Product details
Overview
SMBJ60CAHM3_B/H 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 signal or power 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, and 600 W peak pulse power rating with 10/1000 µs waveform - used to protect MOSFETs, sensor interfaces, and industrial I/O lines against ESD and inductive switching surges.
For engineers reviewing the SMBJ60CAHM3_B/H datasheet, SMBJ60CAHM3_B/H pinout, SMBJ60CAHM3_B/H application, or SMBJ60CAHM3_B/H equivalent, key selection criteria include bidirectional clamping capability, low clamping ratio (VC/VWM = 1.61), AEC-Q101 qualification status, halogen-free RoHS compliance (HM3 suffix), and compatibility with automated SMT placement on PCBs with 5.0 mm × 5.0 mm copper pads.
Technical Context
This device operates as a voltage-clamping protector with symmetrical avalanche breakdown in both directions, enabling suppression of positive and negative transients without polarity sensitivity. Its glass-passivated junction ensures stable leakage performance (<1.0 µA at VWM) and fast response time (<1.0 ps), critical for protecting high-speed sensor signal lines and microcontroller I/O pins.
The SMBJ60CAHM3_B/H is rated for 150 °C maximum junction temperature and exhibits a typical thermal resistance of 100 °C/W (junction-to-ambient) when mounted on standard 0.2" × 0.2" copper pads. Its MSL Level 1 rating (per J-STD-020) and 260 °C lead-free reflow compatibility support robust manufacturing integration.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ60CAHE3_B/H | Same electrical specs and SMB package, but RoHS-compliant without halogen-free certification (E3 vs HM3). | Approved for commercial-grade industrial use; not qualified to AEC-Q101 or halogen-free standards. | Select when automotive qualification or halogen-free compliance is not required; lower cost alternative with identical clamping performance. |
| SMAJ60CAHM3_A/H | Lower peak pulse power (400 W vs 600 W), same VWM/VC, SMA (DO-214AC) package (smaller footprint, higher RθJA). | Limited to lower-energy transients; less thermal margin in high-temperature enclosures. | Choose for space-constrained designs where 400 W surge rating suffices and PCB area is critical; verify thermal derating above 70 °C ambient. |
Compared with SMBJ60CAHE3_B/H, the SMBJ60CAHM3_B/H adds halogen-free construction and AEC-Q101 qualification without sacrificing clamping performance; versus SMAJ60CAHM3_A/H, it delivers +50 % surge power headroom and superior thermal management in the larger SMB package.

FAQ
What is the clamping voltage of SMBJ60CAHM3_B/H at its rated peak pulse current?
The SMBJ60CAHM3_B/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 defines the upper voltage limit imposed on protected circuits during surge events. The SMBJ60CAHM3_B/H maintains this clamping performance across its full operating temperature range (-55 °C to +150 °C), making it suitable for under-hood automotive and industrial applications.
Is SMBJ60CAHM3_B/H suitable for automotive applications?
Yes, SMBJ60CAHM3_B/H is AEC-Q101 qualified and carries the HM3 suffix indicating halogen-free, RoHS-compliant, and automotive-grade construction. It meets stress testing requirements for temperature cycling, humidity, mechanical shock, and surge immunity relevant to engine control units, body control modules, and ADAS sensor interfaces. The SMBJ60CAHM3_B/H is explicitly listed in Vishay's AEC-Q101 qualified product matrix for transient voltage suppressors.
How does the bidirectional nature of SMBJ60CAHM3_B/H affect its circuit placement?
The SMBJ60CAHM3_B/H has no polarity marking and functions identically in both directions, allowing placement across any two nodes subject to bidirectional transients - such as differential signal lines (RS-485, CAN), AC-coupled inputs, or floating power rails. Unlike unidirectional TVS diodes, it eliminates the need for orientation verification during assembly and avoids failure modes caused by reverse installation. The SMBJ60CAHM3_B/H achieves symmetrical clamping with identical VBR and VC in either polarity.
What is the thermal resistance of SMBJ60CAHM3_B/H, and how does it impact layout?
The SMBJ60CAHM3_B/H has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. To achieve rated 600 W pulse power, PCB layout must provide adequate copper area and thermal vias; reducing pad size increases RθJA and requires derating per Figure 2 in the datasheet. The SMBJ60CAHM3_B/H also features RθJL = 20 °C/W (junction-to-lead), supporting efficient heat transfer through solder joints.
Does SMBJ60CAHM3_B/H meet lead-free reflow requirements?
Yes, SMBJ60CAHM3_B/H is rated for lead-free reflow with a maximum peak temperature of 260 °C and complies with MSL Level 1 per J-STD-020. Its matte tin-plated leads are solderable per J-STD-002 and JESD 22-B102, and it passes JESD 201 Class 2 whisker testing. The SMBJ60CAHM3_B/H requires no pre-baking and supports standard 260 °C reflow profiles used in high-volume SMT manufacturing.
