEC 61000-4-5. |
| IFSM | 100 A - Non-repetitive forward surge current rating (8.3 ms half-sine); supports inrush or fault-current immunity in DC power rails. |
| TJ max. | +150 °C - Maximum junction temperature; sets thermal derating limits for sustained power dissipation in enclosed environments. |
| RθJA | 100 °C/W - Junction-to-ambient thermal resistance on standard 0.2" × 0.2" copper pads; guides PCB copper area requirements for thermal management. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile plastic case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102. Cathode identified by band marking on body.

Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing - suitable for under-hood and ADAS power rail protection. |

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 version; lacks AEC-Q101 qualification and UL 497B recognition. | Restricted to non-automotive, non-safety-critical industrial or consumer use. | Select when cost sensitivity outweighs automotive qualification or safety listing requirements. |
| SAC58-13-F | Same VWM (58 V) but lower PPPM (400 W); TO-236 (SOT-23) package with higher RθJA (~200 °C/W). | Limited to low-energy signal-line protection; unsuitable for power rail or high-current surge scenarios. | Choose only for space-constrained signal-level protection where 600 W capability is unnecessary. |
Compared with SMBJ58A-E3/52 and SAC58-13-F, the SMBJ58HE3/52 uniquely combines AEC-Q101 qualification, UL 497B listing, and full 600 W surge capacity in SMB package - making it the only option qualified for automotive power rail and industrial safety-certified designs requiring validated reliability.

FAQ
What is the breakdown voltage range of SMBJ58HE3/52?
The SMBJ58HE3/52 has a guaranteed breakdown voltage (VBR) range of 64.4 V to 71.2 V at test current IT = 1 mA, measured per ANSI/IEEE C62.35. This ensures consistent clamping behavior across production lots and temperature extremes from −55 °C to +150 °C. The SMBJ58HE3/52 maintains this specification under AEC-Q101 stress conditions.
Is SMBJ58HE3/52 suitable for automotive applications?
Yes, SMBJ58HE3/52 is AEC-Q101 qualified and UL 497B recognized (file E136766), making it approved for automotive power rail protection including body control modules, infotainment power supplies, and ADAS sensor interfaces. Its MSL Level 1 rating supports lead-free reflow without preconditioning, and its 100 A IFSM rating handles load-dump events per ISO 7637-2.
What is the maximum clamping voltage of SMBJ58HE3/52 at rated surge current?
The SMBJ58HE3/52 exhibits a maximum clamping voltage (VC) of 93.6 V at peak pulse current (IPPM) = 6.4 A, tested with 10/1000 µs waveform. This value defines the upper voltage limit imposed on protected circuitry during worst-case transients and is critical for ensuring downstream ICs remain within absolute maximum ratings.
Does SMBJ58HE3/52 have bidirectional capability?
No, SMBJ58HE3/52 is a unidirectional TVS diode, indicated by the "A" suffix and cathode band marking. Bidirectional variants use the "CA" suffix (e.g., SMBJ58CA). The SMBJ58HE3/52 conducts only in forward bias and clamps in reverse bias - appropriate for DC power rails where polarity is fixed and ground-referenced protection is required.
What is the thermal resistance of SMBJ58HE3/52, and how does it affect layout?
The SMBJ58HE3/52 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 requires minimum pad area and thermal vias for sustained surge duty cycles; exceeding 5.0 W steady-state dissipation demands additional copper or heatsinking to avoid exceeding +150 °C junction temperature.
