Product details
Overview
SMBJ58CA-M3/52 from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on signal or power lines. It features a 58 V standoff voltage (VWM), 64.4–71.2 V breakdown range (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 signal lines in industrial and telecom equipment.
For engineers reviewing the SMBJ58CA-M3/52 datasheet, SMBJ58CA-M3/52 pinout, SMBJ58CA-M3/52 application, or SMBJ58CA-M3/52 equivalent, this device is selected for robust ESD and surge protection where bidirectional clamping, low leakage (<1 µA at VWM), and AEC-Q101 qualification readiness are required in space-constrained PCB layouts.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, with identical electrical characteristics in forward and reverse directions. Its glass-passivated junction ensures stable breakdown behavior and fast response time (<1 ns), while the low incremental surge resistance enables effective energy diversion during transient events.
The device is rated for 150 °C maximum junction temperature and exhibits a typical thermal resistance of 100 °C/W (junction-to-ambient) on standard 0.2" × 0.2" copper pads. Its M3 suffix denotes halogen-free, RoHS-compliant construction with matte tin-plated leads meeting J-STD-002 solderability standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 58 V - Maximum continuous reverse voltage before significant leakage; defines operating margin below clamping threshold |
| VBR (Breakdown Voltage) | 64.4–71.2 V at 1 mA - Confirmed breakdown range ensuring reliable turn-on during overvoltage events |
| VC (Clamping Voltage) | 93.6 V at IPPM = 6.4 A - Peak voltage seen by protected circuit during 600 W transient; critical for downstream component survivability |
| PPPM (Peak Pulse Power) | 600 W with 10/1000 µs waveform - Sustains high-energy surges without failure under defined test conditions |
| IPPM (Peak Pulse Current) | 6.4 A - Maximum non-repetitive surge current the device safely clamps; determines protection level against lightning or inductive spikes |
| ID (Reverse Leakage) | <1 µA at 58 V - Negligible standby power loss and minimal interference with high-impedance signal paths |
| TJmax | 150 °C - Enables operation in harsh environments including industrial motor drives and outdoor telecom enclosures |

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; RoHS-compliant but not halogen-free; uses standard tin-lead compatible plating | Preferred for commercial-grade assemblies where halogen-free requirement is not mandated | Select when cost-sensitive production requires legacy-compatible finish without halogen restrictions |
| SMBJ58CAHM3_52 | Identical M3 halogen-free construction; adds AEC-Q101 qualification and enhanced traceability (HM3 suffix) | Required for automotive ECUs needing PPAP documentation and extended temperature validation | Choose for automotive body electronics requiring certified reliability and full lifecycle traceability |
Compared with SMBJ58CA-M3/52, the E3 variant offers lower procurement cost for non-automotive use, while the HM3 variant provides documented AEC-Q101 qualification for safety-critical vehicle systems - neither is pin-compatible in the sense of guaranteed drop-in replacement without review of qualification status and sourcing chain.

FAQ
What is the clamping voltage of SMBJ58CA-M3/52 at its rated peak pulse current?
The SMBJ58CA-M3/52 has a maximum clamping voltage (VC) of 93.6 V at 6.4 A peak pulse current (IPPM) under 10/1000 µs waveform conditions. This value is measured per JEDEC standards and defines the upper voltage limit imposed on protected circuits during surge events. The SMBJ58CA-M3/52 maintains this clamping performance across its full operating temperature range.
Is SMBJ58CA-M3/52 suitable for bidirectional signal line protection?
Yes - SMBJ58CA-M3/52 is explicitly designed as a bidirectional TVS diode, with identical breakdown and clamping characteristics in both polarities. Its unmarked SMB package allows placement without orientation concerns on AC-coupled or floating differential lines such as RS-485, CAN, or audio interfaces. The SMBJ58CA-M3/52 delivers symmetrical protection without requiring external polarity management.
Does SMBJ58CA-M3/52 meet automotive qualification standards?
The SMBJ58CA-M3/52 itself is not AEC-Q101 qualified; it carries the M3 halogen-free, RoHS-compliant designation for commercial-grade use. For automotive applications, Vishay offers the SMBJ58CAHM3_52 variant, which adds AEC-Q101 qualification and full PPAP support. Engineers must specify SMBJ58CAHM3_52 - not SMBJ58CA-M3/52 - when automotive qualification is mandatory.
What is the thermal resistance of SMBJ58CA-M3/52 in standard mounting conditions?
The SMBJ58CA-M3/52 exhibits 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 FR-4 PCB with no additional heatsinking. Derating is required above 25 °C ambient, with full power capability maintained only up to 50 °C ambient per the datasheet's thermal curves.
How does the M3 suffix affect the construction and compliance of SMBJ58CA-M3/52?
The M3 suffix on SMBJ58CA-M3/52 indicates halogen-free, RoHS-compliant construction using bromine- and chlorine-free molding compounds and matte tin-plated leads. It meets JESD 201 Class 2 whisker resistance and J-STD-002 solderability requirements. Unlike the E3 variant, SMBJ58CA-M3/52 avoids all restricted halogens while retaining identical electrical performance and package dimensions.
