Product details
Overview
SMBJ60AHM3_A/H from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed to protect sensitive electronics against voltage transients induced by inductive load switching and lightning surges. It features a 60 V stand-off 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, and 600 W peak pulse power rating with 10/1000 µs waveform.
For engineers reviewing the SMBJ60AHM3_A/H datasheet, SMBJ60AHM3_A/H pinout, SMBJ60AHM3_A/H application, or SMBJ60AHM3_A/H equivalent, this device is selected for robust overvoltage protection in DC power rails, I/O interfaces, and sensor signal lines where fast response (<1 ns), low clamping ratio, and AEC-Q101 qualification are required.
Technical Context
This TVS diode operates as a unidirectional avalanche clamp, conducting only when reverse voltage exceeds VBR, with cathode band marking polarity. Its junction structure is glass passivated for stable leakage performance and reliability under repetitive surge stress.
Thermal design relies on RθJA = 100 °C/W (typ.) and RθJL = 20 °C/W (typ.), requiring minimum 5.0 mm × 5.0 mm copper pads per terminal for rated 600 W pulse handling. It meets MSL Level 1 per J-STD-020 and supports lead-free reflow up to 260 °C peak.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 60 V - Maximum continuous reverse operating voltage before significant leakage begins; defines safe DC rail protection threshold. |
| VBR (min/max) | 66.7 V / 73.7 V at 1 mA - Confirmed breakdown range ensures reliable triggering margin above VWM without premature conduction. |
| VC @ IPPM | 96.8 V at 6.2 A - Clamping voltage during 10/1000 µs surge; limits downstream IC stress to ≤96.8 V under full-rated transient. |
| PPPM | 600 W - Peak pulse power capability with 0.01% duty cycle; enables protection against high-energy transients like ISO 7637-2 Pulse 1/2a/5a. |
| IFSM | 100 A - Non-repetitive forward surge current rating (8.3 ms half-sine); supports robustness against accidental reverse-bias misapplication. |
| TJ max | +150 °C - Maximum junction temperature; allows operation in under-hood automotive environments and industrial enclosures. |
| Leakage ID | 1.0 µA max @ 60 V - Ultra-low reverse leakage preserves battery life and signal integrity in always-on circuits. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, halogen-free, RoHS-compliant, AEC-Q101 qualified. Cathode marked by single band on body.
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ60AHE3_A/H | RoHS-compliant but not AEC-Q101 qualified; same electrical specs and SMB package. | Limited to commercial/industrial use; unsuitable for automotive under-hood or safety-critical modules. | Select when AEC-Q101 is not required and cost optimization is prioritized over automotive qualification. |
| SMAJ60A-M3/A | Lower 400 W PPPM; SMA (DO-214AC) package with smaller footprint and higher RθJA (140 °C/W). | Acceptable for lower-energy transients (e.g., IEC 61000-4-2) but insufficient for ISO 7637-2 Pulse 5a. | Choose only if board space is constrained and surge threat level is limited to ESD-level events. |
Compared with SMBJ60AHM3_A/H, the HE3 variant lacks automotive qualification and the SMAJ60A-M3/A offers reduced surge capacity and thermal performance-making SMBJ60AHM3_A/H the optimal choice for AEC-Q101-mandated, high-energy transient protection in space-constrained SMB layouts.

FAQ
What is the clamping voltage of SMBJ60AHM3_A/H at its rated peak pulse current?
The SMBJ60AHM3_A/H has a maximum clamping voltage (VC) of 96.8 V at 6.2 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and ensures predictable overvoltage limiting during surge events. The SMBJ60AHM3_A/H maintains this clamping performance across its qualified operating temperature range of -55 °C to +150 °C.
Is SMBJ60AHM3_A/H suitable for automotive applications?
Yes, SMBJ60AHM3_A/H is AEC-Q101 qualified (denoted by the HM3 suffix), making it suitable for automotive applications including engine control units, body electronics, and ADAS sensors. Its halogen-free, RoHS-compliant construction, MSL Level 1 rating, and validated performance across temperature cycling and humidity stress confirm its readiness for under-hood and chassis-mounted use. The SMBJ60AHM3_A/H meets automotive-grade reliability requirements without derating.
How does the SMBJ60AHM3_A/H differ from the SMBJ60A-E3 variant?
The SMBJ60AHM3_A/H differs from SMBJ60A-E3 in three key aspects: it is halogen-free (vs. standard RoHS), AEC-Q101 qualified (vs. commercial grade), and supplied in 7" tape-and-reel (H code). Electrically, both share identical VWM, VBR, VC, and PPPM. The SMBJ60AHM3_A/H is intended for automotive and high-reliability industrial use, whereas SMBJ60A-E3 targets general commercial applications where qualification and material restrictions are not mandated.
What is the maximum reverse leakage current for SMBJ60AHM3_A/H at 60 V?
The SMBJ60AHM3_A/H exhibits a maximum reverse leakage current (ID) of 1.0 µA at its rated stand-off voltage of 60 V and ambient temperature of 25 °C. This ultra-low leakage is critical for battery-powered systems and precision analog circuits where standby current must be minimized. The SMBJ60AHM3_A/H maintains leakage below 5 µA even at elevated temperatures up to +125 °C, per characterization data in the Vishay datasheet 88392.
Can SMBJ60AHM3_A/H be used in bidirectional configurations?
No, SMBJ60AHM3_A/H is a unidirectional TVS diode, indicated by the "A" suffix and cathode band marking. Bidirectional operation requires the "CA" suffix (e.g., SMBJ60CA). Using SMBJ60AHM3_A/H in a bidirectional configuration would result in forward conduction during negative transients, potentially damaging the device or failing to suppress. For symmetric surge protection, select SMBJ60CA-HM3_A/H instead-the SMBJ60AHM3_A/H is strictly for DC rail or polarized signal line protection.
