Product details
Overview
SMCJ58CAHE3_A/I from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for robust overvoltage protection of sensitive electronics. It features a 58 V standoff voltage (VWM), 93.6 V maximum clamping voltage (VC) at 16.0 A peak pulse current (IPPM), and 1500 W peak pulse power (PPPM) with 10/1000 µs waveform - deployed on power rails and signal lines in automotive ECUs and industrial sensor interfaces.
For engineers reviewing the SMCJ58CAHE3_A/I datasheet, SMCJ58CAHE3_A/I pinout, SMCJ58CAHE3_A/I application, or SMCJ58CAHE3_A/I equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance (RθJA = 75 °C/W), bidirectional clamping behavior, and direct replacement guidance for high-reliability surge protection design.
Technical Context
The SMCJ58CAHE3_A/I operates as a bidirectional avalanche diode, symmetrically clamping transients above ±64.4 V (min VBR) and below ±71.2 V (max VBR) at 1 mA test current. Its glass-passivated junction ensures stable breakdown and low leakage (<1 µA at VWM), while MSL Level 1 rating supports lead-free reflow up to 260 °C.
It delivers 1500 W surge handling per IEC 61000-4-5 (10/1000 µs) without degradation when mounted on 8.0 mm × 8.0 mm copper pads. The device exhibits a +0.104 %/°C temperature coefficient of VBR and is qualified to AEC-Q101 for automotive under-hood applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 58 V - Maximum continuous reverse operating voltage before clamping begins; sets safe margin below system rail. |
| VBR (min/max) | 64.4 V / 71.2 V at 1 mA - Confirmed bidirectional breakdown range; defines clamping onset threshold. |
| VC @ IPPM | 93.6 V at 16.0 A - Clamped voltage during 10/1000 µs surge; determines protected circuit's maximum stress level. |
| PPPM | 1500 W - Peak transient energy absorption capability; meets IEC 61000-4-5 Level 4 requirements. |
| RθJA | 75 °C/W - Junction-to-ambient thermal resistance; informs derating above 25 °C ambient. |
| TJ max. | +150 °C - Maximum junction temperature; enables operation in under-hood automotive environments. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD. |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, matte tin-plated leads, RoHS-compliant and halogen-free (HE3 suffix), MSL Level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (Anode) | Bidirectional terminal pair | No polarity marking; symmetrical terminals enable identical clamping in both directions. |
| Anode (Cathode) | Bidirectional terminal pair | Functionally identical to opposite terminal; no cathode band - distinguishes from unidirectional variants. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or floating signal lines without polarity concerns. |
| AEC-Q101 qualification | Validates reliability for automotive powertrain, body control, and ADAS modules requiring long-term field stability. |
| 1500 W peak pulse power | Withstands severe lightning-induced surges (IEC 61000-4-5) on 12 V/24 V vehicle buses and industrial I/O ports. |
| Low clamping ratio (VC/VBR ≈ 1.47) | Minimizes voltage overshoot during transients - critical for protecting 60 V-rated MOSFETs and CAN transceivers. |
| MSL Level 1, 260 °C peak | Supports standard lead-free reflow without preconditioning; eliminates moisture-related popcorning risk. |
Applications
| Automotive Power Distribution | Industrial Sensor Signal Lines |
|---|---|
Use Scenario: Protecting 12 V supply inputs in body control modules against load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Primary TVS clamp on main power rail, absorbing >100 J transients within microseconds. Use Value: Prevents latch-up or destruction of downstream PMICs and microcontrollers during alternator load dump events. |
Use Scenario: Shielding analog output lines (e.g., 4–20 mA current loops) from ESD and inductive switching noise. IC Role / Device Role / Timing Role: Bidirectional shunt protector placed directly at connector entry point. Use Value: Maintains signal integrity by limiting transient excursions to ≤93.6 V, well below op-amp input damage thresholds. |
