Product details
Overview
SMCJ9.0HE3/57T from Vishay General Semiconductor is a surface-mount, AEC-Q101-qualified, bi-directional transient voltage suppressor (TVS) in DO-214AB (SMCJ) package. It features 9.0 V stand-off voltage (VWM), 15.4 V clamping voltage (VC) at 97.4 A peak pulse current (IPPM), and 1500 W peak pulse power (PPPM) with 10/1000 µs waveform. It protects automotive sensor signal lines and power rails against ESD, load dump, and inductive switching transients.
For engineers reviewing the SMCJ9.0HE3/57T datasheet, SMCJ9.0HE3/57T pinout, SMCJ9.0HE3/57T application, or SMCJ9.0HE3/57T equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, DO-214AB mechanical data, clamping performance under standardized surge conditions, and direct alternatives for automotive-grade circuit protection design.
Technical Context
The SMCJ9.0HE3/57T operates as a bi-directional avalanche diode, symmetrically clamping voltage transients above ±10.0 V (min VBR) and below ±9.0 V (VWM) in both polarities. Its glass-passivated junction ensures stable breakdown behavior and low leakage (<1.0 µA at VWM), while its low incremental surge resistance enables consistent clamping across repetitive surges.
Designed for high-energy transient suppression, it sustains 1500 W peak pulse power per 10/1000 µs waveform when mounted on 8.0 mm × 8.0 mm copper pads, with thermal resistance RθJA = 75 °C/W and maximum junction temperature of +150 °C. The HE3 suffix confirms AEC-Q101 qualification and JESD 201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 9.0 V - Maximum reverse stand-off voltage before conduction; defines safe operating window for protected circuitry. |
| VBR (min) | 10.0 V - Minimum breakdown voltage at 1 mA test current; guarantees reliable turn-on during overvoltage events. |
| VC @ IPPM | 15.4 V - Clamped voltage at 97.4 A peak pulse current; determines maximum stress imposed on downstream ICs. |
| PPPM | 1500 W - Peak pulse power handling capability with 10/1000 µs waveform; supports high-energy automotive transients. |
| ID @ VWM | <1.0 µA - Reverse leakage current at rated stand-off voltage; ensures minimal standby power loss and signal integrity. |
| TJ max. | +150 °C - Maximum junction temperature rating; enables operation in under-hood automotive environments. |
| Package | DO-214AB (SMCJ) - Standardized surface-mount outline with 8.0 mm × 8.0 mm thermal pad footprint per terminal. |
Pinout & Package
SMCJ9.0HE3/57T uses the DO-214AB (SMCJ) package: molded plastic case with J-bend leads, UL 94 V-0 rated compound, matte tin-plated terminals solderable per J-STD-002 and JESD 22-B102. Bi-directional construction means no polarity marking; both terminals are electrically symmetrical.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient conduction path | Bi-directional avalanche junction - conducts equally in either polarity once VBR is exceeded. |
| Case / Body | Thermal and mechanical interface | Non-conductive molding compound; requires 8.0 mm × 8.0 mm copper pad per lead for rated PPPM derating. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive applications including engine control units, ADAS sensors, and body electronics. |
| Glass passivated junction | Ensures stable VBR tolerance (±10%), low leakage, and long-term reliability under thermal cycling. |
| Low incremental surge resistance | Enables tight VC control (15.4 V @ 97.4 A), minimizing voltage overshoot during fast transients. |
| MSL Level 1 (260 °C peak) | Compatible with standard lead-free reflow profiles without moisture sensitivity concerns. |
| JESD 201 Class 2 whisker resistance | Prevents tin whisker growth under high humidity and temperature stress, critical for automotive longevity. |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ9.0AHE3/A | Lower PPPM (400 W), smaller SMA package (DO-214AC), uni-directional only, same VWM/VBR range. | Not suitable for bi-directional line protection; limited to single-polarity DC rails with lower surge exposure. | Select only if space-constrained and surge energy is ≤400 W; verify polarity alignment during layout. |
| SMCJ9.0CAHE3/57T | Identical electrical specs and package; CA suffix explicitly denotes bi-directional version (SMCJ9.0HE3/57T is functionally equivalent but marked per legacy convention). | No functional difference; both meet same AEC-Q101, MSL Level 1, and JESD 201 Class 2 requirements. | SMCJ9.0CAHE3/57T is a direct marking variant - use interchangeably where bi-directionality is required. |
Compared with SMAJ9.0AHE3/A, SMCJ9.0HE3/57T delivers 3.75× higher surge power handling and bi-directional symmetry essential for AC-coupled or differential signal lines; versus SMCJ9.0CAHE3/57T, it is functionally identical with equivalent automotive qualification and thermal performance.

FAQ
What is the clamping voltage of SMCJ9.0HE3/57T at its rated peak pulse current?
The SMCJ9.0HE3/57T has a maximum clamping voltage (VC) of 15.4 V when subjected to its rated peak pulse current (IPPM) of 97.4 A using the standard 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and confirmed in Vishay's datasheet revision 11-Dec-12, ensuring predictable overvoltage limiting for downstream ICs.
Is SMCJ9.0HE3/57T suitable for automotive applications?
Yes, SMCJ9.0HE3/57T is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood environments. Its DO-214AB package meets MSL Level 1, its terminals pass JESD 201 Class 2 whisker testing, and its 150 °C TJ max. supports operation in engine control, ADAS, and body electronics systems.
Does SMCJ9.0HE3/57T have polarity markings?
No, SMCJ9.0HE3/57T is a bi-directional TVS device and carries no polarity marking on its DO-214AB package. Both terminals are functionally identical, allowing placement without orientation constraints - a key advantage for protecting AC-coupled or differential signal paths.
What is the reverse leakage current specification for SMCJ9.0HE3/57T at 9.0 V?
At the rated stand-off voltage (VWM) of 9.0 V and TA = 25 °C, the SMCJ9.0HE3/57T exhibits a maximum reverse leakage current (ID) of 1.0 µA. This low leakage preserves signal integrity and minimizes standby power loss in battery-sensitive or high-impedance sensing circuits.
How does the HE3 suffix differ from E3 in SMCJ9.0HE3/57T?
The HE3 suffix in SMCJ9.0HE3/57T indicates RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance, whereas E3 denotes commercial-grade RoHS compliance only. For automotive or high-reliability designs, SMCJ9.0HE3/57T is the validated choice - not interchangeable with E3 variants in qualified applications.
