Product details
Overview
SMCJ6.0A-E3/9AT from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for clamping voltage transients up to 1500 W peak pulse power with 10.3 V maximum clamping voltage at 145.6 A peak pulse current and 6.0 V stand-off voltage. It protects MOSFETs, ICs, and sensor signal lines in automotive and industrial power electronics.
For engineers reviewing the SMCJ6.0A-E3/9AT datasheet, SMCJ6.0A-E3/9AT pinout, SMCJ6.0A-E3/9AT application, or SMCJ6.0A-E3/9AT equivalent, key selection criteria include unidirectional polarity, 6.67–7.37 V breakdown voltage range at 10 mA test current, 1000 μA max reverse leakage at 6.0 V, and AEC-Q101 qualification eligibility via HE3 suffix variants.
Technical Context
The SMCJ6.0A-E3/9AT operates as a silicon avalanche diode with glass-passivated junction, delivering fast response time (<1 ns) and low incremental surge resistance to suppress ESD and inductive switching transients. Its unidirectional configuration uses cathode-band marking and exhibits 0.059 %/°C temperature coefficient of breakdown voltage.
Designed for PCB-level protection on DC power rails and low-speed signal lines, it complies with UL 497B recognition (QVGQ2), meets J-STD-020 MSL Level 1, and supports reflow soldering up to 260 °C peak. Thermal resistance is 75 °C/W junction-to-ambient on standard 8.0 mm × 8.0 mm copper pads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Stand-off Voltage (VWM) | 6.0 V - Maximum continuous reverse operating voltage before significant conduction begins |
| Breakdown Voltage (VBR) | 6.67–7.37 V at 10 mA - Confirmed avalanche onset range under standardized test conditions |
| Clamping Voltage (VC) | 10.3 V at 145.6 A IPPM - Peak voltage seen by protected circuit during 10/1000 μs surge |
| Peak Pulse Power (PPPM) | 1500 W - Surge energy handling capability per single 10/1000 μs waveform |
| Reverse Leakage (ID) | 1000 μA max at VWM - Low standby current ensuring minimal power loss in normal operation |
| Junction Temp Range | −55 to +150 °C - Enables use in under-hood automotive and industrial ambient environments |
| Package | SMC (DO-214AB) - Standardized surface-mount outline with 7.75 mm × 6.22 mm footprint and 2.62 mm height |
Pinout & Package
SMCJ6.0A-E3/9AT uses the SMC (DO-214AB) package: a two-terminal, non-polarized surface-mount outline with matte tin-plated leads, 0.260–0.280 inch (6.60–7.11 mm) body length, and cathode band marking on the unidirectional variant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Anode-side connection point in reverse-biased protection mode | Connected to protected line; conducts when transient exceeds VWM, shunting surge to ground |
| Anode (non-banded end) | Reference/ground return path | Typically tied to system ground or low-impedance return plane to complete clamping current path |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable avalanche characteristics and long-term reliability under repeated surge stress |
| Low-profile SMC package | Enables automated placement and high-density PCB layouts without compromising thermal performance |
| 1500 W peak pulse rating | Provides robust protection against IEC 61000-4-5 Level 4 (4 kV) surges on 12 V/24 V systems |
| AEC-Q101 qualification path | Supports automotive-grade sourcing via HE3/HM3 suffix variants with full qualification documentation |
| UL 497B recognized (QVGQ2) | Validates suitability for telecom and industrial communication interface protection per safety standards |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.0A-E3/61T | Lower PPPM (400 W), smaller SMA package, same VWM/VBR range | Not suitable for 1500 W surge events; limited to lower-energy interfaces like USB or GPIO | Select only when board space is constrained and surge threat level is ≤IEC 61000-4-2 Level 3 |
| SMCJ6.0CA-E3/9AT | Bidirectional version; identical VWM/VBR but symmetrical clamping in both polarities | Required for AC-coupled or floating signal lines where polarity reversal may occur | Choose when protecting differential buses (e.g., CAN, RS-485) without defined DC bias reference |
Compared with SMCJ6.0A-E3/9AT, SMAJ6.0A-E3/61T trades surge capacity for footprint reduction, while SMCJ6.0CA-E3/9AT adds bidirectional symmetry at no cost to clamping performance-making each alternative optimal only within its specific circuit context.

FAQ
What is the breakdown voltage range of the SMCJ6.0A-E3/9AT?
The SMCJ6.0A-E3/9AT has a guaranteed breakdown voltage range of 6.67 V to 7.37 V at 10 mA test current (IT), measured per ANSI/IEEE C62.35. This range ensures consistent avalanche initiation across production lots and temperature extremes, directly supporting reliable clamping behavior in the SMCJ6.0A-E3/9AT's intended protection applications.
Is the SMCJ6.0A-E3/9AT suitable for automotive applications?
The SMCJ6.0A-E3/9AT itself is RoHS-compliant commercial grade (E3 suffix), but Vishay offers AEC-Q101-qualified versions under HE3 suffix (e.g., SMCJ6.0AHE3_A/I). The SMCJ6.0A-E3/9AT shares identical electrical and thermal specs with those qualified variants, allowing direct design-in where qualification is not mandated-though full AEC-Q101 compliance requires the HE3/HM3 ordering code for SMCJ6.0A-E3/9AT-equivalent performance.
How does the clamping voltage of SMCJ6.0A-E3/9AT compare to its stand-off voltage?
The SMCJ6.0A-E3/9AT clamps at 10.3 V under 145.6 A peak pulse current (10/1000 μs waveform), which is 71.7% higher than its 6.0 V stand-off voltage. This ratio reflects the device's ability to remain non-conductive during normal operation while limiting transient overvoltage to a safe margin-critical for protecting 5 V or 3.3 V logic interfaces downstream of the SMCJ6.0A-E3/9AT.
What is the thermal resistance of SMCJ6.0A-E3/9AT in typical PCB mounting?
The SMCJ6.0A-E3/9AT has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal. This value assumes standard FR-4 PCB construction and defines the steady-state temperature rise under 6.5 W continuous power dissipation-important for derating calculations in high-ambient industrial environments where the SMCJ6.0A-E3/9AT operates.
Does SMCJ6.0A-E3/9AT have UL recognition?
Yes, the SMCJ6.0A-E3/9AT carries Underwriters Laboratories recognition under file number E136766 for both unidirectional and bidirectional configurations, compliant with UL 497B for protectors. This certification validates its use in telecom and industrial equipment requiring third-party safety approval-confirming that the SMCJ6.0A-E3/9AT meets recognized surge protection safety requirements beyond basic datasheet specifications.
