Overview
SMCJ58CAHE3/57T from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) in SMC (DO-214AB) package, designed for clamping voltage transients up to 1500 W peak pulse power with 93.6 V clamping voltage at 16.0 A peak surge current and 58 V standoff voltage. It features glass-passivated junction, AEC-Q101 qualification, and is used for protecting automotive sensor signal lines, industrial I/O ports, and power supply rails against ESD and inductive switching surges.
For engineers reviewing the SMCJ58CAHE3/57T datasheet, SMCJ58CAHE3/57T pinout, SMCJ58CAHE3/57T application, or SMCJ58CAHE3/57T equivalent, this page delivers verified electrical specs, thermal derating behavior, bidirectional clamping performance, AEC-Q101 compliance status, and direct alternatives for automotive-grade transient protection design.
Technical Context
The SMCJ58CAHE3/57T operates as a bidirectional avalanche diode with symmetrical breakdown characteristics - minimum VBR = 64.4 V and maximum VBR = 71.2 V at 1.0 mA test current, and clamps to ≤93.6 V at 16.0 A (10/1000 µs waveform). Its low incremental surge resistance enables fast response (<1 ns) and stable clamping under repetitive transients.
Thermally, it exhibits RθJA = 75 °C/W (on recommended 8.0 mm × 8.0 mm copper pads) and RθJL = 15 °C/W, supporting operation from –55 °C to +150 °C junction temperature. The device meets MSL Level 1 per J-STD-020 and passes JESD201 Class 2 whisker testing.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Pinout & Package
SMCJ58CAHE3/57T uses the SMC (DO-214AB) package: a two-terminal, bidirectional device with no polarity marking. Both terminals are electrically symmetrical; neither is designated anode or cathode. Leads are matte tin-plated and solderable per J-STD-002 and JESD22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 | Bidirectional Surge Path | Connects to protected line (e.g., CAN_H or LIN bus); conducts surge current equally in either direction during overvoltage events. |
| Terminal 2 | Bidirectional Surge Path | Connects to reference plane (e.g., chassis ground or power return); completes low-impedance path for transient energy dissipation. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive under-hood use - supports long-term reliability in high-temperature, high-vibration environments without derating penalties. |
| 1500 W peak pulse power | Handles IEC 61000-4-5 Level 4 surges (4 kV, 2 Ω source) on 48 V buses without failure; eliminates need for external series impedance in many cases. |
| Low clamping ratio (VC/VWM ≈ 1.61) | Minimizes overvoltage stress on downstream components - critical for safeguarding 75 V-rated CAN transceivers and microcontrollers. |
| MSL Level 1 rating | Enables standard reflow assembly without moisture sensitivity concerns - no baking required prior to PCB mounting. |
| Glass-passivated junction | Ensures stable VBR over lifetime and immunity to humidity-induced parameter drift - essential for industrial field deployments. |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |

| Telecom Power Rail Protection | Motor Drive Gate Driver Protection |
|
Use Scenario: Shielding 48 V PoE-powered Ethernet switch power inputs from lightning-induced surges on outdoor cabling. IC Role / Device Role / Timing Role: Primary-level TVS on DC input rail upstream of DC/DC converter, clamping common-mode transients before isolation barrier. Use Value: Meets GR-1089-CORE Level 3 surge immunity; avoids catastrophic failure of primary-side MOSFETs and controller ICs. |
Use Scenario: Protecting high-side and low-side gate driver ICs in BLDC inverters from Miller-induced voltage spikes during fast IGBT/MOSFET switching. IC Role / Device Role / Timing Role: Localized TVS across gate-to-source terminals of power devices, suppressing dv/dt-induced false turn-on.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ58AHE3/A | Unidirectional; lower PPPM = 400 W; same VWM = 58 V but asymmetric clamping (no negative-polarity protection). | Only suitable where polarity is fixed and surge direction is known (e.g., DC power input with defined ground reference). | Select only if circuit topology guarantees unidirectional transients and power handling <400 W suffices. |
| SMCJ58AHE3/57T | Unidirectional variant; identical package and thermal specs, but lacks bidirectional symmetry - VBR defined only for cathode-to-anode polarity. | Applicable in single-rail DC systems with explicit cathode grounding; cannot protect AC-coupled or floating signal paths. | Choose when cost optimization is prioritized and bidirectional clamping is not required - e.g., 12 V battery feed protection. |
Compared with SMCJ58CAHE3/57T, SMAJ58AHE3/A offers lower surge capacity and unidirectional operation, while SMCJ58AHE3/57T provides identical mechanical fit but no negative-polarity clamping - making the CA variant uniquely suited for bidirectional data lines and floating sensors.

FAQ
What is the clamping voltage of SMCJ58CAHE3/57T at its rated peak pulse current?
The SMCJ58CAHE3/57T clamps to a maximum of 93.6 V at 16.0 A peak pulse current under the standard 10/1000 µs waveform. This value is measured with the device mounted on 8.0 mm × 8.0 mm copper pads per JEDEC guidelines and defines the upper voltage limit imposed on protected circuits during surge events.
Is SMCJ58CAHE3/57T suitable for automotive applications?
Yes, SMCJ58CAHE3/57T is AEC-Q101 qualified - confirmed by Vishay's documentation and marked with the HE3 suffix. It supports full automotive temperature range (–55 °C to +150 °C), passes humidity and thermal cycling tests, and is widely deployed in engine control modules, ADAS sensor interfaces, and body electronics.
How does the bidirectional nature of SMCJ58CAHE3/57T affect its circuit placement?
Because SMCJ58CAHE3/57T is bidirectional, it has no polarity marking and can be placed across any two nodes requiring symmetrical overvoltage protection - such as differential signal pairs (CAN_H/CAN_L), AC-coupled lines, or floating sensor outputs. No orientation check is needed during layout or assembly.
What is the thermal resistance of SMCJ58CAHE3/57T, and how does it impact PCB layout?
The SMCJ58CAHE3/57T has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on the recommended 8.0 mm × 8.0 mm copper pad per terminal. To maintain reliability under repeated surges, PCB layout must replicate this pad area - undersized pads cause excessive junction heating and premature degradation.
Does SMCJ58CAHE3/57T require special handling or moisture precautions before soldering?
No - SMCJ58CAHE3/57T is rated MSL Level 1 per J-STD-020, meaning it may be stored indefinitely at ambient conditions and subjected to standard lead-free reflow profiles (peak 260 °C) without baking or dry-pack requirements. Its matte tin-plated leads comply with J-STD-002 for solderability.
