Product details
Overview
SMBG6.0CAHE3/52 from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMBG (DO-215AA) package, designed for clamping ESD and surge transients on signal/power lines. It features 6.0 V stand-off voltage (VWM), 6.67–7.37 V breakdown voltage (VBR) at 10 mA, 600 W peak pulse power (10/1000 μs), <10.3 V clamping voltage (VC) at 58.3 A, and AEC-Q101 qualification for automotive electronics protection.
For engineers reviewing the SMBG6.0CAHE3/52 datasheet, SMBG6.0CAHE3/52 pinout, SMBG6.0CAHE3/52 application, or SMBG6.0CAHE3/52 equivalent, key selection criteria include bidirectional clamping capability, low clamping ratio (VC/VBR ≈ 1.47), MSL Level 1 solderability, and compliance with IEC 61000-4-2 (±15 kV air/±8 kV contact) and ISO 16750-2 load dump immunity requirements.
Technical Context
This device operates as a voltage-clamped shunt protector: under normal bias it presents high impedance (<1 μA leakage at 6.0 V), but triggers into low-impedance conduction when reverse or forward transients exceed its symmetric breakdown threshold. Its glass-passivated junction ensures stable VBR tolerance (±5%) and low dynamic resistance (≈0.17 Ω derived from ΔVC/ΔIPPM).
The SMBG6.0CAHE3/52 leverages the DO-215AA package's thermal performance (RθJL = 20 °C/W) to sustain repetitive 600 W surges at 0.01% duty cycle, while its unmarked bidirectional polarity eliminates orientation concerns during automated placement on PCBs handling AC-coupled or differential signaling paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - Maximum continuous reverse/forward working voltage before clamping begins; sets safe operating margin for 5 V logic or CAN bus lines. |
| VBR (min/max) | 6.67 V / 7.37 V at 10 mA - Tight 5% tolerance ensures predictable turn-on across temperature and production lots. |
| VC @ IPPM | 10.3 V at 58.3 A - Clamping voltage limits downstream IC stress during 600 W surge; clamping ratio = 1.47. |
| PPPM | 600 W (10/1000 μs) - Sustains automotive load dump and inductive switching transients without degradation. |
| TJ range | −55 °C to +150 °C - Supports under-hood automotive environments and industrial control cabinets. |
| AEC-Q101 | Qualified - Validated for reliability in automotive powertrain, body electronics, and ADAS sensor interfaces. |

Applications
| Automotive CAN Bus Protection | Industrial Sensor Signal Lines |
|---|---|
Use Scenario: Protecting CAN_H/CAN_L differential pair against ESD (IEC 61000-4-2) and coupled transients from nearby solenoid switching. IC Role / Device Role / Timing Role: Bidirectional shunt clamp placed directly at connector entry point to divert surge energy to ground before reaching CAN transceiver. Use Value: Maintains CAN signal integrity by clamping transients to ≤10.3 V while supporting data rates up to 1 Mbps without capacitive loading penalty (CJ < 100 pF at 0 V). | Use Scenario: Safeguarding analog outputs (4–20 mA, 0–10 V) and digital I/O of pressure/temperature sensors in factory automation PLC modules. IC Role / Device Role / Timing Role: Low-leakage (≤1 μA at 6.0 V) TVS placed across sensor output pins to absorb field-induced surges without affecting calibration or offset. Use Value: Prevents false readings or latch-up in precision ADC front-ends by limiting overvoltage to <10.3 V during 600 W surges, with no DC bias impact. |
| USB 2.0 Data Line Protection | Power Supply Input Stage |
