Product details
Overview
SMCJ6.0CAHE3_A/H from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for robust overvoltage protection of sensitive electronics. 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), clamping voltage of 10.3 V at 145.6 A, and operates across -55 °C to +150 °C junction temperature range - deployed in automotive sensor signal lines and industrial I/O interfaces.
For engineers reviewing the SMCJ6.0CAHE3_A/H datasheet, SMCJ6.0CAHE3_A/H pinout, SMCJ6.0CAHE3_A/H application, or SMCJ6.0CAHE3_A/H equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, 1500 W surge rating, low clamping ratio (VC/VWM ≈ 1.72), and compatibility with automated SMT assembly on standard 8 mm × 8 mm copper pads.
Technical Context
This TVS diode uses a glass-passivated silicon junction optimized for fast response (<1 ps) to ESD and lightning-induced transients. Its bidirectional architecture enables symmetrical clamping in both polarities without polarity marking, supporting protection of AC-coupled or differential signal paths such as CAN bus stubs and RS-485 lines.
The device meets MSL Level 1 per J-STD-020 (peak reflow 260 °C), has matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, and exhibits a low incremental surge resistance - critical for minimizing let-through energy during high-current surges up to 145.6 A (10/1000 μs).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - maximum continuous reverse operating voltage before clamping begins; sets threshold for protection activation in normal operation. |
| VBR (min/max) | 6.67 V / 7.37 V at 10 mA - verified breakdown range ensures reliable turn-on margin above VWM while avoiding false triggering. |
| VC @ IPPM | 10.3 V at 145.6 A - clamping voltage under full 1500 W surge defines worst-case voltage seen by protected circuitry. |
| PPPM | 1500 W - peak pulse power handling (10/1000 μs waveform) determines survivability against IEC 61000-4-5 Level 4 surges. |
| TJ Range | -55 °C to +150 °C - extended thermal range supports under-hood automotive and industrial environments without derating. |
| Package | SMC (DO-214AB) - surface-mount outline with 7.75 mm × 6.22 mm footprint and 2.62 mm height, compatible with standard SMT pick-and-place. |
Pinout & Package
SMCJ6.0CAHE3_A/H is a two-terminal bidirectional TVS diode in SMC (DO-214AB) package. No polarity marking is present; both terminals are functionally symmetric. The device mounts using matte tin-plated leads soldered to 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal for optimal thermal and surge current handling.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry (negative half-cycle) | Accepts reverse surge current during negative transients; forms one side of symmetrical clamping path. |
| Cathode | Transient current entry (positive half-cycle) | Accepts reverse surge current during positive transients; completes bidirectional conduction path with Anode. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control modules and ADAS sensor interfaces per stress test requirements. |
| 1500 W peak pulse power | Withstands IEC 61000-4-5 combination wave surges (42 Ω/12 Ω source) up to Level 4 (4 kV line-earth, 2 kV line-line) without degradation. |
| Bidirectional clamping | Enables single-device protection of AC signals, differential buses (e.g., CAN, RS-485), and ungrounded circuits without polarity concerns. |
| Low clamping ratio (VC/VWM = 1.72) | Minimizes let-through overvoltage during surge events, reducing stress on downstream ICs like microcontrollers and transceivers. |
Applications
| Automotive Sensor Protection | Industrial I/O Interface |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.0AHE3_A/H | Lower PPPM (400 W), smaller SMA package (DO-214AC), higher RθJA (110 °C/W) | Suitable only for lower-energy threats (IEC 61000-4-2 ESD, not IEC 61000-4-5 surges) | Select when board space is constrained and surge threat level is limited to ESD-only environments. |
| SMCJ6.0CAHM3_A/H | Halogen-free construction, identical electrical specs and AEC-Q101 qualification | Required for RoHS-compliant, halogen-free BOMs in automotive Tier-1 supply chains | Choose when compliance with JEDEC J-STD-609 Class 2a (halogen-free) is mandated. |

The SMCJ6.0CAHE3_A/H has a maximum clamping voltage (VC) of 10.3 V when subjected to its peak pulse current (IPPM) of 145.6 A under a 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during a full-rated surge event. The SMCJ6.0CAHE3_A/H maintains this clamping performance across its full operating temperature range.
Is SMCJ6.0CAHE3_A/H suitable for automotive applications?
Yes, SMCJ6.0CAHE3_A/H is AEC-Q101 qualified and explicitly designated for automotive use with ordering code suffix "HE3". It meets stress test requirements for temperature cycling, humidity bias, and mechanical shock, and is deployed in engine control units, ADAS camera modules, and body electronics. The SMCJ6.0CAHE3_A/H also complies with JESD201 Class 2 whisker testing and UL 497B recognition for protector classification.
How does the bidirectional design of SMCJ6.0CAHE3_A/H affect its PCB layout?
The SMCJ6.0CAHE3_A/H has no polarity marking and functions identically in both directions, eliminating orientation constraints during placement. This simplifies PCB layout for AC-coupled or differential signal paths - such as CAN H/L or RS-485 A/B - and avoids errors from incorrect cathode alignment. The SMCJ6.0CAHE3_A/H requires symmetric 8.0 mm × 8.0 mm copper pads per terminal to maintain specified thermal and surge performance.
What is the maximum operating temperature for SMCJ6.0CAHE3_A/H?
The SMCJ6.0CAHE3_A/H has a maximum junction temperature (TJ) of +150 °C and a storage temperature range of -55 °C to +150 °C. Its thermal resistance from junction to ambient (RθJA) is 75 °C/W when mounted on the recommended 0.31" × 0.31" copper pads. Derating curves in the datasheet show that SMCJ6.0CAHE3_A/H retains full 1500 W surge capability up to 85 °C ambient, with linear derating beyond that point.
Does SMCJ6.0CAHE3_A/H meet RoHS and lead-free soldering requirements?
Yes, SMCJ6.0CAHE3_A/H is RoHS-compliant and rated for lead-free reflow soldering with a maximum peak temperature of 260 °C (MSL Level 1 per J-STD-020). Its matte tin-plated leads meet J-STD-002 and JESD 22-B102 solderability standards, and the device passes JESD201 Class 2 whisker testing. The "HE3" suffix confirms commercial-grade RoHS compliance and AEC-Q101 qualification for SMCJ6.0CAHE3_A/H.
