Product details
Overview
SMCJ58AHM3/H from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for robust overvoltage protection of DC power rails and signal lines. It features a 58 V standoff voltage (VWM), 64.4–71.2 V breakdown voltage (VBR) at 1 mA, 93.6 V maximum clamping voltage (VC) at 16 A peak pulse current, and 1500 W peak pulse power rating with 10/1000 µs waveform - used in automotive power supply input stages and industrial sensor interfaces.
For engineers reviewing the SMCJ58AHM3/H datasheet, SMCJ58AHM3/H pinout, SMCJ58AHM3/H application, or SMCJ58AHM3/H equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance (RθJA = 75 °C/W), junction temperature range (–55 to +150 °C), and halogen-free RoHS-compliant construction per JESD201 Class 2 whisker test.
Technical Context
The SMCJ58AHM3/H operates as a unidirectional avalanche diode, clamping transients above its breakdown threshold while maintaining low leakage (<1 µA at 58 V). Its glass-passivated junction ensures stable VBR tolerance (±5%) and fast response time (<1 ns), enabling effective suppression of ESD, lightning-induced surges, and inductive switching spikes.
Designed for surface-mount assembly on 8.0 mm × 8.0 mm copper pads, it meets MSL Level 1 per J-STD-020 (peak reflow 260 °C) and supports automated placement. The cathode band denotes polarity; no marking is used for bidirectional variants - but SMCJ58AHM3/H is explicitly unidirectional per ordering code suffix "A" and marking code "GGG".
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 58 V - maximum continuous reverse operating voltage before clamping begins; defines safe DC rail margin for 48 V systems. |
| VBR min/max | 64.4 V / 71.2 V at IT = 1 mA - tight breakdown window ensures predictable turn-on across temperature and unit variation. |
| VC @ IPPM | 93.6 V at 16 A - clamping voltage under 10/1000 µs surge; limits downstream IC stress during 1500 W transient events. |
| PPPM | 1500 W - peak pulse power handling capability; enables protection against IEC 61000-4-5 Level 4 surges (4 kV/2 Ω). |
| TJ max | +150 °C - maximum junction temperature; supports operation in under-hood automotive environments and sealed industrial enclosures. |
| RθJA | 75 °C/W - thermal resistance junction-to-ambient on standard PCB layout; informs derating above 25 °C ambient. |
| Package | SMC (DO-214AB) - industry-standard 2-pin surface-mount outline with 7.75 mm × 6.22 mm footprint and 2.62 mm height. |
Pinout & Package
SMCJ58AHM3/H uses the SMC (DO-214AB) package: a molded, halogen-free, RoHS-compliant surface-mount case with matte tin-plated leads solderable per J-STD-002. Polarity is marked by a cathode band on the body end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to ground or low-potential node; completes clamping path when transient exceeds VBR. |
| Cathode | High-side protected node | Connected to line being protected (e.g., 48 V rail); band-marked end; reverse-biased during normal operation. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing - required for engine control, ADAS, and infotainment power rails. |
| Halogen-free & RoHS-compliant | HM3 suffix confirms compliance with JEDEC J-STD-201 Class 2 whisker resistance and EU RoHS Directive 2011/65/EU - suitable for green manufacturing. |
| Low incremental surge resistance | Enables tighter VC/VBR ratio (93.6 V / 64.4 V ≈ 1.45), minimizing let-through energy during fast transients compared to higher-ratio TVS devices. |
| MSL Level 1 moisture sensitivity | Allows unlimited floor life and standard reflow without baking - simplifies SMT line integration and reduces production risk. |
| Glass passivated junction | Ensures long-term stability of VBR and leakage performance across humidity, bias, and thermal stress - critical for 15-year automotive service life. |
Applications
| Automotive Power Input Protection | Industrial Sensor Signal Line Protection |
|---|---|
Use Scenario: 48 V battery-fed ECUs exposed to load dump (ISO 16750-2) and alternator ripple. IC Role / Device Role / Timing Role: Unidirectional TVS placed between input rail and chassis ground to clamp surges up to 1500 W. Use Value: Limits peak voltage to ≤93.6 V during 10/1000 µs transients, protecting downstream DC/DC converters and microcontrollers rated for 65 V absolute maximum. | Use Scenario: Analog output lines from pressure/temperature sensors in factory automation PLC modules. IC Role / Device Role / Timing Role: Point-of-entry TVS on 0–10 V or 4–20 mA signal paths to suppress ESD and field-wiring induced noise. Use Value: Sub-1 ns response prevents latch-up in precision op-amps and ADC front-ends; <1 µA leakage avoids measurement offset errors at 58 V standoff. |
