Product details
Overview
SMCJ6.0C-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 on signal and power lines. 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), 10.3 V clamping voltage at 145.6 A IPPM, and AEC-Q101 qualification for automotive use.
For engineers reviewing the SMCJ6.0C-E3/9AT datasheet, SMCJ6.0C-E3/9AT pinout, SMCJ6.0C-E3/9AT application, or SMCJ6.0C-E3/9AT equivalent, key selection criteria include bi-directional clamping capability, low clamping ratio (VC/VWM ≈ 1.72), MSL Level 1 moisture sensitivity, RoHS-compliant matte tin terminations, and suitability for inductive load switching transients in automotive ECUs and sensor interfaces.
Technical Context
The SMCJ6.0C-E3/9AT operates as a bi-directional avalanche diode with symmetrical clamping in both polarities, enabling protection of AC-coupled or floating signal paths without polarity constraints. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1000 µA at VWM), while the low incremental surge resistance supports effective energy diversion during fast transients.
Designed for surface-mount assembly on 8.0 mm × 8.0 mm copper pads per terminal, it delivers thermal performance with RθJA = 75 °C/W and RθJL = 15 °C/W, supporting operation from –55 °C to +150 °C junction temperature. The device meets UL 497B recognition and complies with ANSI/IEEE C62.35 surge standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - Maximum continuous reverse operating voltage before clamping begins; defines safe working range for protected circuitry. |
| VBR min/max | 6.67 V / 7.37 V at 10 mA - Confirmed breakdown threshold ensuring reliable turn-on during overvoltage events. |
| VC @ IPPM | 10.3 V at 145.6 A - Clamped voltage under 1500 W 10/1000 µs surge; limits stress on downstream components. |
| PPPM | 1500 W - Peak pulse power handling capacity; enables protection against high-energy transients like ISO 7637-2 Pulse 1/2a/5a. |
| ID @ VWM | ≤1000 µA - Low reverse leakage preserves signal integrity and minimizes standby power loss in sensitive analog circuits. |
| TJ max | +150 °C - Extended junction temperature rating supports under-hood automotive deployment and industrial environments. |
| MSL Level | Level 1 (per J-STD-020) - No floor life limitation; allows indefinite storage and standard reflow without baking. |
Pinout & Package
Package: DO-214AB (SMCJ), surface-mount, bi-directional configuration with no polarity marking. Case meets UL 94 V-0 flammability rating; matte tin-plated leads comply with J-STD-002 and JESD 22-B102 solderability requirements.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (Anode) | Bi-directional surge path terminal | Both terminals function identically; no cathode band marking - enables symmetric placement across differential or AC lines. |
| Anode (Cathode) | Bi-directional surge path terminal | Electrically identical to opposite terminal; bidirectional conduction ensures protection regardless of transient polarity. |
Key Features

| RoHS-compliant E3 suffix | Meets JESD 201 Class 1A whisker resistance; suitable for high-reliability industrial and automotive PCB assemblies. |
Applications
| Automotive Sensor Protection | Industrial RS-485 Interface |
|---|---|
Use Scenario: Protecting wheel speed, crankshaft, or camshaft position sensors from load dump and inductive switching transients in 12 V vehicle systems. IC Role / Device Role / Timing Role: Bi-directional TVS placed across sensor output line and ground to clamp ±100 V transients within 1 ns response time.

IC Role / Device Role / Timing Role: Placed differentially between A/B lines and common-mode to ground to absorb common-mode ESD and lightning-induced surges. Use Value: Maintains data integrity by limiting common-mode voltage excursion to <10.3 V, preventing receiver input stage saturation or latch-up. |
| Consumer Power Adapter Input | Telecom Line Card Surge Protection |
Use Scenario: Secondary-side overvoltage suppression on 5–12 V DC outputs of wall adapters subjected to capacitor discharge or hot-plug events. IC Role / Device Role / Timing Role: Connected between VOUT and GND to clamp transient spikes generated by output capacitor discharge into shorted loads.

