Product details
Overview
SMCJ6.0CHE3/9AT from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-214AB (SMCJ) package, designed for robust overvoltage protection of sensitive electronics. It features a 6.0 V stand-off voltage (VWM), 6.67–7.37 V breakdown voltage (VBR) at 10 mA, 1500 W peak pulse power (10/1000 µs), 145.6 A peak pulse current (IPPM), and clamps to ≤10.3 V at rated surge. It is AEC-Q101 qualified and used in automotive power line and sensor interface protection.
For engineers reviewing the SMCJ6.0CHE3/9AT datasheet, SMCJ6.0CHE3/9AT pinout, SMCJ6.0CHE3/9AT application, or SMCJ6.0CHE3/9AT equivalent, key selection criteria include unidirectional polarity, 1500 W surge rating, 10.3 V clamping voltage at IPPM, AEC-Q101 qualification, RoHS compliance with HE3 whisker class 2, and DO-214AB thermal performance (RθJA = 75 °C/W).
Technical Context
The SMCJ6.0CHE3/9AT operates as a silicon avalanche diode that enters controlled breakdown above its reverse stand-off voltage (6.0 V), limiting transient energy by clamping voltage across protected circuit nodes. Its glass-passivated junction ensures stable VBR tolerance and low leakage (<1000 µA at VWM).
It delivers fast response time (<1.0 ps), low incremental surge resistance, and meets MSL level 1 per J-STD-020 (260 °C peak reflow). Thermal design relies on 0.31" × 0.31" copper pads per terminal, supporting 6.5 W power dissipation at TA = 50 °C and 150 °C maximum junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - Maximum continuous reverse operating voltage before clamping begins |
| VBR min/max | 6.67 V / 7.37 V at IT = 10 mA - Confirmed breakdown range ensuring reliable turn-on margin |

Applications
| Automotive Power Line Protection | Industrial Sensor Interface |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs against load dump (ISO 7637-2 Pulse 5a) and alternator transients. IC Role / Device Role / Timing Role: Unidirectional TVS placed between battery rail and input filter capacitor, clamping surges before they reach DC/DC converters and microcontrollers. Use Value: 1500 W PPPM and ≤10.3 V clamping ensure downstream ICs remain within absolute maximum ratings during 120 V/50 ms transients. | Use Scenario: Shielding analog sensor outputs (e.g., pressure, temperature) from ESD and cable discharge events in factory automation systems. IC Role / Device Role / Timing Role: TVS mounted at connector entry point, shunting fast transients (<1 ns rise) before reaching op-amp front-end or ADC inputs. Use Value: Sub-nanosecond response and <1000 µA leakage preserve signal fidelity while enabling IEC 61000-4-2 ±8 kV contact discharge compliance. |
| Telecom DC Power Input | Consumer USB Power Delivery |
Use Scenario: Safeguarding 48 V PoE-powered equipment (e.g., IP cameras, access points) from induced lightning surges on Ethernet cables. IC Role / Device Role / Timing Role: Primary surge clamp on PSE-side DC input, coordinated with upstream GDT or MOV for staged protection. Use Value: 145.6 A IPPM and DO-214AB thermal mass sustain multiple 10/1000 µs surges without degradation, meeting IEC 61000-4-5 Level 3. | Use Scenario: Adding secondary overvoltage protection on USB-C VBUS lines after primary buck converter, guarding against adapter fault conditions. IC Role / Device Role / Timing Role: Fast-acting unidirectional clamp referenced to system ground, activated only when VBUS exceeds 6.0 V. Use Value: Tight 6.67–7.37 V VBR window prevents nuisance triggering during normal 5–20 V PD negotiation while blocking >10 V faults. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.0AHE3/A | Lower PPPM (400 W), smaller DO-214AC (SMA) package, same VWM/VBR specs | Not suitable for 1500 W load dump; limited to lower-energy ESD/cable discharge | Select when board space is constrained and surge energy is ≤400 W |
| SMCJ6.0AHE3/9AT | Same electrical specs and DO-214AB package, but unqualified for AEC-Q101 | Lacks automotive reliability validation; requires additional qualification testing for vehicle use | Select for cost-sensitive industrial designs where AEC-Q101 is not mandated |
Compared with SMCJ6.0AHE3/9AT and SMAJ6.0AHE3/A, the SMCJ6.0CHE3/9AT uniquely combines 1500 W surge capability, AEC-Q101 qualification, and HE3-class whisker resistance-making it the only option qualified for under-hood automotive deployment without derating or supplemental testing.

FAQ
What is the clamping voltage of the SMCJ6.0CHE3/9AT at its rated peak pulse current?
The SMCJ6.0CHE3/9AT clamps to a maximum of 10.3 V at its rated peak pulse current (IPPM) of 145.6 A under the standardized 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during full-rated surge events. The SMCJ6.0CHE3/9AT maintains this clamping performance across its operational junction temperature range (−55 °C to +150 °C), with minor derating above TA = 25 °C per Figure 2 in the Vishay datasheet 88394.
Is the SMCJ6.0CHE3/9AT suitable for automotive applications?
Yes, the SMCJ6.0CHE3/9AT is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood environments. Its construction includes glass-passivated junction, MSL Level 1 reflow compatibility, and HE3-class whisker resistance per JESD 201 Class 2. The SMCJ6.0CHE3/9AT meets ISO 7637-2 Pulse 5a load dump requirements when applied with appropriate PCB layout (0.31" × 0.31" copper pads) and has been validated for temperature cycling, HTRB, and mechanical shock per AEC-Q101 test plan.
How does the HE3 suffix differ from the E3 suffix in SMCJ6.0CHE3/9AT?
The HE3 suffix denotes AEC-Q101 qualification and JESD 201 Class 2 whisker resistance, whereas E3 indicates RoHS compliance and JESD 201 Class 1A whisker resistance only. The SMCJ6.0CHE3/9AT's HE3 marking confirms full automotive reliability validation-including extended temperature life testing and bias-HAST-making it distinct from commercial-grade E3 variants like SMCJ6.0AE3/9AT. Both share identical electrical specs and DO-214AB packaging.
What is the maximum reverse leakage current of the SMCJ6.0CHE3/9AT at its stand-off voltage?
The SMCJ6.0CHE3/9AT exhibits a maximum reverse leakage current (ID) of 1000 µA at its 6.0 V stand-off voltage (VWM), measured at TA = 25 °C. This low leakage ensures minimal impact on power rail stability and signal integrity in always-on systems. Leakage remains within specification up to TJ = 125 °C; above that, it increases predictably per the device's thermal characteristics and must be accounted for in high-temperature designs using the SMCJ6.0CHE3/9AT.
Can the SMCJ6.0CHE3/9AT be used in bi-directional configurations?
No, the SMCJ6.0CHE3/9AT is a unidirectional TVS diode, as confirmed by its "A" suffix and cathode band marking. Bi-directional variants carry the "CA" suffix (e.g., SMCJ6.0CA) and lack polarity marking. Using the SMCJ6.0CHE3/9AT in bi-directional applications would result in forward conduction during negative transients, potentially damaging the device or failing to protect the circuit. For symmetric surge protection, select SMCJ6.0CHE3/9AT's bi-directional counterpart SMCJ6.0CAHE3/9AT instead.
