Product details
Overview
SMCJ60CHE3/9AT from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-214AB (SMCJ) package, rated for 60 V standoff voltage (VWM), 66.7–73.7 V breakdown (VBR), 1500 W peak pulse power (PPPM), and 15.5 A peak pulse current (IPPM) at 10/1000 μs waveform. It protects MOSFETs, ICs, and sensor signal lines in automotive power systems against inductive switching transients.
For engineers reviewing the SMCJ60CHE3/9AT datasheet, SMCJ60CHE3/9AT pinout, SMCJ60CHE3/9AT application, or SMCJ60CHE3/9AT equivalent, key selection criteria include clamping voltage (96.8 V at IPPM), AEC-Q101 qualification, RoHS-compliant matte tin plating, and MSL Level 1 moisture sensitivity rating for reflow compatibility.
Technical Context
This TVS diode operates as a unidirectional clamping device with a glass-passivated silicon junction, delivering sub-nanosecond response to ESD and surge events. Its low incremental surge resistance and fast response time ensure effective suppression of transients induced by load switching in 12 V/24 V automotive subsystems.
The device is thermally rated for TJ = –55 °C to +150 °C, with RθJA = 75 °C/W and RθJL = 15 °C/W, and is designed for mounting on 8.0 mm × 8.0 mm copper pads per terminal to sustain 1500 W pulses without thermal runaway.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| VC @ IPPM | 96.8 V - clamping voltage at 15.5 A peak pulse current, limiting downstream voltage stress |
| PPPM | 1500 W - peak surge power handling capability under standardized 10/1000 μs waveform |
| ID @ VWM | 1.0 μA - reverse leakage at 60 V, ensuring minimal standby power loss and signal integrity |
| TJ max | +150 °C - maximum junction temperature, supporting under-hood automotive deployment |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD |
Pinout & Package
Package: DO-214AB (SMCJ), surface-mount, low-profile, bi-planar J-bend leads. Polarity indicated by cathode band; anode and cathode terminals are non-reversible for unidirectional operation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ60AHE3/9AT | Lower PPPM (400 W), smaller DO-214AC (SMA) package, same VWM/VBR range | Not suitable for 1500 W load dump; limited to low-energy ESD/signal-line protection | Select only where space-constrained layouts and lower surge levels permit reduced power rating |
| SMCJ60A-E3/9AT | Same electrical specs but commercial-grade (non-AEC-Q101), no automotive qualification testing | Lacks automotive reliability validation; unsuitable for safety-critical or under-hood use | Acceptable for industrial or consumer applications where AEC-Q101 is not mandated |
Compared with SMCJ60A-E3/9AT and SMAJ60AHE3/9AT, the SMCJ60CHE3/9AT uniquely combines 1500 W surge capacity, AEC-Q101 qualification, and DO-214AB thermal performance-making it the only option qualified for automotive power rail protection requiring both high energy handling and automotive reliability assurance.

FAQ
What is the clamping voltage of the SMCJ60CHE3/9AT and why does it matter?
The SMCJ60CHE3/9AT has a maximum clamping voltage (VC) of 96.8 V at its rated peak pulse current (15.5 A, 10/1000 μs). This value defines the highest voltage that will appear across protected circuitry during a surge event. Keeping VC well below the absolute maximum ratings of downstream components-such as 100 V-rated MOSFETs or 80 V-input DC/DC converters-is essential to prevent damage. The SMCJ60CHE3/9AT achieves a clamping ratio (VC/VBR) of ~1.36, indicating efficient voltage limiting relative to its breakdown threshold.
Is the SMCJ60CHE3/9AT suitable for automotive applications?
Yes, the SMCJ60CHE3/9AT is AEC-Q101 qualified and explicitly designed for automotive use. Its qualification covers temperature cycling, highly accelerated life testing (HALT), and ESD robustness required for under-hood and body electronics. The HE3 suffix denotes AEC-Q101 compliance, and the device meets ISO 7637-2 Pulse 1, 2a, and 5a immunity requirements when properly mounted on recommended 8.0 mm × 8.0 mm copper pads. This makes the SMCJ60CHE3/9AT appropriate for ECU power rails, lighting modules, and sensor interfaces in passenger vehicles and commercial trucks.
How does the SMCJ60CHE3/9AT differ from the SMCJ60A-E3/9AT?
The SMCJ60CHE3/9AT and SMCJ60A-E3/9AT share identical electrical specifications-including VWM (60 V), VBR (66.7–73.7 V), PPPM (1500 W), and package (DO-214AB)-but differ in qualification level. The "HE3" suffix indicates AEC-Q101 qualification, including extended reliability testing for automotive use, whereas the "E3" suffix denotes commercial-grade compliance only. Both are RoHS-compliant and use matte tin plating, but only the SMCJ60CHE3/9AT is approved for safety-critical or under-hood automotive deployments per OEM requirements.
What is the thermal resistance and how does it affect PCB layout for the SMCJ60CHE3/9AT?
The SMCJ60CHE3/9AT has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W and junction-to-lead (RθJL) of 15 °C/W. These values assume mounting on minimum recommended 0.31″ × 0.31″ (8.0 mm × 8.0 mm) copper pads per terminal. To sustain repeated 1500 W surges without exceeding TJ(max) = +150 °C, designers must provide adequate copper area and avoid thermal bottlenecks. Reducing pad size or using thin FR-4 increases RθJA, risking thermal runaway during high-duty-cycle transients-so the SMCJ60CHE3/9AT must be laid out per Vishay's specified footprint.
Does the SMCJ60CHE3/9AT have polarity marking and how is it oriented in circuit?
Yes, the SMCJ60CHE3/9AT is unidirectional and features a visible cathode band on the DO-214AB package. In circuit, the banded end (cathode) connects to the line being protected (e.g., 12 V rail), while the anode connects to ground or the lowest-potential reference node. This orientation ensures the device remains reverse-biased during normal operation (<60 V), conducting only when transient voltage exceeds VBR. Reversing polarity would render the device ineffective as a clamp, since forward conduction (VF ≈ 3.5 V at 100 A) offers no meaningful overvoltage protection.
