Product details
Overview
SMBJ58CAHE3_A/H from Vishay General Semiconductor is a bidirectional 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 standoff voltage (VWM), 64.4–71.2 V breakdown range (VBR at 1 mA), 600 W peak pulse power (10/1000 µs), clamping voltage of 93.6 V at 6.4 A, and operates across –55 °C to +150 °C junction temperature.
For engineers reviewing the SMBJ58CAHE3_A/H datasheet, SMBJ58CAHE3_A/H pinout, SMBJ58CAHE3_A/H application, or SMBJ58CAHE3_A/H equivalent, this device is selected for high-reliability transient suppression on DC power rails, signal lines, and automotive ECUs where bidirectional surge immunity, AEC-Q101 qualification, and low clamping ratio are critical.
Technical Context
This bidirectional TVS operates symmetrically in both polarities, with identical electrical characteristics forward and reverse - enabling protection against voltage transients regardless of polarity. Its glass-passivated junction ensures stable breakdown behavior, while low incremental surge resistance (Rdyn) supports consistent clamping under repetitive surges.
The device complies with ANSI/IEEE C62.35 standards for surge protection devices and meets J-STD-020 MSL Level 1 (260 °C reflow peak), making it suitable for automated SMT assembly without moisture sensitivity concerns. Its thermal resistance (RθJA = 100 °C/W) reflects standard SMB footprint thermal performance on 5.0 mm × 5.0 mm copper pads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 58 V - maximum continuous reverse operating voltage before conduction begins; defines safe DC/AC working limit |
| VBR (min/max) | 64.4 V / 71.2 V at 1 mA - guaranteed breakdown onset range; ensures predictable turn-on during transients |
| VC @ IPPM | 93.6 V at 6.4 A - clamped voltage during 600 W 10/1000 µs surge; determines protected circuit's max stress level |
| PPPM | 600 W - peak pulse power handling per single 10/1000 µs waveform; defines transient energy absorption capacity |
| IPPM | 6.4 A - peak pulse current corresponding to 600 W clamping; used for PCB trace sizing and layout margining |
| TJ max | +150 °C - maximum junction temperature; enables operation in under-hood automotive or industrial environments |

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-E3/52 | Same electrical specs and SMB package; commercial-grade (non-AEC-Q101), RoHS-compliant only | Lacks automotive qualification; suitable for industrial/commercial designs without automotive lifecycle or reliability mandates | Select SMBJ58CAHE3_A/H when AEC-Q101 compliance and extended temperature validation are required. |
| SMCJ58CAHE3_A/H | Same VWM, VBR, and bidirectional function but in larger SMC (DO-214AB) package with 1500 W PPPM | Higher surge rating supports harsher environments (e.g., railway, heavy machinery); requires larger PCB area | Choose SMBJ58CAHE3_A/H for space-constrained layouts where 600 W suffices; upgrade to SMCJ58CAHE3_A/H for >1 kV surge margins. |

FAQ
What does the "CA" suffix indicate in SMBJ58CAHE3_A/H?
The "CA" suffix denotes a bidirectional configuration - meaning SMBJ58CAHE3_A/H conducts and clamps symmetrically in both voltage polarities. Unlike unidirectional "A" variants, it has no cathode band marking and provides identical VBR, VC, and IPPM characteristics in either direction, making it ideal for AC-coupled or polarity-agnostic protection circuits.
Is SMBJ58CAHE3_A/H suitable for IEC 61000-4-5 surge testing?
Yes - SMBJ58CAHE3_A/H delivers 600 W peak pulse power with a 10/1000 µs waveform, which aligns with IEC 61000-4-5 Level 4 (4 kV) open-circuit voltage requirements when properly mounted on 5.0 mm × 5.0 mm copper pads. Its 93.6 V clamping voltage ensures protected circuitry remains within safe operating limits during standardized surge events.
How does the HE3 suffix differ from E3 in Vishay SMBJ part numbering?
The "HE3" suffix in SMBJ58CAHE3_A/H indicates RoHS-compliant construction plus AEC-Q101 qualification - verified for automotive use with extended temperature cycling, high-temperature reverse bias, and ESD robustness testing. In contrast, "E3" denotes RoHS compliance only, without automotive qualification or associated reliability validation.
What is the maximum allowable PCB trace length between SMBJ58CAHE3_A/H and the protected IC?
To maintain effective clamping, PCB traces from SMBJ58CAHE3_A/H to the protected node should be kept as short and wide as possible - ideally ≤ 5 mm in length and ≥ 0.5 mm in width. Longer or narrower traces add inductance that increases voltage overshoot during fast transients, potentially exceeding the 93.6 V clamping limit of SMBJ58CAHE3_A/H and compromising protection integrity.
Does SMBJ58CAHE3_A/H require a heatsink for continuous operation?
No - SMBJ58CAHE3_A/H is rated for 5.0 W steady-state power dissipation on an infinite heatsink at 50 °C ambient, but its primary function is transient suppression, not continuous power handling. Under normal operation, it draws negligible leakage current (<1 µA at 58 V). Heatsinking is unnecessary unless subjected to frequent repetitive surges exceeding duty cycle limits defined in Figure 2 of the datasheet.