IC Role / Device Role / Timing Role: Installed across tip/ring pair to divert >1 kV, 10/1000 µs surges before reaching SLIC and codec ICs. Use Value: Absorbs 1500 W peak pulse energy while maintaining clamping below 10.3 V, preserving voice channel fidelity and preventing codec latch-up. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.0CA-E3/61T | Lower PPPM (400 W), smaller SMA package (DO-214AC), higher VC (10.5 V at 38.9 A) | Not suitable for high-energy automotive transients; limited to low-power consumer interfaces | Select when board space is constrained and surge energy is ≤400 W (e.g., USB port protection). |
| 1.5KE6.8CA | Through-hole TO-218 package, same VWM (6.8 V), higher VC (11.5 V at 130 A), lower thermal resistance | Requires through-hole assembly; better for high-reliability industrial power supplies with heatsinking | Choose when legacy through-hole design or enhanced thermal dissipation is required over SMT footprint. |
Compared with SMAJ6.0CA-E3/61T and 1.5KE6.8CA, the SMCJ6.0C-E3/9AT uniquely balances 1500 W surge capability, AEC-Q101 qualification, and SMT manufacturability in DO-214AB - making it optimal for automotive and industrial surface-mount systems requiring robust bi-directional clamping without layout redesign.

FAQ
What does the "C" suffix indicate in SMCJ6.0C-E3/9AT?
The "C" suffix in SMCJ6.0C-E3/9AT denotes bi-directional functionality - meaning the device provides symmetrical transient voltage suppression in both polarities. Unlike uni-directional variants (e.g., SMCJ6.0A), the SMCJ6.0C-E3/9AT has no cathode marking and clamps equally for positive and negative surges, making it ideal for AC-coupled or floating signal lines where polarity is undefined.
Is SMCJ6.0C-E3/9AT qualified for automotive applications?
Yes, SMCJ6.0C-E3/9AT is AEC-Q101 qualified, confirming its reliability for automotive electronics including engine control modules, body electronics, and ADAS sensor interfaces. This qualification covers stress testing for temperature cycling, humidity, mechanical shock, and surge immunity - validating its use in under-hood and cabin environments per ISO 16750 and ISO 7637-2 requirements.
What is the clamping voltage of SMCJ6.0C-E3/9AT and why does it matter?
The clamping voltage (VC) of SMCJ6.0C-E3/9AT is 10.3 V at 145.6 A peak pulse current (IPPM). This value represents the maximum voltage seen by protected circuitry during a 1500 W, 10/1000 µs transient. A low VC relative to VWM (clamping ratio ~1.72) ensures downstream ICs experience minimal overvoltage stress, reducing risk of latch-up, gate oxide damage, or functional interruption in sensitive microcontrollers and transceivers.
How does the DO-214AB package of SMCJ6.0C-E3/9AT affect thermal performance?
The DO-214AB (SMCJ) package of SMCJ6.0C-E3/9AT provides RθJA = 75 °C/W and RθJL = 15 °C/W when mounted on 8.0 mm × 8.0 mm copper pads per terminal. This thermal profile supports sustained 6.5 W power dissipation at TA = 50 °C and enables reliable operation up to TJ = +150 °C - critical for automotive and industrial applications where ambient temperatures exceed 85 °C and airflow is limited.
Can SMCJ6.0C-E3/9AT replace SMCJ6.0A-E3/9AT in a design?
No - SMCJ6.0C-E3/9AT and SMCJ6.0A-E3/9AT are not interchangeable without circuit review. The "C" version is bi-directional with no polarity marking and symmetrical clamping; the "A" version is uni-directional with a cathode band and only clamps in reverse bias. Substituting one for the other may result in failure to suppress positive-going transients (if using "A") or unintended forward conduction (if using "C" in DC-biased paths).
