Product details
Overview
SMCJ58HE3/57T from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-214AB (SMCJ) 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 (PPPM), and clamps transients to ≤93.6 V at 16 A, commonly used in automotive power line and industrial DC supply rail protection.
For engineers reviewing the SMCJ58HE3/57T datasheet, SMCJ58HE3/57T pinout, SMCJ58HE3/57T application, or SMCJ58HE3/57T equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 150 °C junction temperature rating, low incremental surge resistance, and compatibility with automated SMT assembly on 8 mm × 8 mm copper pads.
Technical Context
The SMCJ58HE3/57T operates as a silicon avalanche diode that enters breakdown when reverse voltage exceeds its VBR threshold, diverting surge current away from protected circuitry. Its glass-passivated junction ensures stable leakage and long-term reliability under repetitive transients.
It complies with ANSI/IEEE C62.35 for surge suppression and meets J-STD-020 MSL Level 1 with 260 °C lead-free reflow capability. The device is rated for 200 A non-repetitive forward surge (IFSM) and exhibits 75 °C/W junction-to-ambient thermal resistance on standard PCB pads.

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-E3/52T | Lower PPPM (400 W), SMA package (smaller footprint, higher RθJA) | Suitable only for lower-energy transients; not AEC-Q101 qualified | Select when board space is constrained and surge threat level is limited to IEC 61000-4-2 ±8 kV contact |
| 1.5SMC58A | Same DO-214AB package and 58 V VWM, but non-AEC-Q101, commercial-grade | Lacks automotive qualification; may require additional validation for automotive use | Choose for cost-sensitive industrial designs where AEC-Q101 is not mandated |
Compared with SMAJ58A-E3/52T and 1.5SMC58A, the SMCJ58HE3/57T delivers higher surge robustness (1500 W vs. 400 W or 1500 W), guaranteed AEC-Q101 qualification, and tighter VBR tolerance-making it the preferred choice for automotive and mission-critical industrial power rail protection.

FAQ
What is the polarity configuration of the SMCJ58HE3/57T?
The SMCJ58HE3/57T is a unidirectional transient voltage suppressor diode. Its cathode is marked by a band on the DO-214AB package, and it conducts in forward bias while clamping reverse transients above its breakdown voltage. This configuration is ideal for protecting DC power rails where polarity is fixed, such as automotive 12 V or industrial 48 V supplies.
Does the SMCJ58HE3/57T meet automotive qualification standards?
Yes, the SMCJ58HE3/57T is AEC-Q101 qualified, as confirmed in Vishay's official datasheet (Document Number: 88394). This qualification covers stress tests including temperature cycling, highly accelerated life testing (HALT), and surge robustness-ensuring suitability for under-hood and chassis-mounted automotive electronics.
What is the maximum clamping voltage of the SMCJ58HE3/57T under surge conditions?
The SMCJ58HE3/57T has a maximum clamping voltage (VC) of 93.6 V at 16 A peak pulse current (IPPM), tested with a 10/1000 μs waveform. This value defines the upper voltage limit imposed on protected circuitry during standardized surge events, ensuring compatibility with 100 V-rated downstream components.
How does the SMCJ58HE3/57T differ from bi-directional variants like SMCJ58CA?
The SMCJ58HE3/57T is unidirectional and intended for DC line protection with defined polarity; SMCJ58CA is bi-directional and suited for AC or floating signal lines. The HE3 suffix indicates AEC-Q101 qualification and RoHS compliance, whereas CA devices have symmetric breakdown in both directions and different marking (no cathode band).
What PCB layout guidance applies to the SMCJ58HE3/57T for optimal thermal and electrical performance?
Vishay specifies mounting on 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal to achieve rated PPPM and thermal performance. Minimizing trace inductance between the SMCJ58HE3/57T and protected node is critical-short, wide traces reduce voltage overshoot during fast transients, and thermal vias under pads improve heat dissipation in high-duty-cycle applications.