Use Scenario: ESD protection for D+/D− lines in automotive infotainment USB ports exposed to human-body-model discharges. IC Role / Device Role / Timing Role: Symmetric bidirectional clamp with matched VBR on both lines to preserve differential signaling integrity during ±8 kV contact discharge. Use Value: Achieves <1 ns response time and <100 pF junction capacitance to avoid signal rise-time degradation at 480 Mbps full-speed operation. | Use Scenario: Secondary-level surge suppression on 5 V or 3.3 V rail inputs after primary MOV/fuse stage in embedded power supplies. IC Role / Device Role / Timing Role: Fast-reacting secondary clamp that activates before downstream LDOs or DC-DC converters reach overvoltage trip thresholds. Use Value: Limits input rail overshoot to ≤10.3 V during fast 10/1000 μs transients, preventing brownout resets or internal FET avalanche in regulators. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.0CA | Same VWM/VBR/VC, but lower PPPM = 600 W (same rating) and higher IFSM = 100 A (unidirectional only); SMBJ uses DO-214AA package (larger footprint, RθJA = 110 °C/W). | Less suitable for space-constrained automotive modules where SMBG's smaller DO-215AA saves board area and improves thermal coupling. | Select SMBG6.0CAHE3/52 when PCB real estate or thermal performance in tight layouts is critical. |
| 1.5KE6.8CA | Higher PPPM = 1500 W but axial DO-15 package; VWM = 6.8 V (not identical), VC = 11.5 V at 130 A; not AEC-Q101 qualified. | Requires through-hole assembly and lacks automotive qualification; better for high-energy industrial mains protection than automotive signal lines. | Choose SMBG6.0CAHE3/52 for surface-mount automotive designs requiring AEC-Q101 and compact footprint. |
Compared with SMBJ6.0CA and 1.5KE6.8CA, the SMBG6.0CAHE3/52 delivers identical clamping performance in a smaller, thermally superior surface-mount package with automotive-grade qualification-making it optimal for space- and reliability-critical vehicle ECUs and sensor nodes.

FAQ
What is the clamping voltage of SMBG6.0CAHE3/52 and how does it protect downstream ICs?
The SMBG6.0CAHE3/52 has a maximum clamping voltage (VC) of 10.3 V at 58.3 A peak pulse current (10/1000 μs waveform). This limits transient overvoltage seen by protected circuits-such as 5 V CAN transceivers or microcontrollers-to a safe level well below their absolute maximum ratings, preventing damage or malfunction during ESD or inductive switching events. The SMBG6.0CAHE3/52 achieves this via rapid avalanche breakdown and low dynamic impedance.
Is SMBG6.0CAHE3/52 suitable for automotive applications?
Yes, SMBG6.0CAHE3/52 is AEC-Q101 qualified and rated for −55 °C to +150 °C junction temperature, making it suitable for under-hood and cabin automotive applications including CAN bus protection, sensor interface conditioning, and infotainment port ESD suppression. Its HE3 suffix explicitly denotes AEC-Q101 qualification and RoHS compliance, verified per Vishay document 88456.
What does the "CA" suffix indicate in SMBG6.0CAHE3/52?
The "CA" suffix in SMBG6.0CAHE3/52 denotes a bidirectional configuration-meaning the device provides symmetrical transient suppression for both positive and negative voltage excursions, with identical breakdown and clamping characteristics in either polarity. This eliminates polarity marking and simplifies layout for AC-coupled or differential signal lines like CAN, USB, or RS-485.
How does the SMBG (DO-215AA) package compare to SMBJ (DO-214AA) for SMBG6.0CAHE3/52?
The SMBG (DO-215AA) package used by SMBG6.0CAHE3/52 is 15% smaller in footprint than SMBJ (DO-214AA) and offers lower thermal resistance (RθJL = 20 °C/W vs. ~25 °C/W for SMBJ), improving power dissipation in dense layouts. Both support 600 W peak pulse power, but SMBG enables finer-pitch routing and better thermal coupling to PCB copper pads-critical for automotive module miniaturization.
What is the maximum leakage current of SMBG6.0CAHE3/52 at its stand-off voltage?
The SMBG6.0CAHE3/52 exhibits a maximum reverse leakage current (ID) of 800 μA at its 6.0 V stand-off voltage (VWM) and 25 °C ambient temperature. This low leakage ensures minimal power loss and no interference with sensitive analog or low-power digital circuits during normal operation, while still enabling fast, low-threshold clamping during transients.
