Product details
Overview
SMCJ58A-E3/57T from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, designed for clamping voltage transients on power 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 (IPPM), and 1500 W peak pulse power (PPPM) with 10/1000 µs waveform - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial power supplies.
For engineers reviewing the SMCJ58A-E3/57T datasheet, SMCJ58A-E3/57T pinout, SMCJ58A-E3/57T application, or SMCJ58A-E3/57T equivalent, key selection criteria include unidirectional polarity, 1500 W surge capability, 93.6 V clamping under 16 A transient, RoHS-compliant matte tin terminations, and compatibility with automated SMT placement on 8.0 mm × 8.0 mm copper pads.
Technical Context
The SMCJ58A-E3/57T operates as a silicon avalanche diode with glass-passivated junction, delivering fast response time (<1 ns) and low incremental surge resistance to suppress ESD and inductive switching transients. Its unidirectional configuration uses cathode-band marking and exhibits 1.0 µA max reverse leakage at 58 V standoff.
Thermally, it supports operation from –55 °C to +150 °C junction temperature, with 75 °C/W junction-to-ambient thermal resistance (RθJA) on standard PCB pad layout and 15 °C/W junction-to-lead (RθJL). It meets MSL Level 1 per J-STD-020 and is rated for 200 A non-repetitive forward surge (IFSM, 8.3 ms half-sine).
Key Specifications

Pinout & Package
SMCJ58A-E3/57T uses the SMC (DO-214AB) package: a 2-terminal surface-mount device with cathode identified by a band on the body. Leads are matte tin-plated, solderable per J-STD-002 and JESD 22-B102, and meet JESD 201 Class 2 whisker resistance.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAC58A-TB-E3/57T | Same VWM (58 V), lower PPPM (600 W), smaller SMA package (DO-214AC) | Lower surge margin; suitable only for sub-1 kV IEC 61000-4-5 applications | Select when board space is constrained and surge threat level is limited to IEC 61000-4-4 EFT only |
| 1.5SMC58A | Identical electrical specs (VWM, VBR, VC, PPPM), same SMC package, but non-AEC-Q101 commercial grade | No automotive qualification; not approved for under-hood deployment per AEC-Q101 | Choose for cost-sensitive industrial designs where AEC-Q101 is not mandated |

FAQ
What is the clamping voltage of SMCJ58A-E3/57T at its rated peak pulse current?
The SMCJ58A-E3/57T has a maximum clamping voltage (VC) of 93.6 V when subjected to its rated 16 A peak pulse current (IPPM) using the standard 10/1000 µs waveform. This value is measured under specified test conditions (TA = 25 °C, mounted on 8.0 mm × 8.0 mm copper pads) and defines the upper voltage limit imposed on protected circuitry during transient events. The SMCJ58A-E3/57T maintains this clamping performance across its operational temperature range.
Is SMCJ58A-E3/57T qualified for automotive applications?
The base SMCJ58A-E3/57T is RoHS-compliant and commercial-grade; it is not AEC-Q101 qualified. However, Vishay offers the automotive variant SMCJ58AHE3_A/H (with HE3 suffix), which carries full AEC-Q101 qualification for under-hood use. Engineers specifying SMCJ58A-E3/57T for automotive designs must verify qualification status via ordering code - the SMCJ58A-E3/57T itself does not carry automotive qualification.
What is the thermal resistance of SMCJ58A-E3/57T, and how does it affect PCB layout?
The SMCJ58A-E3/57T has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on the minimum recommended 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal. This value assumes no additional heatsinking. To maintain TJ ≤ 150 °C under 6.5 W steady-state dissipation, designers must ensure adequate copper area and airflow - undersized pads will raise operating temperature and reduce surge endurance. The SMCJ58A-E3/57T's RθJL of 15 °C/W supports efficient heat transfer to PCB traces.
Can SMCJ58A-E3/57T be used in bidirectional configurations?
No - the SMCJ58A-E3/57T is strictly unidirectional, indicated by its "A" suffix and cathode band marking. Bidirectional variants carry the "CA" suffix (e.g., SMCJ58CA). Using SMCJ58A-E3/57T in reverse-biased configurations risks premature conduction or failure, as it lacks symmetrical breakdown characteristics. For AC line or differential signal protection, select the designated bidirectional part SMCJ58CA instead of SMCJ58A-E3/57T.
What is the maximum reverse leakage current of SMCJ58A-E3/57T at its standoff voltage?
The SMCJ58A-E3/57T exhibits a maximum reverse leakage current (ID) of 1.0 µA at its rated standoff voltage (VWM) of 58 V and TA = 25 °C. This ultra-low leakage ensures minimal power loss in high-impedance monitoring circuits and preserves battery life in always-on automotive modules. Leakage increases with temperature but remains below 10 µA up to +125 °C, as confirmed in Vishay's thermal derating curves.
