Product details
Overview
SMBJ6.0CAHE3_A/H from Vishay General Semiconductor is a bidirectional surface-mount transient voltage suppressor (TVS) diode in the SMB (DO-214AA) package, designed for clamping voltage transients on signal and power lines. It features a 6.0 V stand-off voltage (VWM), 6.4–7.07 V breakdown voltage (VBR) at 10 mA, 600 W peak pulse power (10/1000 µs), and clamps to ≤10.3 V at 58.3 A peak surge current - deployed in sensor interface protection for industrial control systems.
For engineers reviewing the SMBJ6.0CAHE3_A/H datasheet, SMBJ6.0CAHE3_A/H pinout, SMBJ6.0CAHE3_A/H application, or SMBJ6.0CAHE3_A/H equivalent, this device is selected for robust ESD and lightning-induced surge suppression in bidirectional signal paths where low clamping voltage, fast response (<1 ns), and AEC-Q101 qualification are required.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, with identical electrical characteristics in forward and reverse directions. Its glass-passivated junction ensures stable breakdown behavior and low leakage (<1 µA at VWM), while the low incremental surge resistance supports consistent clamping under repetitive transients.
The device is rated for TJ = –55 °C to +150 °C and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak. Its AEC-Q101 qualification (indicated by HE3 suffix) confirms suitability for automotive electronics, including body control modules and infotainment I/O protection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - Maximum continuous reverse working voltage before clamping begins; sets operating margin above circuit nominal voltage. |
| VBR (min/max) | 6.4 V / 7.07 V at 10 mA - Confirmed breakdown range ensures reliable triggering without premature conduction. |
| VC @ IPPM | ≤10.3 V at 58.3 A - Clamping voltage limits stress on downstream ICs during 600 W transient events. |
| PPPM | 600 W (10/1000 µs waveform) - Sustains high-energy surges common in automotive load-dump and inductive switching. |
| IPPM | 58.3 A - Peak surge current capacity validated per standard waveform; defines maximum transient energy absorption. |
| TJ max. | +150 °C - Enables operation in under-hood automotive environments and thermally constrained PCB layouts. |
| Package | SMB (DO-214AA) - Surface-mount footprint (5.21 mm × 4.06 mm) compatible with automated assembly and IPC-7351B land patterns. |

FAQ
What is the clamping voltage of SMBJ6.0CAHE3_A/H at its rated peak pulse current?
The SMBJ6.0CAHE3_A/H clamps to a maximum of 10.3 V when subjected to its rated peak pulse current of 58.3 A (10/1000 µs waveform). This value is measured under standardized test conditions and defines the upper voltage limit imposed on protected circuitry during transient events. The SMBJ6.0CAHE3_A/H maintains this clamping performance across its full operating temperature range of –55 °C to +150 °C.
Is SMBJ6.0CAHE3_A/H suitable for automotive applications?
Yes, SMBJ6.0CAHE3_A/H is AEC-Q101 qualified, as confirmed by the "HE3" suffix and Vishay documentation. It undergoes rigorous stress testing including temperature cycling, high-temperature reverse bias, and surge endurance - making it appropriate for automotive subsystems such as body control modules, ADAS sensor interfaces, and infotainment I/O protection where reliability under harsh conditions is mandatory.
How does the bidirectional configuration of SMBJ6.0CAHE3_A/H affect its circuit placement?
The SMBJ6.0CAHE3_A/H has no polarity marking and functions identically in both directions, allowing placement across any two nodes requiring symmetrical overvoltage protection - such as differential signal pairs (CAN_H/CAN_L) or AC-coupled lines. Unlike unidirectional TVS diodes, it eliminates orientation concerns during automated assembly and supports protection schemes where transient polarity is unpredictable.
What is the maximum steady-state power dissipation of SMBJ6.0CAHE3_A/H?
The SMBJ6.0CAHE3_A/H has a maximum steady-state power dissipation (PD) of 5.0 W at TA = 50 °C on an infinite heatsink. In typical SMB-mounted PCB applications with 0.2" × 0.2" copper pads per terminal, thermal resistance is ~100 °C/W (junction-to-ambient), meaning sustained power must remain well below 5 W to avoid exceeding the +150 °C maximum junction temperature.
Does SMBJ6.0CAHE3_A/H meet RoHS and halogen-free requirements?
Yes, SMBJ6.0CAHE3_A/H is RoHS-compliant and AEC-Q101 qualified, as indicated by the "HE3" suffix. It is not halogen-free - that designation applies only to "HM3" variants. The device uses matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, and its molding compound meets UL 94 V-0 flammability rating.