| Telecom DC Power Feeds | Motor Drive Gate Driver Protection |
Use Scenario: -48 V telecom rectifier outputs feeding base station RF amplifiers and backhaul interfaces. IC Role / Device Role / Timing Role: Primary overvoltage clamp on secondary-side distribution bus, coordinated with upstream fuses. Use Value: Withstands repeated 1500 W surges without degradation; RθJA = 75 °C/W allows thermal design margin in confined 1RU chassis. | Use Scenario: Isolated gate drive supply rails (e.g., 15 V) for SiC MOSFET half-bridges in servo inverters. IC Role / Device Role / Timing Role: Fast-clamping TVS across gate driver VDD-GND to suppress Miller-induced spikes and shoot-through transients. Use Value: 93.6 V clamping ensures gate oxide safety margin even during 100 V+ dV/dt events; unidirectional configuration avoids forward conduction during normal PWM. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ58A-E3/57T | Lower PPPM (400 W), smaller SMA package (DO-214AC), higher RθJA (110 °C/W) | Not suitable for 1500 W IEC 61000-4-5 Level 4; limited to lower-energy surges in space-constrained consumer designs | Select only if system-level surge testing confirms <400 W requirement and PCB layout cannot accommodate SMC footprint. |
| SMCJ58AHE3_A/H | Same electrical specs and SMC package, but RoHS-compliant commercial grade (E3) instead of halogen-free (HM3); no AEC-Q101 qualification | Lacks automotive qualification; acceptable for industrial/commercial power supplies where AEC-Q101 is not mandated | Choose for cost-sensitive non-automotive applications where halogen-free is not required and AEC-Q101 is unnecessary. |
Compared with SMAJ58A-E3/57T and SMCJ58AHE3_A/H, the SMCJ58AHM3/H uniquely combines 1500 W surge capability, AEC-Q101 qualification, and halogen-free construction - making it the only option qualified for high-reliability automotive power domains requiring both robustness and regulatory compliance.

FAQ
What is the maximum clamping voltage of the SMCJ58AHM3/H under a 10/1000 µs surge?
The SMCJ58AHM3/H has a maximum clamping voltage (VC) of 93.6 V at 16 A peak pulse current with a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and confirmed in Vishay's Document Number 88394, ensuring predictable overvoltage limiting during standardized surge events. The SMCJ58AHM3/H maintains this clamping performance across its full operating temperature range.
Is the SMCJ58AHM3/H qualified for automotive applications?
Yes, the SMCJ58AHM3/H carries the HM3 suffix, indicating halogen-free, RoHS-compliant, and AEC-Q101 qualified construction. It undergoes rigorous stress testing including temperature cycling, highly accelerated life testing (HALT), and ESD per AEC-Q101 Rev D. This makes the SMCJ58AHM3/H suitable for under-hood and cabin electronics where automotive-grade reliability is mandatory.
What does the "HM3" suffix mean in SMCJ58AHM3/H?
The "HM3" suffix in SMCJ58AHM3/H denotes halogen-free, RoHS-compliant, and AEC-Q101 qualified construction per Vishay's ordering nomenclature. It distinguishes this variant from commercial-grade E3 versions and confirms compliance with JESD201 Class 2 whisker resistance, UL 94 V-0 flammability, and automotive qualification requirements - all verified in the official datasheet (Doc. #88394).
Can the SMCJ58AHM3/H replace the SMCJ58AHE3_A/H in an existing design?
The SMCJ58AHM3/H is a direct functional replacement for SMCJ58AHE3_A/H in terms of electrical specs and package, but adds halogen-free materials and AEC-Q101 qualification. No PCB changes are needed due to identical SMC (DO-214AB) footprint and pinout. However, the SMCJ58AHM3/H should be selected specifically when automotive qualification or halogen-free compliance is required - otherwise SMCJ58AHE3_A/H remains valid for commercial use.
What is the thermal resistance junction-to-ambient for SMCJ58AHM3/H?
The SMCJ58AHM3/H has a typical thermal resistance junction-to-ambient (RθJA) of 75 °C/W when mounted on the minimum recommended pad layout (0.31" × 0.31" copper pads per terminal). This value is specified in Vishay's datasheet (Document Number 88394, page 3) and is critical for derating power dissipation above 25 °C ambient temperature - especially in enclosed automotive or industrial enclosures.