| Telecom DC Power Feeds | Motor Drive Gate Driver Protection |
Use Scenario: Safeguarding PoE-powered equipment front-end circuits from induced surges on 48 V DC feeds. IC Role / Device Role / Timing Role: Secondary-level TVS on DC input after primary filter stage. Use Value: Clamps fast-rising transients (e.g., from nearby lightning strikes) before they reach isolated DC/DC converters. |
Use Scenario: Protecting high-side and low-side gate drivers in BLDC inverters from Miller-induced voltage spikes. IC Role / Device Role / Timing Role: Localized clamp across gate-source terminals of Si MOSFETs or GaN HEMTs. Use Value: Limits VGS excursion to <93.6 V, preventing gate oxide rupture during high-dI/dt switching transitions. |
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) and VC (93.6 V), but lower PPPM (600 W); smaller SMA package (DO-214AC). | Limited to lower-energy transients; unsuitable for ISO 7637-2 Pulse 5a/b or IEC 61000-4-5 Level 4. | Select only where board space is constrained and surge threat level is Class B or lower. |
| 1.5KE58CA | Same VWM/VC specs, but axial-leaded DO-201 package; higher RθJA (~50 °C/W on PCB, not heatsink). | Not suitable for automated SMT assembly; requires through-hole mounting and manual soldering. | Choose only for prototyping or legacy through-hole designs where rework tolerance outweighs production efficiency. |
Compared with SAC58CA and 1.5KE58CA, the SMCJ58CAHE3_A/I offers superior surge robustness (1500 W vs. 600 W or 1500 W with inferior thermal path), full SMT compatibility, and AEC-Q101 validation - making it the preferred choice for volume automotive and industrial production.

FAQ
What is the clamping voltage of the SMCJ58CAHE3_A/I under a 10/1000 µs surge?
The SMCJ58CAHE3_A/I clamps to a maximum of 93.6 V when subjected to its rated 16.0 A peak pulse current (IPPM) using the standard 10/1000 µs waveform. This value is measured at TA = 25 °C with recommended 8.0 mm × 8.0 mm copper pad layout. The SMCJ58CAHE3_A/I maintains this performance across its full operating temperature range, with minor derating above 25 °C per Figure 2 in the Vishay datasheet 88394.
Is the SMCJ58CAHE3_A/I suitable for automotive applications?
Yes, the SMCJ58CAHE3_A/I is AEC-Q101 qualified and explicitly designated for automotive use via its HE3 suffix. It meets requirements for temperature cycling, high-temperature reverse bias (HTRB), and ESD robustness. The SMCJ58CAHE3_A/I is deployed in engine control units, battery management systems, and ADAS camera modules where sustained operation from −40 °C to +125 °C ambient and immunity to load dump pulses are mandatory.
How does the bidirectional configuration of the SMCJ58CAHE3_A/I affect its usage compared to unidirectional variants?
The SMCJ58CAHE3_A/I has no polarity marking and provides identical clamping in both directions - essential for protecting AC-coupled data lines, transformer-isolated interfaces, or floating power domains. Unlike unidirectional SMCJ58A variants, the SMCJ58CAHE3_A/I eliminates risk of incorrect orientation during placement and avoids forward conduction issues on negative-going transients. Its symmetric VBR (64.4 V to 71.2 V) ensures consistent protection regardless of voltage polarity.
What is the thermal resistance of the SMCJ58CAHE3_A/I, and how does it impact layout?
The SMCJ58CAHE3_A/I 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, PCB layout must allocate sufficient copper area and avoid thermal bottlenecks. The SMCJ58CAHE3_A/I's RθJL of 15 °C/W further supports localized heat transfer to adjacent traces or planes.
Does the SMCJ58CAHE3_A/I meet RoHS and halogen-free requirements?
Yes, the SMCJ58CAHE3_A/I carries the HE3 suffix, indicating it is RoHS-compliant and halogen-free per Vishay's material categorization standard (document 99912). It uses matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, and passes JESD 201 Class 2 whisker testing. The molding compound meets UL 94 V-0 flammability rating, confirming suitability for safety-critical end equipment.
