Product details
Overview
SMCJ58CAHM3_A/I from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMC (DO-214AB) 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), 1500 W peak pulse power (10/1000 µs), and clamps to ≤93.6 V at 16.0 A peak surge current - ideal for automotive sensor line and industrial I/O port protection.
For engineers reviewing the SMCJ58CAHM3_A/I datasheet, SMCJ58CAHM3_A/I pinout, SMCJ58CAHM3_A/I application, or SMCJ58CAHM3_A/I equivalent, key selection criteria include bidirectional clamping symmetry, AEC-Q101 qualification status, halogen-free RoHS compliance (HM3 suffix), and thermal resistance (RθJA = 75 °C/W) under standard PCB pad layout.
Technical Context
This device operates as a voltage-clamping protector with symmetrical reverse/forward conduction behavior due to its bidirectional construction. Its glass-passivated junction enables fast response (<1 ns), low incremental surge resistance, and stable clamping across temperature (tempco = 0.104 %/°C).
Rated for -55 °C to +150 °C junction operation, it meets MSL Level 1 per J-STD-020 and supports automated SMT placement. The SMC package provides mechanical robustness and UL 94 V-0 flammability rating, with matte tin-plated leads compliant to J-STD-002 and JESD 22-B102.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 58 V - maximum continuous reverse operating voltage before clamping begins |
| VBR (min/max) | 64.4 V / 71.2 V at 1.0 mA - guaranteed breakdown threshold range defining turn-on consistency |
| VC @ IPPM | ≤93.6 V at 16.0 A - clamped voltage during full 1500 W transient, limiting downstream stress |
| PPPM | 1500 W (10/1000 µs waveform) - surge energy handling capacity for lightning/inductive spike suppression |
| IPPM | 16.0 A - peak surge current corresponding to rated clamping voltage and power |
| TJ max | +150 °C - maximum junction temperature enabling use in under-hood automotive environments |
| RθJA | 75 °C/W - thermal resistance from junction to ambient on standard 8 mm × 8 mm copper pads |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, bidirectional - no polarity marking; symmetrical terminal configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry (reverse bias) | One side of bidirectional junction; conducts during negative transients relative to cathode reference |
| Cathode | Transient current entry (forward bias) | Other side of bidirectional junction; conducts during positive transients - functionally identical to anode in CA devices |

Applications
| Automotive Sensor Protection | Industrial I/O Port Protection |
|---|---|
Use Scenario: Protecting CAN/LIN bus lines and analog sensor inputs (e.g., pressure, temperature) from load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Voltage-clamping TVS placed directly at connector interface to shunt surge energy before reaching signal conditioning ICs. Use Value: Maintains signal integrity by clamping transients to ≤93.6 V while surviving repeated 1500 W surges - critical for AEC-Q100-compliant ECUs. | Use Scenario: Safeguarding PLC digital input modules and RS-485 transceivers against field-wiring induced surges and ESD events. IC Role / Device Role / Timing Role: Primary overvoltage clamp on unshielded field-side traces, coordinated with upstream series impedance. Use Value: Enables >10000 surge cycles at rated conditions without parameter drift, supporting 15+ year industrial deployment lifetimes. |
| Power Supply Rail Clamp | Consumer Device USB/DC Jack Protection |
Use Scenario: Secondary protection on 12 V/24 V DC input rails after primary fuse and common-mode choke filtering. IC Role / Device Role / Timing Role: Fast-acting shunt element that activates within nanoseconds to limit rail overshoot during hot-swap or back-EMF events. Use Value: Prevents latch-up or burnout in downstream DC-DC controllers by holding rail voltage below 95 V during 10/1000 µs transients. | Use Scenario: Input-stage surge suppression for wall adapters and USB-C PD ports exposed to user-handling ESD and accidental AC mains contact. IC Role / Device Role / Timing Role: Bidirectional clamping device placed between VBUS and GND to absorb ±15 kV contact ESD per IEC 61000-4-2. Use Value: Delivers consistent clamping performance across polarity reversals - essential for reversible USB connectors and universal adapters. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAC58CA | Same VWM/VC specs but lower PPPM (600 W); SOD-123FL package, smaller footprint | Limited to lower-energy transients; unsuitable for ISO 7637-2 Pulse 5a simulation | Select when board space is constrained and surge threat level is limited to IEC 61000-4-5 Level 3 (0.5 kV) |
| SMCJ58AHE3_A/I | Unidirectional version with cathode band marking; otherwise identical electrical specs and HM3 halogen-free compliance | Requires correct polarity orientation; not suitable for AC-coupled or floating signal lines | Choose only when circuit topology guarantees fixed polarity and grounding scheme permits unidirectional clamping |
Compared with SAC58CA and SMCJ58AHE3_A/I, the SMCJ58CAHM3_A/I uniquely combines bidirectional symmetry, 1500 W surge rating, AEC-Q101 qualification, and halogen-free construction - making it the preferred choice for high-reliability automotive and industrial DC power and data line protection where polarity uncertainty or high-energy threats exist.

FAQ
What does the "CA" suffix indicate in SMCJ58CAHM3_A/I?
The "CA" suffix denotes a bidirectional configuration - meaning the SMCJ58CAHM3_A/I provides symmetrical clamping for both positive and negative voltage transients without polarity dependence. Unlike unidirectional variants (e.g., SMCJ58A), it has no cathode band marking and functions identically in either orientation, making it ideal for AC-coupled or floating signal paths where voltage polarity cannot be guaranteed.
Is SMCJ58CAHM3_A/I qualified for automotive applications?
Yes, SMCJ58CAHM3_A/I is AEC-Q101 qualified, as confirmed by Vishay's ordering code structure (HM3 suffix with "_A" revision). This qualification covers stress tests including high-temperature reverse bias, temperature cycling, and ESD, validating its suitability for under-hood and chassis-mounted automotive electronics such as body control modules and ADAS sensor interfaces.
How does the HM3 suffix differ from E3 or M3 in SMCJ58CAHM3_A/I?
The HM3 suffix in SMCJ58CAHM3_A/I specifies halogen-free, RoHS-compliant construction with AEC-Q101 qualification - distinguishing it from E3 (RoHS-compliant commercial grade) and M3 (halogen-free RoHS-compliant commercial grade). Only HM3 and HE3 variants carry automotive qualification; HM3 adds halogen-free chemistry while retaining the same SMC package dimensions and electrical performance as E3/M3 counterparts.
What is the maximum clamping voltage of SMCJ58CAHM3_A/I at rated surge current?
The maximum clamping voltage (VC) of SMCJ58CAHM3_A/I is 93.6 V at its rated peak pulse current (IPPM) of 16.0 A, measured under the standardized 10/1000 µs double-exponential waveform. This value is guaranteed across the full operating temperature range (-55 °C to +150 °C) and defines the upper voltage limit imposed on protected circuits during worst-case surge events.
Can SMCJ58CAHM3_A/I be used in place of a unidirectional TVS like SMCJ58AHE3_A/I?
SMCJ58CAHM3_A/I can replace SMCJ58AHE3_A/I only if the circuit allows bidirectional clamping and does not rely on polarity-dependent forward conduction. While both share identical VWM, VBR, and PPPM, the unidirectional part requires correct cathode orientation and offers slightly lower leakage in forward bias. Substitution without layout review risks improper protection on polarized rails or misaligned ground references.
