Product details
Overview
SMBJ6.0CAHE3_B/I from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on power and signal lines. It features 6.4 V minimum breakdown voltage (VBR), 6.0 V maximum stand-off voltage (VWM), 600 W peak pulse power (10/1000 µs), 58.3 A peak pulse current (IPPM), and 10.3 V maximum clamping voltage (VC) - deployed in automotive sensor protection and industrial I/O interface circuits.
For engineers reviewing the SMBJ6.0CAHE3_B/I datasheet, SMBJ6.0CAHE3_B/I pinout, SMBJ6.0CAHE3_B/I application, or SMBJ6.0CAHE3_B/I equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), junction temperature range (–55 to +150 °C), and bidirectional clamping behavior under transient surge conditions.
Technical Context
This TVS diode operates as a voltage-clamping protection device across bidirectional signal or DC power rails. Its glass-passivated junction enables fast response (<1 ns), low incremental surge resistance, and stable clamping performance over repeated 10/1000 µs transients at 0.01% duty cycle.
The SMBJ6.0CAHE3_B/I is rated for 5.0 W steady-state power dissipation at TA = 50 °C, with thermal resistance from junction to ambient of 100 °C/W and junction-to-lead of 20 °C/W. It meets MSL Level 1 per J-STD-020 and supports lead-free reflow up to 260 °C peak.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 6.4 V to 7.07 V at IT = 10 mA - defines reliable conduction onset under bidirectional surge |
| VWM | 6.0 V - maximum continuous reverse voltage before leakage exceeds 800 µA |
| VC @ IPPM | 10.3 V at 58.3 A (10/1000 µs) - clamped voltage seen by protected IC during worst-case surge |
| PPPM | 600 W - peak transient energy absorption capability without failure |
| IPPM | 58.3 A - maximum non-repetitive surge current the device safely diverts |
| TJ Range | –55 °C to +150 °C - operational junction temperature window for automotive and industrial use |
| RθJA | 100 °C/W - thermal resistance limiting power derating above 25 °C ambient |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, bidirectional configuration with no polarity marking. Matte tin-plated leads, RoHS-compliant and AEC-Q101 qualified (HE3 suffix). Molding compound meets UL 94 V-0.

Applications
| Automotive Sensor Interface | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor inputs (e.g., pressure, temperature) from load dump and ESD events in vehicle ECUs. IC Role / Device Role / Timing Role: Bidirectional voltage clamp placed across differential or single-ended signal lines upstream of receiver input. Use Value: Limits transient voltage to ≤10.3 V, preventing damage to 5 V tolerant transceivers while maintaining signal integrity during 58.3 A surges. |
Use Scenario: Safeguarding 24 V digital input modules in programmable logic controllers against field-wiring induced surges and inductive kickback. IC Role / Device Role / Timing Role: Parallel-connected TVS on each input channel, referenced to common ground, absorbing energy before it reaches optocoupler or Schmitt trigger inputs. Use Value: Clamps 600 W transients within 1 ns, enabling compliance with IEC 61000-4-4 (EFT) and IEC 61000-4-5 (surge) immunity standards. |
| Consumer Power Adapter Output | Telecom Line Card Surge Protection |
Use Scenario: Secondary-side overvoltage suppression on 5 V/9 V USB-C PD adapter outputs exposed to accidental short-circuit recovery spikes. IC Role / Device Role / Timing Role: Bidirectional clamp between VOUT and GND, activated only during abnormal overvoltage excursions beyond 6.0 V. Use Value: Prevents latch-up or gate oxide rupture in downstream USB port controllers by holding output below 10.3 V during 10/1000 µs surges. |
Use Scenario: Front-end protection on telecom line cards handling analog voice or DSL signals subject to lightning-induced longitudinal surges. IC Role / Device Role / Timing Role: Paired bidirectional TVS devices across tip/ring lines, providing symmetric clamping without polarity dependency. Use Value: Delivers matched 6.4–7.07 V breakdown in both directions, ensuring balanced protection and minimal signal distortion on AC-coupled lines. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.0CA-E3/52 | Same electrical specs, but commercial-grade (non-AEC-Q101), RoHS-compliant, 7" tape/reel (750 pcs) | Lacks automotive qualification; suitable for consumer/industrial designs without AEC requirements | Select when cost sensitivity outweighs automotive reliability validation needs |
| SAC6.0 | Lower 400 W PPPM, higher VC = 12.5 V at 32.5 A, SOD-123FL package (smaller footprint) | Reduced surge margin; limited to lower-energy transients and space-constrained PCBs | Choose only if board area is critical and surge threat level is ≤IEC 61000-4-5 Level 2 |
Compared with SMBJ6.0CAHE3_B/I, the SMBJ6.0CA-E3/52 offers identical clamping and breakdown but omits AEC-Q101 validation-making it viable for non-automotive use. The SAC6.0 trades 33% lower pulse power and higher clamping voltage for 40% smaller footprint, requiring careful system-level surge margin analysis.

FAQ
What is the breakdown voltage tolerance for SMBJ6.0CAHE3_B/I?
The SMBJ6.0CAHE3_B/I has a specified breakdown voltage (VBR) range of 6.4 V to 7.07 V at test current IT = 10 mA. This ±5.5% tolerance ensures consistent clamping onset across production lots while accommodating process variation and temperature drift up to +150 °C junction temperature.
Is SMBJ6.0CAHE3_B/I suitable for automotive applications?
Yes, SMBJ6.0CAHE3_B/I is AEC-Q101 qualified (denoted by HE3 suffix) and rated for –55 °C to +150 °C operating junction temperature. It is validated for use in automotive subsystems including body control modules, ADAS sensor interfaces, and infotainment power rails where transient immunity and long-term reliability are critical.
What does the "CA" suffix indicate in SMBJ6.0CAHE3_B/I?
The "CA" suffix in SMBJ6.0CAHE3_B/I designates a bidirectional configuration - meaning the device provides symmetrical transient suppression in both polarities, with identical VBR, VC, and IPPM characteristics regardless of voltage polarity applied. This eliminates need for polarity-aware layout in AC or differential signal paths.
How does SMBJ6.0CAHE3_B/I compare to unidirectional SMBJ6.0AHE3_B/I?
SMBJ6.0CAHE3_B/I differs from SMBJ6.0AHE3_B/I solely in polarity: CA is bidirectional (no cathode band, symmetrical clamping), while A is unidirectional (cathode-banded, conducts only in reverse bias). Both share identical VWM = 6.0 V, PPPM = 600 W, and VC = 10.3 V, but SMBJ6.0CAHE3_B/I is required for AC-coupled or floating-line protection.
What is the maximum allowable mounting pad size for SMBJ6.0CAHE3_B/I per datasheet?
Per Vishay document 88392, the recommended copper pad layout for SMBJ6.0CAHE3_B/I is 0.2" × 0.2" (5.0 mm × 5.0 mm) per terminal to achieve rated 600 W peak pulse power and thermal performance. Smaller pads reduce IPPM capability and increase junction temperature rise during surge events.
