Product details
Overview
SMCJ5.0C-E3/9AT from Vishay General Semiconductor is a bi-directional transient voltage suppressor (TVS) diode in DO-214AB (SMCJ) package, designed for robust overvoltage protection of sensitive electronics. It features a 5.0 V stand-off voltage (VWM), 1500 W peak pulse power (PPPM), clamping voltage of 9.2 V at 163 A, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the SMCJ5.0C-E3/9AT datasheet, SMCJ5.0C-E3/9AT pinout, SMCJ5.0C-E3/9AT application, or SMCJ5.0C-E3/9AT equivalent, this device is selected for high-energy surge suppression on low-voltage signal lines, DC power rails, and sensor interfaces where fast response (<1 ns), low clamping ratio, and bi-directional symmetry are critical.
Technical Context
The SMCJ5.0C-E3/9AT operates as a bi-directional avalanche diode with symmetrical breakdown characteristics in both polarities. Its 6.40–7.07 V minimum/maximum breakdown voltage (VBR) at 10 mA test current ensures consistent triggering across temperature and production lots.
It delivers 1500 W peak pulse power handling under standardized 10/1000 µs waveform conditions, with thermal resistance of 75 °C/W (junction-to-ambient) and 15 °C/W (junction-to-lead), enabling reliable operation up to +150 °C junction temperature without external heatsinking on recommended 8.0 mm × 8.0 mm copper pads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 5.0 V - Maximum reverse stand-off voltage before conduction begins; defines safe operating margin for 5 V systems. |
| VBR (min/max) | 6.40 V / 7.07 V - Breakdown occurs within this range at 10 mA; ensures predictable turn-on behavior. |
| VC @ IPPM | 9.2 V - Clamping voltage at 163 A peak pulse current; limits downstream voltage stress during transients. |
| PPPM | 1500 W - Peak pulse power dissipation capability under 10/1000 µs waveform; supports high-energy surge immunity. |
| ID @ VWM | 1000 µA - Maximum reverse leakage at 5.0 V; low enough to avoid loading 5 V logic or sensor bias networks. |
| TJ max. | +150 °C - Maximum junction temperature rating; enables use in under-hood automotive and industrial environments. |
| Package | DO-214AB (SMCJ) - Surface-mount, low-profile package with MSL Level 1 moisture sensitivity and matte tin-plated leads. |
Pinout & Package
DO-214AB (SMCJ) package: surface-mount, bi-directional device with no polarity marking; cathode band absent per specification for CA-suffix parts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient conduction path | Bi-directional terminals conduct equally in either polarity; no functional distinction between ends - mounted across protected line and ground. |
| Case (cathode band omitted) | Thermal and mechanical interface | Exposed metal slug provides primary thermal path to PCB copper; requires 8.0 mm × 8.0 mm pad per terminal for rated power derating. |
Key Features
| Feature | Design Value |
|---|---|
| Bi-directional clamping | Identical VBR and VC performance in both directions - eliminates polarity concerns in AC-coupled or floating signal lines. |
| AEC-Q101 qualification | Validated for automotive applications including engine control units, infotainment, and ADAS sensor interfaces. |
| Low incremental surge resistance | Enables tight clamping (9.2 V at 163 A) with minimal voltage overshoot during fast transients like ISO 7637-2 pulses. |
| MSL Level 1 rating | Unlimited floor life at ≤30 °C/60 % RH - compatible with standard SMT reflow without baking. |
| Glass passivated junction | Enhances long-term reliability and stability of breakdown voltage under thermal cycling and humidity stress. |
Applications
| Automotive Sensor Protection | Industrial I/O Interface |
|---|---|
Use Scenario: Protecting CAN bus transceivers and analog sensor inputs (e.g., pressure, temperature) from load dump and inductive switching transients in vehicle ECUs.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ5.0A-E3/61T | Lower PPPM (400 W), smaller SMA package (DO-214AC), higher RθJA (110 °C/W). | Suitable only for lower-energy transients; not rated for AEC-Q101 or 1500 W surges. | Select when board space is constrained and surge threat level is limited to IEC 61000-4-5 Level 2. |
| SMCJ5.0CAHE3/9AT | Same electrical specs and package, but AEC-Q101 qualified (HE3 suffix); identical VWM, VBR, VC, and PPPM. | Approved for automotive safety-critical subsystems requiring certified reliability documentation. | Choose for Tier 1 automotive designs requiring full AEC-Q101 traceability and qualification reports. |
Compared with SMCJ5.0C-E3/9AT, SMAJ5.0A-E3/61T offers footprint reduction at the cost of surge capacity and thermal performance, while SMCJ5.0CAHE3/9AT provides identical protection with formal automotive qualification - making it the preferred drop-in alternative where compliance evidence is mandatory.

FAQ
What is the polarity configuration of SMCJ5.0C-E3/9AT?
The SMCJ5.0C-E3/9AT is a bi-directional TVS diode with no polarity marking - the DO-214AB package lacks a cathode band, and its electrical characteristics apply identically in both directions. This makes SMCJ5.0C-E3/9AT ideal for protecting AC-coupled signals, differential buses, or floating DC lines where voltage reversals may occur during transients.
Does SMCJ5.0C-E3/9AT meet automotive qualification standards?
SMCJ5.0C-E3/9AT is RoHS-compliant and manufactured to commercial-grade specifications (E3 suffix). It is not AEC-Q101 qualified; for automotive applications requiring formal qualification, the SMCJ5.0CAHE3/9AT variant - which shares identical electrical parameters and package - must be used instead.
What is the maximum clamping voltage of SMCJ5.0C-E3/9AT under surge conditions?
The SMCJ5.0C-E3/9AT has a maximum clamping voltage (VC) of 9.2 V when subjected to its rated peak pulse current of 163 A under the standard 10/1000 µs waveform. This value is guaranteed per Vishay's datasheet and defines the upper voltage limit imposed on protected circuitry during worst-case surge events.
Can SMCJ5.0C-E3/9AT be used on a 3.3 V system?
No - SMCJ5.0C-E3/9AT has a 5.0 V stand-off voltage (VWM) and minimum breakdown of 6.40 V, making it unsuitable for direct placement on 3.3 V rails. Using it there would cause excessive leakage or premature conduction; for 3.3 V systems, select a part such as SMCJ3.3A or SMCJ3.3CA with matching VWM and VBR ratings.
What PCB layout guidance applies to SMCJ5.0C-E3/9AT for optimal thermal performance?
To achieve rated 1500 W pulse power, SMCJ5.0C-E3/9AT must be mounted on minimum 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal, as specified in Vishay's datasheet. Reducing pad size increases thermal resistance and causes derating of surge capability - the SMCJ5.0C-E3/9AT thermal performance depends directly on this copper area.
