Product details
Overview
SMBJ60CAHE3_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 60 V standoff voltage (VWM), 66.7–73.7 V breakdown voltage (VBR) at 1 mA, 96.8 V maximum clamping voltage (VC) at 6.2 A peak pulse current (IPPM), and 600 W peak pulse power (10/1000 µs waveform), used in automotive-grade protection of CAN bus interfaces, sensor supply rails, and industrial I/O modules.
For engineers reviewing the SMBJ60CAHE3_B/I datasheet, SMBJ60CAHE3_B/I pinout, SMBJ60CAHE3_B/I application, or SMBJ60CAHE3_B/I equivalent, this device is selected for robust ESD and surge immunity in AEC-Q101-compliant systems where bidirectional clamping, low clamping ratio (VC/VBR ≈ 1.45), and MSL Level 1 reflow compatibility are critical design requirements.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, with identical VBR min/max and VC specifications in forward and reverse directions. Its glass-passivated junction ensures stable leakage (<1 µA at VWM) and fast response time (<1 ns), enabling suppression of EFT bursts and lightning-induced surges per IEC 61000-4-2/4-4/4-5.
The device is rated for TJ = –55 °C to +150 °C operation, derated above 25 °C per Fig. 2, and achieves thermal resistance RθJA = 100 °C/W on standard 0.2" × 0.2" copper pads - confirming suitability for compact PCB layouts without forced cooling in automotive body control modules and industrial PLC inputs.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| VBR (min/max) | 66.7 V / 73.7 V at 1 mA - Confirmed breakdown threshold range; ensures reliable triggering above nominal rail while avoiding false trips. |
| VC @ IPPM | 96.8 V at 6.2 A - Clamped voltage during 10/1000 µs surge; limits downstream IC stress to <100 V in 48 V supply protection. |
| PPPM | 600 W - Peak pulse power handling capability; supports IEC 61000-4-5 Level 4 (4 kV line-to-line) surge testing. |
| ID @ VWM | ≤1 µA - Ultra-low reverse leakage at rated standoff; prevents excessive quiescent current in battery-powered sensor nodes. |
| TJ max. | +150 °C - Junction temperature limit; enables deployment in under-hood automotive environments and high-ambient industrial enclosures. |

FAQ
What is the clamping voltage of SMBJ60CAHE3_B/I at its rated peak pulse current?
The SMBJ60CAHE3_B/I has a maximum clamping voltage (VC) of 96.8 V at its rated peak pulse current (IPPM) of 6.2 A under a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and confirms the device's ability to limit transient overvoltage to a predictable level during surge events, directly protecting downstream components such as CAN transceivers or microcontrollers connected to the same rail.
Is SMBJ60CAHE3_B/I suitable for automotive applications?
Yes, SMBJ60CAHE3_B/I is AEC-Q101 qualified (indicated by the HE3 suffix) and rated for operation from –55 °C to +150 °C. It meets automotive reliability requirements including temperature cycling, humidity testing, and surge immunity, making it appropriate for use in body control modules, ADAS sensor interfaces, and infotainment power supplies where bidirectional transient suppression is needed.
How does the bidirectional configuration of SMBJ60CAHE3_B/I affect its circuit implementation?
The bidirectional configuration of SMBJ60CAHE3_B/I means it conducts identically in both polarities - no cathode band marking is present, and either terminal can connect to any side of the protected line. This simplifies layout for differential signal protection (e.g., CAN, RS-485) and eliminates orientation errors during automated assembly, unlike unidirectional variants which require strict anode/cathode placement relative to ground.
What is the maximum reverse leakage current of SMBJ60CAHE3_B/I at its standoff voltage?
The SMBJ60CAHE3_B/I exhibits a maximum reverse leakage current (ID) of 1 µA at its 60 V standoff voltage (VWM), measured at 25 °C. This ultra-low leakage ensures minimal impact on battery-powered or high-impedance sensor circuits, preserving signal integrity and extending operational life in always-on automotive and IoT edge devices where quiescent current must remain below microamp thresholds.
Does SMBJ60CAHE3_B/I require special PCB layout considerations for thermal performance?
Yes - to achieve the rated 600 W peak pulse power and thermal resistance (RθJA = 100 °C/W), SMBJ60CAHE3_B/I must be mounted on the minimum recommended copper pad layout: 0.2" × 0.2" (5.0 mm × 5.0 mm) pads per terminal. Reducing pad size or using thinner copper layers will increase junction temperature during surge events and may cause premature failure; verified layout data is provided in Vishay document 88392, page 5.
