Product details
Overview
SMBJ58CHE3/52 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 DC power rails 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 - deployed in automotive ECUs, industrial I/O modules, and telecom power supplies.
For engineers reviewing the SMBJ58CHE3/52 datasheet, SMBJ58CHE3/52 pinout, SMBJ58CHE3/52 application, or SMBJ58CHE3/52 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 production-grade surge protection design.
Technical Context
This TVS diode operates as a unidirectional clamping device: reverse-biased during normal operation, it remains high-impedance until transient voltage exceeds VBR, then rapidly switches to low-impedance state to shunt surge current away from protected circuitry. Its glass-passivated junction ensures stable breakdown characteristics and long-term reliability under repetitive transients.
Designed for 10/1000 µs surge waveforms per ANSI/IEEE C62.35, SMBJ58CHE3/52 delivers 6.4 A peak pulse current (IPPM) while limiting clamped voltage to ≤93.6 V. With 0.057 %/°C VBR temperature coefficient and MSL Level 1 moisture sensitivity, it supports automated SMT assembly and high-reliability automotive environments.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ58AHE3/52 | No AEC-Q101 qualification; identical electrical specs and package. | Restricted to commercial/industrial use; not approved for automotive OEM designs. | Select SMBJ58AHE3/52 only if AEC-Q101 compliance is not required and cost optimization is prioritized. |
| SAC58 | Same VWM (58 V) but lower PPPM (400 W); DO-214AB (SMC) package, larger footprint. | Lower surge capacity suits less demanding environments; larger package eases manual repair but increases board area. | Choose SAC58 where space allows and 400 W surge rating suffices - e.g., consumer-grade power adapters. |
Compared with SMBJ58AHE3/52, SMBJ58CHE3/52 adds AEC-Q101 validation for automotive deployment without electrical trade-offs; versus SAC58, it delivers 50 % higher surge power in a 30 % smaller SMB footprint, enabling compact, high-reliability designs.

FAQ
What is the clamping voltage of SMBJ58CHE3/52 at its rated peak pulse current?
The SMBJ58CHE3/52 has a maximum clamping voltage (VC) of 93.6 V at 6.4 A peak pulse current (IPPM) with a 10/1000 µs waveform. This value is measured under standardized test conditions and defines the upper voltage limit imposed on protected circuitry during a 600 W transient event. The SMBJ58CHE3/52 maintains this clamping performance across its qualified operating temperature range.
Is SMBJ58CHE3/52 qualified for automotive applications?
Yes, SMBJ58CHE3/52 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, humidity bias, and mechanical shock - validating its suitability for under-hood and chassis-mounted automotive electronics. The SMBJ58CHE3/52 meets automotive reliability requirements without derating.
What is the thermal resistance of SMBJ58CHE3/52, and how does it affect layout?
The SMBJ58CHE3/52 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 value assumes standard PCB layout; reducing pad size or omitting thermal vias increases RθJA, requiring derating of power dissipation above 25 °C ambient. For sustained operation near TJ max (150 °C), SMBJ58CHE3/52 needs ≥1 cm² total copper area per pad.
Does SMBJ58CHE3/52 have polarity marking, and how is it identified?
Yes, SMBJ58CHE3/52 is unidirectional and features a visible cathode band on the package body - located at the cathode terminal end. This marking aligns with the DO-214AA outline and must be oriented toward the protected line (e.g., 48 V rail), while the anode connects to ground or return. Incorrect orientation renders the device ineffective for reverse-transient suppression.
What surge waveform standard does SMBJ58CHE3/52 meet, and what is its peak pulse current?
SMBJ58CHE3/52 is rated for the 10/1000 µs double-exponential surge waveform defined in ANSI/IEEE C62.35 and IEC 61000-4-5. At this waveform, its peak pulse current (IPPM) is 6.4 A, corresponding to the 600 W peak pulse power rating. This rating is validated with derating above 25 °C ambient per Figure 2 in datasheet 88392, and applies to single, non-repetitive events.
