Product details
Overview
SMCJ60HE3/9AT 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 60 V standoff voltage (VWM), 66.7–73.7 V breakdown range (VBR at 1 mA), 96.8 V clamping voltage (VC) at 15.5 A peak pulse current, and 1500 W peak pulse power rating with 10/1000 µs waveform - deployed on power rails and signal lines in automotive ECUs and industrial motor drives.
For engineers reviewing the SMCJ60HE3/9AT datasheet, SMCJ60HE3/9AT pinout, SMCJ60HE3/9AT application, or SMCJ60HE3/9AT equivalent, key selection criteria include its AEC-Q101 qualification, 150 °C max junction temperature, RoHS-compliant matte tin-plated leads, and MSL Level 1 moisture sensitivity - critical for high-reliability automotive and industrial PCB assembly.
Technical Context
This unidirectional TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds VWM = 60 V, it avalanches to clamp transients at ≤96.8 V while diverting up to 15.5 A (10/1000 µs). Its glass-passivated junction ensures stable breakdown and low leakage (<1.0 µA at VWM), and thermal resistance RθJA = 75 °C/W enables operation up to 150 °C junction temperature.
The device is optimized for fast response (sub-nanosecond), low incremental surge resistance, and compatibility with automated SMT placement. Its DO-214AB package meets UL 94 V-0 flammability, supports 0.31" × 0.31" copper pad mounting per JEDEC standards, and is qualified to AEC-Q101 for automotive under-hood applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 60 V - maximum continuous reverse operating voltage before clamping begins; defines safe operating margin for 48 V nominal systems. |
| VBR (min/max) | 66.7 V / 73.7 V at 1 mA - guaranteed avalanche onset range; ensures consistent triggering across production lots. |
| VC @ IPPM | 96.8 V at 15.5 A - clamping voltage during 10/1000 µs surge; limits downstream IC stress below 100 V threshold. |
| PPPM | 1500 W - peak pulse power handling capacity; sustains high-energy transients like ISO 7637-2 Pulse 5a without failure. |
| IPPM | 15.5 A - peak pulse current capability; derived from 1500 W / 96.8 V; validates surge current path design. |
| TJ max | 150 °C - maximum junction temperature; supports under-hood automotive environments and high-ambient industrial enclosures. |
| Leakage ID | <1.0 µA at 60 V - ultra-low reverse leakage preserves battery life in always-on circuits and avoids false triggers. |
Pinout & Package
Package: DO-214AB (SMCJ), surface-mount, low-profile case with cathode band marking. Terminals are matte tin-plated leads, solderable per J-STD-002 and JESD 22-B102; polarity indicated by cathode band on unidirectional devices.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to system ground or lower-potential rail; completes shunt path during reverse overvoltage events. |
| Cathode | Reverse-biased clamping terminal | Connected to protected line (e.g., 48 V supply); avalanche conduction initiates here when VWM exceeded. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, humidity bias, and mechanical shock - suitable for ECU, ADAS, and body control modules. |
| Glass passivated junction | Ensures stable VBR tolerance and long-term parameter stability under thermal stress and humidity exposure. |
| MSL Level 1 (260 °C peak) | Enables standard lead-free reflow without preconditioning; eliminates moisture-related popcorning risk during SMT assembly. |
| UL 94 V-0 molding compound | Self-extinguishing encapsulation material prevents flame propagation in safety-critical enclosures per IEC 60695-11-10. |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients (e.g., inductive switch-off), improving clamping precision. |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ60AHE3/9AT | Lower PPPM = 600 W, smaller SMB (DO-214AA) package, same VWM/VC specs. | Suitable for space-constrained consumer or non-automotive industrial designs where 1500 W surge margin is not required. | Select when board area is limited and surge energy is ≤600 W; verify thermal derating on smaller pad layout. |
| SMCJ60A-E3/9AT | Same electrical specs but commercial-grade (non-AEC-Q101), no whisker test certification (E3 vs HE3). | Applicable in non-automotive contexts such as office equipment or white goods where automotive qualification is unnecessary. | Choose for cost-sensitive, non-automotive applications; avoid in automotive or mission-critical industrial deployments. |
Compared with SMCJ60HE3/9AT, SMBJ60AHE3/9AT trades surge capacity for footprint reduction, while SMCJ60A-E3/9AT retains identical protection performance but lacks AEC-Q101 validation and enhanced whisker resistance - making SMCJ60HE3/9AT the only choice for automotive-qualified 1500 W clamping in DO-214AB.

FAQ
What is the clamping voltage of SMCJ60HE3/9AT and how is it measured?
The clamping voltage (VC) of SMCJ60HE3/9AT is 96.8 V, measured at a peak pulse current (IPPM) of 15.5 A using a standardized 10/1000 µs double-exponential waveform. This value reflects the maximum voltage seen across the device during surge conduction and is critical for ensuring protected circuitry remains below its absolute maximum ratings. The SMCJ60HE3/9AT achieves this clamping performance consistently due to its tightly controlled avalanche characteristics and low incremental resistance.
Is SMCJ60HE3/9AT suitable for automotive applications?
Yes, SMCJ60HE3/9AT is explicitly AEC-Q101 qualified, with testing covering temperature cycling, high-temperature operating life, and mechanical shock - confirming suitability for under-hood and chassis-mounted automotive electronics. Its 150 °C maximum junction temperature, MSL Level 1 reflow compatibility, and JESD201 Class 2 whisker resistance make SMCJ60HE3/9AT appropriate for engine control modules, ADAS power supplies, and body electronics where reliability is non-negotiable.
How does the HE3 suffix differ from E3 in SMCJ60HE3/9AT?
The HE3 suffix denotes AEC-Q101 qualification and JESD201 Class 2 whisker resistance, whereas E3 indicates commercial-grade RoHS compliance only. SMCJ60HE3/9AT undergoes additional stress testing for automotive use, including biased HAST and temperature humidity bias, and features enhanced plating to prevent tin whisker growth under thermal cycling - requirements absent in SMCJ60A-E3/9AT. Both share identical electrical parameters and DO-214AB packaging.
What is the reverse leakage current specification for SMCJ60HE3/9AT at rated standoff voltage?
The maximum reverse leakage current (ID) for SMCJ60HE3/9AT is 1.0 µA at its rated standoff voltage (VWM) of 60 V and ambient temperature of 25 °C. This ultra-low leakage minimizes standby power loss in battery-backed systems and prevents false triggering in high-impedance sensing circuits. The value is guaranteed across the full operating temperature range and verified per ANSI/IEEE C62.35 test methods.
Can SMCJ60HE3/9AT be used in bi-directional protection configurations?
No - SMCJ60HE3/9AT is a unidirectional TVS diode, identifiable by its cathode band marking and specified breakdown behavior only in reverse bias. For bi-directional protection, Vishay offers the SMCJ60CA variant (e.g., SMCJ60CAHE3/9AT), which provides symmetrical clamping in both polarities. Using SMCJ60HE3/9AT in AC or floating signal paths without external polarity control risks forward conduction and potential failure.
