Product details
Overview
SMCJ58AHE3_A/H from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for high-energy surge protection with 58 V standoff voltage (VWM), 64.4–71.2 V breakdown voltage (VBR), and 93.6 V clamping voltage (VC) at 16.0 A peak pulse current (IPPM). It delivers 1500 W peak pulse power (10/1000 µs waveform) and is AEC-Q101 qualified for automotive electronics protection.
For engineers reviewing the SMCJ58AHE3_A/H datasheet, SMCJ58AHE3_A/H pinout, SMCJ58AHE3_A/H application, or SMCJ58AHE3_A/H equivalent, key selection criteria include clamping performance under 10/1000 µs transients, thermal resistance (RθJA = 75 °C/W), AEC-Q101 qualification status, unidirectional polarity marking, and compatibility with automated SMT placement on 8.0 mm × 8.0 mm copper pads.
Technical Context
This TVS diode operates as a fast-acting shunt protector, leveraging an avalanche breakdown mechanism to clamp voltage spikes before they damage downstream ICs or MOSFETs. Its glass-passivated junction ensures stable VBR tolerance (±5%) and low incremental surge resistance, enabling consistent clamping across repetitive surges.
Designed for unidirectional operation, SMCJ58AHE3_A/H features a cathode band marking and exhibits 1.0 µA maximum reverse leakage at 58 V (VWM), with a temperature coefficient of VBR at +0.104 %/°C - critical for thermal stability in automotive under-hood environments up to +150 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 58 V - maximum continuous reverse operating voltage before clamping initiates |
| VBR min/max | 64.4 V / 71.2 V at 1.0 mA - guaranteed avalanche onset range defining turn-on threshold |
| VC @ IPPM | 93.6 V at 16.0 A - clamped voltage during 10/1000 µs surge, limiting stress on protected circuitry |
| PPPM | 1500 W - peak transient energy absorption capability per single 10/1000 µs pulse |
| RθJA | 75 °C/W - thermal resistance from junction to ambient, dictating derating above 25 °C ambient |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ58A-E3/57T | Lower PPPM (400 W), SMA package (smaller footprint, higher RθJA = 110 °C/W) | Suitable only for lower-energy transients; not AEC-Q101 qualified | Select when board space is constrained and surge energy ≤ 400 W suffices |
| SMCJ58CAHE3_A/H | Bidirectional variant; same VWM (58 V), symmetric clamping in both polarities | Required for AC-coupled or floating signal lines where polarity reversal occurs | Choose for RS-485, CAN FD, or Ethernet PHY protection where bidirectional clamping is mandatory |
Compared with SMAJ58A-E3/57T, SMCJ58AHE3_A/H provides 275 % higher surge capacity and automotive qualification; versus SMCJ58CAHE3_A/H, it offers lower capacitance and optimized unidirectional clamping for DC rails - critical for minimizing leakage and ensuring precise turn-on behavior.

FAQ
What is the clamping voltage of SMCJ58AHE3_A/H at its rated peak pulse current?
The SMCJ58AHE3_A/H has a maximum clamping voltage (VC) of 93.6 V at 16.0 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is measured with the device mounted on 8.0 mm × 8.0 mm copper pads per Vishay's recommended layout, ensuring repeatable thermal and electrical performance in production designs using SMCJ58AHE3_A/H.
Is SMCJ58AHE3_A/H qualified for automotive applications?
Yes, SMCJ58AHE3_A/H is AEC-Q101 qualified, as confirmed by Vishay's ordering code suffix "HE3" and documentation in datasheet 88394. This qualification covers temperature cycling, high-temperature reverse bias, and ESD testing - making SMCJ58AHE3_A/H suitable for under-hood and body-control module applications where reliability under thermal and electrical stress is mandatory.
How does the unidirectional configuration of SMCJ58AHE3_A/H affect its circuit placement?
The unidirectional configuration of SMCJ58AHE3_A/H requires correct orientation: the cathode band must connect to the protected line (e.g., 58 V rail), and the anode to ground. Reverse placement prevents clamping during positive transients and risks device failure. Unlike bidirectional variants, SMCJ58AHE3_A/H does not protect against negative-going surges on DC lines - a key design constraint when selecting SMCJ58AHE3_A/H.
What is the thermal resistance of SMCJ58AHE3_A/H, and how does it impact PCB layout?
SMCJ58AHE3_A/H has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted per Vishay's recommended 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pad layout. To maintain safe junction temperatures below +150 °C, designers must allocate sufficient copper area and avoid excessive ambient temperatures - especially critical in sealed enclosures where SMCJ58AHE3_A/H operates near its thermal limit.
Can SMCJ58AHE3_A/H be used in place of SMCJ58CAHE3_A/H?
No - SMCJ58AHE3_A/H is unidirectional and cannot replace the bidirectional SMCJ58CAHE3_A/H in AC-coupled or polarity-agnostic circuits. While both share identical VWM (58 V) and PPPM (1500 W), SMCJ58AHE3_A/H only clamps positive transients relative to ground. Substituting SMCJ58AHE3_A/H for SMCJ58CAHE3_A/H in RS-485 or CAN bus protection would leave negative transients unclamped, risking receiver damage.
