Product details
Overview
SMBJ60AHM3/H from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode designed for robust overvoltage protection of sensitive electronics. It features a 60 V standoff voltage (VWM), 66.7–73.7 V breakdown voltage (VBR) at 1 mA, 600 W peak pulse power (10/1000 µs), and clamps transients to ≤96.8 V at 6.2 A, making it suitable for protecting MOSFETs, ICs, and sensor signal lines in industrial power supplies.
For engineers reviewing the SMBJ60AHM3/H datasheet, SMBJ60AHM3/H pinout, SMBJ60AHM3/H application, or SMBJ60AHM3/H equivalent, key selection criteria include its halogen-free RoHS-compliant SMB (DO-214AA) package, AEC-Q101 qualification status, unidirectional polarity with cathode band marking, and thermal resistance (RθJA = 100 °C/W) under standard PCB pad layout.
Technical Context
This TVS diode operates as a clamping device that remains high-impedance below VWM = 60 V and rapidly transitions to low-impedance conduction above VBR = 66.7–73.7 V to divert surge current. Its glass-passivated junction ensures stable avalanche characteristics and fast response time (<1 ns), while the 10/1000 µs waveform rating reflects standardized lightning/surge immunity testing per ANSI/IEEE C62.35.
The SMBJ60AHM3/H is rated for repetitive surges at 0.01% duty cycle and supports peak forward surge current (IFSM) up to 100 A (8.3 ms half-sine), with maximum junction temperature of +150 °C and storage range from –55 °C to +150 °C. Its M3 suffix confirms halogen-free, RoHS-compliant construction meeting JESD201 Class 2 whisker resistance.

FAQ
What is the clamping voltage of SMBJ60AHM3/H at its rated peak pulse current?
The SMBJ60AHM3/H has a maximum clamping voltage (VC) of 96.8 V at its rated peak pulse current (IPPM) of 6.2 A, measured using the standardized 10/1000 µs waveform. This value ensures predictable voltage limiting during surge events and is confirmed in the Vishay SMBJ5.0A–SMBJ188A datasheet (Document Number: 88392, Rev. 09-Jan-2024). The SMBJ60AHM3/H maintains this clamping performance across its specified operating temperature range.
Is SMBJ60AHM3/H certified for automotive applications?
Yes, SMBJ60AHM3/H is AEC-Q101 qualified, as indicated by the "HM3" suffix in its part number. This certification validates its reliability for automotive use cases including temperature cycling, highly accelerated life testing (HALT), and ESD stress per the AEC-Q101 stress test plan. The SMBJ60AHM3/H is specifically intended for body electronics, infotainment, and powertrain subsystems where transient immunity and long-term stability are required.
What does the "HM3" suffix signify in SMBJ60AHM3/H?
The "HM3" suffix in SMBJ60AHM3/H denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification. It distinguishes this variant from E3 (RoHS only) and HE3 (RoHS + AEC-Q101) versions. The "H" indicates the halogen-free formulation, and "M3" confirms compliance with JESD201 Class 2 whisker resistance and JEDEC moisture sensitivity level (MSL) 1, supporting lead-free reflow up to 260 °C.
Can SMBJ60AHM3/H be used in bidirectional protection circuits?
No, SMBJ60AHM3/H is a unidirectional TVS diode, as confirmed by its part number structure and datasheet specifications. Bidirectional variants use the "CA" suffix (e.g., SMBJ60CA). Using SMBJ60AHM3/H in bidirectional applications would result in forward conduction during negative transients, potentially damaging the device or failing to protect the circuit. Always verify polarity marking-the cathode band on SMBJ60AHM3/H must face the higher-potential node.
What is the maximum reverse leakage current of SMBJ60AHM3/H at its standoff voltage?
The SMBJ60AHM3/H exhibits a maximum reverse leakage current (ID) of 1.0 µA at its rated standoff voltage (VWM) of 60 V and ambient temperature of 25 °C. This low leakage ensures minimal power loss in always-on systems and preserves signal integrity on high-impedance nodes such as sensor inputs or reset lines. Leakage remains within specification up to +125 °C, per the device's thermal derating curve.
