Product details
Overview
SMBJ60CHE3/52 from Vishay General Semiconductor is a unidirectional 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, 600 W peak pulse power (10/1000 µs), 6.2 A peak pulse current (IPPM), and 96.8 V maximum clamping voltage (VC) - deployed to protect MOSFETs, ICs, and sensor interfaces in industrial power supplies.
For engineers reviewing the SMBJ60CHE3/52 datasheet, SMBJ60CHE3/52 pinout, SMBJ60CHE3/52 application, or SMBJ60CHE3/52 equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification status, 150 °C max junction temperature, low incremental surge resistance, and compatibility with automated SMT placement on 0.2" × 0.2" copper pads.
Technical Context
This TVS diode operates as a fast-acting shunt clamp during overvoltage events, leveraging a glass-passivated silicon junction to achieve sub-nanosecond response time. Its unidirectional configuration enables integration into DC power rails and single-polarity signal paths where reverse conduction must be blocked.
The device complies with IEC 61000-4-2 (ESD), IEC 61000-4-4 (EFT), and IEC 61000-4-5 (surge) immunity requirements when applied with proper PCB layout. Thermal resistance is specified at RθJA = 100 °C/W (on recommended pad layout) and RθJL = 20 °C/W, supporting reliable operation up to 150 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 60 V - maximum continuous reverse operating voltage before clamping begins; defines safe DC bias margin for 48 V systems. |
| VBR (min/max) | 66.7 V / 73.7 V at IT = 1 mA - ensures predictable turn-on threshold across manufacturing lot and temperature range. |
| VC @ IPPM | 96.8 V - clamped voltage during 6.2 A 10/1000 µs transient; determines protected circuit's maximum stress level. |
| PPPM | 600 W - peak pulse power handling capability under standardized surge waveform; validates robustness against lightning-induced surges. |
| IPPM | 6.2 A - maximum non-repetitive surge current supported; used to size upstream fusing and trace width. |
| TJ max | 150 °C - maximum junction temperature rating; enables use in under-hood automotive and high-ambient industrial environments. |

FAQ
What is the polarity configuration of SMBJ60CHE3/52?
SMBJ60CHE3/52 is a unidirectional TVS diode, with the cathode identified by a band on the SMB (DO-214AA) package body. This configuration allows it to conduct only during positive transients on the cathode side relative to anode, making it ideal for DC power rail protection where reverse voltage blocking is required. The device does not conduct in reverse bias below VWM = 60 V.
Is SMBJ60CHE3/52 qualified to AEC-Q101?
Yes, SMBJ60CHE3/52 is explicitly AEC-Q101 qualified, as confirmed by Vishay's ordering code suffix "HE3" and documentation in datasheet 88392 (Revision 09-Jan-2024). This qualification covers stress tests including temperature cycling, high-temperature reverse bias, and ESD - validating its suitability for automotive electronic control units and ADAS subsystems.
What is the maximum clamping voltage of SMBJ60CHE3/52 at rated surge current?
The maximum clamping voltage (VC) of SMBJ60CHE3/52 is 96.8 V at IPPM = 6.2 A, measured under the standard 10/1000 µs double-exponential surge waveform. This value defines the upper voltage limit imposed on protected circuitry during worst-case transient events and is critical for ensuring compatibility with downstream components' absolute maximum ratings.
Can SMBJ60CHE3/52 be used in bidirectional applications?
No, SMBJ60CHE3/52 is strictly unidirectional. For bidirectional transient suppression - such as AC signal lines or differential buses - Vishay specifies the CA-suffix variant (e.g., SMBJ60CA). Using SMBJ60CHE3/52 in bidirectional configurations would result in forward conduction during negative transients, potentially damaging the device or failing to suppress.
What is the thermal resistance and recommended mounting for SMBJ60CHE3/52?
SMBJ60CHE3/52 has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on the minimum recommended 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. Its junction-to-lead resistance (RθJL) is 20 °C/W. To maintain reliability at full power, ensure adequate copper area and avoid thermal bottlenecks in PCB layout - especially in automotive or industrial ambient temperatures exceeding 85 °C.
