Product details
Overview
SMCJ58AHM3_A/H from Vishay General Semiconductor is a unidirectional 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 range (VBR at 1 mA), 93.6 V clamping voltage at 16 A peak pulse current (10/1000 µs), and 1500 W peak pulse power rating. It is halogen-free, RoHS-compliant, and qualified to AEC-Q101 for automotive-grade reliability.
For engineers reviewing the SMCJ58AHM3_A/H datasheet, SMCJ58AHM3_A/H pinout, SMCJ58AHM3_A/H application, or SMCJ58AHM3_A/H equivalent, key selection criteria include clamping performance under 10/1000 µs surge, thermal resistance (RθJA = 75 °C/W), junction temperature limit (TJ max = 150 °C), unidirectional polarity marking, and compatibility with automated SMT placement on 8.0 mm × 8.0 mm copper pads.
Technical Context
The SMCJ58AHM3_A/H operates as a silicon avalanche diode that enters controlled breakdown above its reverse standoff voltage (VWM = 58 V), limiting transient voltages to ≤93.6 V at 16 A IPPM. Its glass-passivated junction ensures stable leakage (<1 µA at VWM) and fast response time (<1 ns), critical for protecting sensitive MOSFET gates and microcontroller I/Os.
Designed for surface-mount use in high-energy surge environments, it meets MSL Level 1 per J-STD-020 (peak reflow 260 °C), supports 200 A non-repetitive forward surge (IFSM), and delivers low incremental surge resistance - enabling effective suppression of inductive switching spikes and lightning-induced transients in automotive and industrial systems.

IC Role / Device Role / Timing Role: TVS mounted at connector entry point, shunting EFT (IEC 61000-4-4) and surge (IEC 61000-4-5) energy away from precision op-amps and ADCs. Use Value: Sub-1 ns response ensures clamping initiates before transient edge propagates into signal chain, preserving measurement integrity. |
| DC Motor Drive Gate Protection | Telecom Power Supply Input Protection |
Use Scenario: Shielding high-side N-channel MOSFET gates from inductive kickback during PWM commutation in BLDC drivers. IC Role / Device Role / Timing Role: TVS placed between gate and source, clamping negative-going spikes induced by rapid dV/dt across motor windings. Use Value: 200 A IFSM rating withstands repetitive gate drive surges; 1500 W PPPM handles worst-case flyback energy without degradation. | Use Scenario: Front-end protection of 48 V telecom rectifier outputs against lightning-induced surges entering via distribution lines. IC Role / Device Role / Timing Role: Primary unidirectional TVS on +48 V bus, coordinated with upstream MOVs and downstream polyfuses for staged overvoltage defense. Use Value: 93.6 V clamping ensures downstream DC-DC converters (rated 60 V input max) remain within absolute maximum ratings during 4 kV surge events. |
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), no AEC-Q101 qualification. | Limited to low-energy consumer electronics; unsuitable for automotive or industrial surge testing. | Select only for space-constrained, cost-sensitive designs where 1500 W surge immunity is not required. |
| SMCJ58AHE3_A/H | Same electrical specs and SMC package, but RoHS-compliant commercial grade (not halogen-free); lacks AEC-Q101 qualification. | Acceptable for non-automotive industrial use; may not meet OEM automotive material compliance requirements. | Choose when halogen-free content is not mandated and AEC-Q101 is unnecessary for the target application. |
Compared with SMAJ58A-E3/57T and SMCJ58AHE3_A/H, the SMCJ58AHM3_A/H provides superior surge robustness (1500 W vs. 400 W), lower thermal resistance (75 vs. 110 °C/W), halogen-free construction, and AEC-Q101 validation - making it the preferred choice for mission-critical automotive and industrial power rail protection where long-term reliability and regulatory compliance are mandatory.

FAQ
What is the clamping voltage of the SMCJ58AHM3_A/H at its rated peak pulse current?
The SMCJ58AHM3_A/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 under standardized test conditions and defines the upper voltage limit imposed on protected circuits during surge events. The SMCJ58AHM3_A/H maintains this clamping performance consistently due to its glass-passivated junction and low incremental surge resistance.
Is the SMCJ58AHM3_A/H suitable for automotive applications?
Yes, the SMCJ58AHM3_A/H is AEC-Q101 qualified and manufactured with halogen-free, RoHS-compliant materials - meeting stringent automotive reliability and environmental requirements. It is explicitly rated for operation from –55 °C to +150 °C junction temperature and validated for thermal cycling, mechanical shock, and humidity resistance. The SMCJ58AHM3_A/H is commonly deployed in engine control units, body electronics, and ADAS sensor modules.
How does the SMCJ58AHM3_A/H differ from the SMCJ58AHE3_A/H variant?
The SMCJ58AHM3_A/H and SMCJ58AHE3_A/H share identical electrical specifications and SMC (DO-214AB) packaging, but differ in material compliance: SMCJ58AHM3_A/H is halogen-free and AEC-Q101 qualified, whereas SMCJ58AHE3_A/H is RoHS-compliant commercial grade without halogen-free certification or automotive qualification. The SMCJ58AHM3_A/H is required for OEM automotive designs mandating both halogen-free content and AEC-Q101 validation.
What is the recommended PCB pad layout for optimal thermal performance of the SMCJ58AHM3_A/H?
Vishay specifies a minimum 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pad area for each terminal of the SMCJ58AHM3_A/H to achieve rated power dissipation and maintain RθJA = 75 °C/W. Use solid internal ground/power planes connected via multiple thermal vias to enhance heat spreading. Avoid narrow traces or isolated pads, as insufficient copper reduces surge current handling and accelerates thermal degradation during repeated transients.
Does the SMCJ58AHM3_A/H have polarity marking, and how is it identified?
Yes, the SMCJ58AHM3_A/H is unidirectional and features a visible cathode band on the device body - located adjacent to the cathode terminal. This band must be aligned toward the higher-potential side of the protected circuit (e.g., VBUS or signal line). The anode connects to the lower-potential reference (e.g., GND or return path). No marking appears on bidirectional variants, but the SMCJ58AHM3_A/H is strictly unidirectional and relies on this band for correct orientation during placement.
