Product details
Overview
SMBJ60AHE3_B/I 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 ESD, lightning-induced surges, and inductive switching transients. It features a 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, and 600 W peak pulse power rating with 10/1000 µs waveform.
For engineers reviewing the SMBJ60AHE3_B/I datasheet, SMBJ60AHE3_B/I pinout, SMBJ60AHE3_B/I application, or SMBJ60AHE3_B/I equivalent, key selection criteria include clamping performance under 6.2 A surge, unidirectional polarity for DC rail protection, AEC-Q101 qualification status, and compatibility with automated SMT assembly on 0.2" × 0.2" copper pads.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (<1 µA leakage at 60 V), but triggers into low-impedance conduction when transient voltage exceeds its breakdown threshold. Its glass-passivated junction ensures stable VBR tolerance (±5%) and fast response time (<1 ns).
Thermal design relies on RθJA = 100 °C/W (typ.) and RθJL = 20 °C/W (typ.), requiring PCB copper pad thermal management per recommended 0.2" × 0.2" layout. The device is rated for -55 °C to +150 °C operating junction temperature and meets MSL Level 1 per J-STD-020.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 60 V - Maximum continuous reverse working voltage before clamping begins; sets upper limit for protected DC rail. |
| VBR (min/max) | 66.7 V / 73.7 V at IT = 1 mA - Confirmed breakdown range defining turn-on threshold with ±5% tolerance. |
| VC @ IPPM | 96.8 V at 6.2 A - Clamped voltage during 600 W surge; determines maximum stress on downstream ICs. |
| PPPM | 600 W - Peak pulse power handling with 10/1000 µs waveform; defines transient energy absorption capability. |
| IPPM | 6.2 A - Peak pulse current corresponding to 600 W clamping; used for PCB trace and fuse sizing. |
| TJ max | +150 °C - Maximum junction temperature; supports operation in under-hood automotive and industrial environments. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing. |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ60AHM3_B/I | Halogen-free version of same electrical specs; identical VWM, VBR, VC, PPPM. | Required where halogen-free compliance is mandated (e.g., EU public transport, medical devices). | Select SMBJ60AHM3_B/I only if halogen-free material declaration is contractually required. |
| SMAJ60AHE3/A | Lower power rating (400 W), smaller SMA package (DO-214AC), higher RθJA (140 °C/W), same VWM/VBR. | Suitable for space-constrained consumer electronics with lower surge exposure (IEC 61000-4-2 only). | Choose SMAJ60AHE3/A only when board area is critical and 400 W surge immunity suffices. |
Compared with SMBJ60AHE3_B/I, SMBJ60AHM3_B/I offers identical protection performance with halogen-free construction, while SMAJ60AHE3/A trades 33% lower surge power and higher thermal resistance for 30% smaller footprint-neither is pin-compatible due to different package outlines (SMB vs. SMA).

FAQ
What is the maximum clamping voltage of SMBJ60AHE3_B/I at its rated peak pulse current?
The SMBJ60AHE3_B/I has a maximum clamping voltage (VC) of 96.8 V at its specified peak pulse current (IPPM) of 6.2 A, measured with a 10/1000 µs waveform. This value defines the upper voltage limit imposed on protected circuitry during a 600 W transient event and is confirmed in the Vishay datasheet revision 09-Jan-2024, page 2.
Is SMBJ60AHE3_B/I qualified for automotive applications?
Yes, SMBJ60AHE3_B/I is AEC-Q101 qualified, as indicated by the "HE3" suffix per Vishay's ordering nomenclature. This qualification covers stress tests including temperature cycling, high-temperature reverse bias, and ESD, making SMBJ60AHE3_B/I suitable for automotive powertrain, body electronics, and ADAS modules without additional component-level validation.
What does the "B/I" suffix in SMBJ60AHE3_B/I signify?
The "B/I" suffix in SMBJ60AHE3_B/I denotes packaging configuration: "B" indicates the base part is AEC-Q101 qualified (HE3), and "I" specifies 13-inch tape-and-reel delivery with 3200 units per reel. This matches Vishay's ordering information table on page 3 of document 88392, confirming SMBJ60AHE3_B/I is supplied in bulk industrial packaging.
How does SMBJ60AHE3_B/I differ from bidirectional variants like SMBJ60CA?
SMBJ60AHE3_B/I is unidirectional, with polarity marked by a cathode band and intended for DC line protection; SMBJ60CA is bidirectional, lacks polarity marking, and protects AC or dual-polarity signals. Their VBR and VC values differ: SMBJ60CA has symmetric breakdown in both directions, while SMBJ60AHE3_B/I conducts only in reverse bias-making them functionally non-interchangeable without circuit redesign.
What is the thermal resistance from junction to ambient for SMBJ60AHE3_B/I?
The typical thermal resistance from junction to ambient (RθJA) for SMBJ60AHE3_B/I is 100 °C/W, measured on the standard 0.2" × 0.2" copper pad layout per JEDEC standards. This value assumes no additional heatsinking and must be derated above 25 °C ambient, as shown in Figure 2 of the Vishay datasheet (document 88392, page 4).
