Product details
Overview
SMCJ58CAHE3_A/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, designed for clamping voltage transients up to 1500 W peak pulse power with a 10/1000 μs waveform. It features a 58 V standoff voltage (VWM), 64.4–71.2 V breakdown voltage (VBR) at 1 mA test current, and clamps to ≤93.6 V at 16.0 A peak pulse current - deployed on power rails and signal lines of automotive ECUs and industrial sensor interfaces.
For engineers reviewing the SMCJ58CAHE3_A/H datasheet, SMCJ58CAHE3_A/H pinout, SMCJ58CAHE3_A/H application, or SMCJ58CAHE3_A/H equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance (RθJA = 75 °C/W), junction temperature range (−55 °C to +150 °C), and bidirectional clamping behavior critical for surge protection design in harsh environments.
Technical Context
The SMCJ58CAHE3_A/H operates as a bidirectional avalanche diode, symmetrically clamping transient overvoltages in both polarities without polarity marking. Its glass-passivated junction ensures stable breakdown characteristics and low incremental surge resistance, enabling fast response (<1 ns) to ESD and lightning-induced surges per IEC 61000-4-2/4-5.
Rated for 1500 W peak pulse power (10/1000 μs), it sustains 16.0 A IPPM while maintaining VC ≤ 93.6 V, with thermal derating above 25 °C per Fig. 2 and MSL Level 1 moisture sensitivity rating (peak reflow 260 °C). The device is AEC-Q101 qualified and RoHS-compliant under HE3 suffix designation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAC58CA | Same VWM (58 V), lower PPPM (500 W), smaller SMA package (DO-214AC), RθJA = 125 °C/W | Limited to lower-energy transients (IEC 61000-4-2 ±8 kV contact); unsuitable for load dump or high-current surges. | Select SAC58CA only for space-constrained consumer designs where 1500 W rating is unnecessary. |
| SMCJ58CAHM3_A/H | Identical electrical specs and AEC-Q101 qualification; halogen-free molding compound (per JESD201 Class 2 whisker test) | No functional difference; chosen when halogen-free compliance is mandated by OEM environmental policy (e.g., VW TL 813). | Choose SMCJ58CAHM3_A/H if halogen-free material declaration is contractually required; otherwise SMCJ58CAHE3_A/H suffices. |
Compared with SAC58CA, SMCJ58CAHE3_A/H delivers 3× higher surge power handling and superior thermal performance for automotive and industrial use; versus SMCJ58CAHM3_A/H, it offers identical protection capability with standard RoHS-compliant packaging - simplifying procurement where halogen-free is not enforced.

FAQ
What does the "CA" suffix mean in SMCJ58CAHE3_A/H?
The "CA" suffix denotes a bidirectional configuration - meaning the SMCJ58CAHE3_A/H conducts and clamps transient overvoltages identically in both polarities. Unlike unidirectional variants (e.g., SMCJ58A), it has no cathode marking and is used where signal lines or power rails may experience voltage reversals, such as AC-coupled interfaces or floating grounds. This eliminates the need for polarity-aware placement during assembly.
Is SMCJ58CAHE3_A/H suitable for automotive applications?
Yes, SMCJ58CAHE3_A/H is AEC-Q101 qualified and specifically designed for automotive use. Its construction - glass-passivated junction, MSL Level 1 rating, −55 °C to +150 °C operating range, and validated surge performance - meets requirements for engine control units, body control modules, and ADAS sensor interfaces. The HE3 suffix confirms RoHS compliance and automotive qualification per Vishay's ordering matrix.
How does SMCJ58CAHE3_A/H differ from SMCJ58AHE3_A/H?
SMCJ58CAHE3_A/H is bidirectional with symmetrical clamping behavior, while SMCJ58AHE3_A/H is unidirectional and features a cathode band marking. Electrically, SMCJ58AHE3_A/H supports forward conduction (VF = 3.5 V at 100 A) and has IFSM = 200 A, whereas SMCJ58CAHE3_A/H lacks forward conduction capability and is rated only for reverse surge suppression. Use SMCJ58CAHE3_A/H for AC or polarity-agnostic protection; choose SMCJ58AHE3_A/H only when forward current handling is required.
What is the maximum clamping voltage of SMCJ58CAHE3_A/H at rated surge current?
The maximum clamping voltage (VC) of SMCJ58CAHE3_A/H is 93.6 V at 16.0 A peak pulse current (IPPM), measured under the standardized 10/1000 μs waveform. This value represents the worst-case voltage imposed on the protected circuit during a full-rated surge event and must be compared against the absolute maximum voltage rating of downstream components to ensure survivability.
Does SMCJ58CAHE3_A/H require a heatsink for normal operation?
No external heatsink is required for SMCJ58CAHE3_A/H under typical transient conditions, as its 6.5 W steady-state power dissipation (PD) is managed via PCB copper pads (0.31″ × 0.31″ per terminal). However, sustained repetitive surges or elevated ambient temperatures (>70 °C) necessitate thermal derating per Figure 2 in the datasheet. Layout with ≥8 mm² copper per pad ensures RθJA remains near the specified 75 °C/W.
