Product details
Overview
SMBJ58CAHE3_B/I from Vishay General Semiconductor is a bidirectional surface-mount transient voltage suppressor (TVS) diode in the SMB (DO-214AA) package, designed for robust overvoltage protection of sensitive electronics. It features a 58 V standoff voltage (VWM), 64.4–71.2 V breakdown range (VBR at 1 mA), and clamps transients to ≤93.6 V at 6.4 A peak pulse current (IPPM) under 10/1000 µs waveform - deployed on power rails and signal lines in industrial sensor interfaces.
For engineers reviewing the SMBJ58CAHE3_B/I datasheet, SMBJ58CAHE3_B/I pinout, SMBJ58CAHE3_B/I application, or SMBJ58CAHE3_B/I equivalent, this device is selected for high-reliability surge suppression where bidirectional clamping, AEC-Q101 qualification, and 600 W peak pulse power capability are required in compact PCB layouts.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector with symmetrical bidirectional conduction - enabling suppression of both positive and negative polarity transients without polarity sensitivity. Its glass-passivated junction ensures stable leakage (<1.0 µA at VWM) and low incremental surge resistance, critical for fast response to ESD and lightning-induced surges.
The device is rated for 150 °C maximum junction temperature and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak. Its thermal resistance (RθJA = 100 °C/W) reflects performance on standard 0.2" × 0.2" copper pads, and it delivers 600 W peak pulse power with 0.01% duty cycle repetitive capability.
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 1 mA - Confirmed breakdown threshold range ensuring reliable turn-on during overvoltage events. |
| VC @ IPPM | ≤93.6 V at 6.4 A - Clamping voltage under 10/1000 µs surge; limits downstream IC stress to safe levels. |
| PPPM | 600 W - Peak pulse power handling capacity; supports IEC 61000-4-5 Level 4 surge immunity testing. |
| ID @ VWM | ≤1.0 µA - Ultra-low reverse leakage at standoff voltage; avoids parasitic loading on low-power sensor circuits. |
| TJ max. | +150 °C - Enables operation in under-hood automotive or industrial enclosures without derating. |
| Package | SMB (DO-214AA) - Surface-mount footprint (5.21 mm × 4.06 mm) compatible with automated placement and IPC-7351B land patterns. |
Pinout & Package
Package: SMB (DO-214AA), bidirectional configuration - no polarity marking; symmetrical terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current sink (negative half-cycle) | Provides low-impedance path to ground for negative-going surges; identical electrical behavior to cathode due to bidirectionality. |
| Cathode | Transient current sink (positive half-cycle) | Provides low-impedance path to ground for positive-going surges; functionally interchangeable with anode in this bidirectional device. |
Key Features
| Feature | Design Value |
|---|---|

| 600 W peak pulse power | Meets IEC 61000-4-5 surge immunity up to 4 kV (line-to-earth) in properly designed PCB layouts. |
| Low clamping ratio (VC/VBR ≈ 1.46) | Minimizes voltage overshoot during clamping - critical for protecting 3.3 V or 5 V logic interfaces downstream. |
| MSL Level 1, 260 °C peak reflow | Supports lead-free assembly without moisture sensitivity limitations or baking requirements. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ58CA-M3/5B | Halogen-free, RoHS-compliant variant; identical electrical specs and AEC-Q101 qualification. | No functional difference; selected when halogen-free compliance is mandated by OEM material declarations. | Choose SMBJ58CA-M3/5B if halogen-free content is required for environmental compliance reporting. |
| SAC58CA | Same VWM and VC, but in SOD-123FL package (smaller footprint, lower IPPM = 5.0 A, PPPM = 400 W). | Lower surge rating suits space-constrained consumer designs where full 600 W immunity is not required. | Choose SAC58CA only for compact layouts accepting reduced surge margin; not drop-in for SMBJ58CAHE3_B/I. |
Compared with SMBJ58CAHE3_B/I, SMBJ58CA-M3/5B offers identical protection performance with halogen-free materials, while SAC58CA trades surge capacity and thermal mass for smaller size - making SMBJ58CAHE3_B/I optimal for industrial and automotive applications demanding full 600 W rating and AEC-Q101 validation.

FAQ
What is the clamping voltage of SMBJ58CAHE3_B/I at its rated peak pulse current?
The SMBJ58CAHE3_B/I clamps to a maximum of 93.6 V at its specified peak pulse current of 6.4 A under the 10/1000 µs waveform. This value is measured per JEDEC standards and confirmed in Vishay's datasheet revision 09-Jan-2024, Document Number 88392. The clamping voltage directly determines the maximum stress imposed on downstream circuitry during surge events, making it a critical parameter for system-level overvoltage design.
Is SMBJ58CAHE3_B/I suitable for automotive applications?
Yes, SMBJ58CAHE3_B/I is AEC-Q101 qualified, as indicated by the "HE3" suffix in its part number. This certification covers stress tests including high-temperature reverse bias, temperature cycling, and ESD robustness - validating its use in automotive body control modules, infotainment power supplies, and sensor nodes. The device operates reliably from –55 °C to +150 °C, supporting under-hood and cabin environments.
How does the bidirectional configuration of SMBJ58CAHE3_B/I affect its PCB layout?
The SMBJ58CAHE3_B/I has no polarity marking and functions identically in either orientation due to its symmetrical bidirectional structure. This eliminates orientation constraints during automated placement and simplifies layout - especially beneficial for differential or floating signal lines like RS-485, CAN, or LIN buses. No cathode band alignment is required, reducing assembly errors and enabling flexible routing.
What is the maximum reverse leakage current of SMBJ58CAHE3_B/I at its standoff voltage?
The SMBJ58CAHE3_B/I exhibits a maximum reverse leakage current (ID) of 1.0 µA at its 58 V standoff voltage (VWM), measured at 25 °C. This ultra-low leakage prevents unwanted loading on high-impedance sensor outputs or battery-backed circuits. The specification is verified per ANSI/IEEE C62.35 and remains stable across temperature when used within its rated junction range.
Does SMBJ58CAHE3_B/I require special handling during reflow soldering?
No special handling is required: SMBJ58CAHE3_B/I is rated MSL Level 1 per J-STD-020 and supports peak reflow temperatures up to 260 °C. It can be processed using standard lead-free reflow profiles without pre-baking. The matte tin-plated leads comply with J-STD-002 and JESD 22-B102, ensuring reliable solder wetting and whisker resistance in high-volume manufacturing.
