Product details
Overview
SMCJ60CAHE3_A/H 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 60 V standoff voltage (VWM), 96.8 V maximum clamping voltage (VC) at 15.5 A peak pulse current (IPPM), and 1500 W peak pulse power dissipation (10/1000 µs waveform), suitable for automotive-grade ESD and surge protection on power rails and signal lines.
For engineers reviewing the SMCJ60CAHE3_A/H datasheet, SMCJ60CAHE3_A/H pinout, SMCJ60CAHE3_A/H application, or SMCJ60CAHE3_A/H equivalent, key selection criteria include bidirectional clamping symmetry, AEC-Q101 qualification, low incremental surge resistance, and compatibility with automated SMT assembly on 8 mm × 8 mm copper pads.
Technical Context
This device operates as a voltage-clamped crowbar during transients, leveraging an avalanche breakdown mechanism to divert surge energy away from downstream circuitry. Its bidirectional structure ensures symmetrical clamping in both polarities, eliminating polarity sensitivity in AC-coupled or floating interfaces.
Designed for high-reliability environments, SMCJ60CAHE3_A/H meets MSL Level 1 per J-STD-020, supports peak junction temperatures up to +150 °C, and exhibits a temperature coefficient of VBR of +0.105 %/°C - enabling stable clamping performance across automotive thermal ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 60 V - Maximum continuous reverse operating voltage before clamping initiates |
| VBR min/max | 66.7 V / 73.7 V at 1 mA - Confirmed breakdown threshold range under standardized test conditions |
| VC @ IPPM | 96.8 V at 15.5 A - Clamped voltage during 10/1000 µs surge, defining worst-case stress on protected ICs |
| PPPM | 1500 W - Peak transient power handling capability, critical for IEC 61000-4-5 Level 4 compliance |
| TJ max | +150 °C - Enables operation in under-hood automotive environments without derating |
| Package | SMC (DO-214AB) - Surface-mount outline with 7.75 mm × 6.22 mm footprint and 2.62 mm height for high-power density layout |
| AEC-Q101 | Qualified - Validated for automotive electronic systems per stress-test requirements including HTOL, TC, and HAST |
Pinout & Package
SMCJ60CAHE3_A/H uses the standard SMC (DO-214AB) package: two-terminal, bidirectional device with no polarity marking. The case is molded epoxy meeting UL 94 V-0; terminals are matte tin-plated for J-STD-002 solderability. Mounting requires 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per lead for rated power dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry (negative polarity) | One terminal of symmetrical avalanche junction; accepts surge current in either direction |
| Cathode | Transient current entry (positive polarity) | Second terminal of symmetrical avalanche junction; identical electrical role to Anode in bidirectional mode |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC lines, differential buses, or ungrounded sensors 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 rating | Supports immunity to 1 kV/500 A IEC 61000-4-5 combination wave surges with margin |
| Low clamping ratio (VC/VBR ≈ 1.45) | Minimizes let-through voltage to protect 65 V-rated MOSFETs and 75 V-rated CAN transceivers |
| MSL Level 1 rating | Permits reflow soldering at 260 °C peak without moisture-induced failure risk |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|

IC Role / Device Role / Timing Role: Primary clamping element placed at power entry point before DC-DC converters and microcontrollers. Use Value: Limits rail voltage to ≤96.8 V during 15.5 A surges, preventing latch-up or gate oxide damage in downstream 60 V-rated FETs. | Use Scenario: Safeguarding analog sensor outputs (e.g., pressure, temperature) connected to PLC inputs against ESD and inductive switching noise. IC Role / Device Role / Timing Role: Low-capacitance shunt protector on signal line, placed adjacent to connector. Use Value: Clamps ±15 kV contact ESD (IEC 61000-4-2) within <1 ns while adding <5 pF parasitic capacitance to preserve signal integrity. |

IC Role / Device Role / Timing Role: Secondary protector after primary polymer PTC, placed near USB connector. Use Value: Clamps ±8 kV air discharge (IEC 61000-4-2) to <15 V across D+/D−, preventing PHY latch-up and enumeration failure. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAC60CA | Lower PPPM (600 W), same VWM/VC, smaller SMA package | Not rated for AEC-Q101; limited to commercial-grade consumer/industrial use | Select when space-constrained layouts preclude SMC and automotive qualification is unnecessary |
| 1.5KE60CA | Higher VC (100 V), axial-leaded DO-201 package, no AEC-Q101 | Requires through-hole mounting; unsuitable for high-volume SMT production | Choose only for legacy board rework or prototyping where SMT compatibility is not required |
Compared with SAC60CA and 1.5KE60CA, SMCJ60CAHE3_A/H delivers higher surge robustness (1500 W vs. 600 W/1500 W), automotive qualification, and SMT process compatibility - making it the preferred choice for new automotive and industrial designs requiring production scalability and long-term reliability.

FAQ
What is the clamping voltage of SMCJ60CAHE3_A/H at its rated peak pulse current?
The SMCJ60CAHE3_A/H has a maximum clamping voltage (VC) of 96.8 V at 15.5 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value defines the upper voltage limit imposed on protected circuitry during surge events and is measured with the device mounted on 8.0 mm × 8.0 mm copper pads per terminal as specified in the Vishay datasheet 88394.
Is SMCJ60CAHE3_A/H qualified for automotive applications?
Yes, SMCJ60CAHE3_A/H is AEC-Q101 qualified, as confirmed by Vishay's ordering code suffix "HE3" and documentation in datasheet 88394. This qualification covers stress tests including high-temperature operating life, temperature cycling, and humidity bias, validating its suitability for automotive powertrain, body electronics, and ADAS modules.
How does the bidirectional configuration of SMCJ60CAHE3_A/H affect its use in circuit design?
The bidirectional configuration of SMCJ60CAHE3_A/H eliminates polarity dependency, allowing placement on AC-coupled lines, differential pairs (e.g., RS-485, CAN), or ungrounded sensor outputs without orientation constraints. Unlike unidirectional TVS diodes, SMCJ60CAHE3_A/H provides symmetrical clamping in both directions, simplifying layout and reducing BOM count in floating or dual-polarity systems.
What is the thermal resistance of SMCJ60CAHE3_A/H, and how does it impact PCB layout?
SMCJ60CAHE3_A/H has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on minimum recommended pad layout. To achieve full 1500 W pulse rating, Vishay specifies 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal. Reducing pad area increases thermal impedance and requires derating of surge capability per Figure 2 in datasheet 88394.
Does SMCJ60CAHE3_A/H have a defined polarity marking on the package?
No, SMCJ60CAHE3_A/H has no polarity marking on the SMC (DO-214AB) package because it is a bidirectional device. Unlike unidirectional variants (e.g., SMCJ60A), which feature a cathode band, the CA-suffixed version uses a symmetrical junction structure - meaning both terminals function identically regardless of voltage polarity, and orientation during placement is irrelevant.
