Product details
Overview
SMBJ60CAHM3/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 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), 96.8 V maximum clamping voltage (VC) at 6.2 A, and operates from −55 °C to +150 °C - deployed in industrial sensor interface protection and automotive ECUs.
For engineers reviewing the SMBJ60CAHM3/H datasheet, SMBJ60CAHM3/H pinout, SMBJ60CAHM3/H application, or SMBJ60CAHM3/H equivalent, this page delivers verified electrical specs, thermal behavior, bidirectional surge response, AEC-Q101 qualification status, and real-world design context for ESD/lightning transient suppression in 12 V/24 V systems.
Technical Context
This bidirectional TVS diode uses a glass-passivated silicon junction to achieve sub-nanosecond response time and low incremental surge resistance. Its symmetrical I-V characteristic enables identical clamping in both polarities, with no polarity marking required on the SMB package body.
The device meets MSL Level 1 per J-STD-020 (reflow peak 260 °C), supports 0.01 % duty cycle repetitive surge events, and is halogen-free and RoHS-compliant under HM3 suffix designation. Thermal resistance is 100 °C/W (junction-to-ambient) and 20 °C/W (junction-to-lead) on standard 5.0 mm × 5.0 mm copper pads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 60 V - Maximum continuous reverse operating voltage before conduction begins; defines safe working range for 12 V/24 V bus protection. |
| VBR (min/max) | 66.7 V / 73.7 V at 1 mA - Confirmed breakdown threshold ensures reliable triggering above normal transients but below system damage thresholds. |
| VC @ IPPM | 96.8 V at 6.2 A - Clamped voltage during 10/1000 µs surge limits stress on downstream ICs like CAN transceivers or microcontrollers. |
| PPPM | 600 W - Peak pulse power handling capability validates robustness against ISO 7637-2 Pulse 1/2a/3a and IEC 61000-4-5 surges. |
| IPPM | 6.2 A - Peak surge current rating directly maps to standardized test waveforms and PCB trace current-carrying capacity. |
| TJ max. | +150 °C - Junction temperature limit supports operation in under-hood automotive environments and sealed industrial enclosures. |
| Package | SMB (DO-214AA) - Surface-mount footprint (5.21 mm × 4.57 mm × 2.20 mm) compatible with automated placement and reflow soldering. |
Pinout & Package

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/H | Same electrical specs and SMB package, but RoHS-compliant commercial grade (non-halogen-free, non-AEC-Q101). | Lacks AEC-Q101 qualification and halogen-free certification - suitable for industrial/commercial, not automotive. | Select when AEC-Q101 and halogen-free compliance are not required; lower cost alternative for non-automotive designs. |
| SMAJ60CAHM3 | Lower peak pulse power (400 W vs. 600 W); same VWM/VBR/VC, but in smaller SMA (DO-214AC) package. | Reduced surge margin; limited to lighter-duty transients (e.g., IEC 61000-4-2 ESD only, not full IEC 61000-4-5). | Choose for space-constrained layouts where 400 W surge rating suffices and board area is critical. |
Compared with SMBJ60CAHE3/H, the SMBJ60CAHM3/H adds halogen-free construction and AEC-Q101 qualification without changing electrical performance - essential for automotive Tier-1 suppliers. Versus SMAJ60CAHM3, it delivers 50 % higher surge power in a slightly larger footprint, enabling robust protection in harsh environments.

FAQ
What is the clamping voltage of SMBJ60CAHM3/H at its rated peak pulse current?
The SMBJ60CAHM3/H has a maximum clamping voltage (VC) of 96.8 V at its rated peak pulse current (IPPM) of 6.2 A under a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 standards and ensures downstream components see voltage limited well below destructive thresholds. The SMBJ60CAHM3/H maintains this clamping performance across its full operating temperature range.
Is SMBJ60CAHM3/H suitable for automotive applications?
Yes, SMBJ60CAHM3/H is AEC-Q101 qualified and carries the HM3 suffix indicating halogen-free, RoHS-compliant, and automotive-grade construction. It is explicitly listed in Vishay's AEC-Q101 qualified product table and used in engine control units, body electronics, and ADAS sensor interfaces where reliability under thermal cycling and surge stress is mandatory. The SMBJ60CAHM3/H meets all required lifetime and failure mode criteria.
How does SMBJ60CAHM3/H differ from unidirectional SMBJ60A variants?
The SMBJ60CAHM3/H is bidirectional, meaning it clamps transients of either polarity symmetrically - no cathode band marking, and identical VBR and VC in both directions. In contrast, unidirectional SMBJ60A has a defined cathode (band-marked), conducts forward current only in one direction, and is unsuitable for AC or floating-line protection. The "CA" suffix in SMBJ60CAHM3/H explicitly denotes bidirectional functionality.
What is the thermal resistance of SMBJ60CAHM3/H, and how does it affect layout?
SMBJ60CAHM3/H has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W and junction-to-lead (RθJL) of 20 °C/W when mounted on 5.0 mm × 5.0 mm copper pads per terminal. This means PCB layout must allocate sufficient copper area to avoid exceeding +150 °C junction temperature during repetitive surges. Reducing pad size increases RθJA and risks thermal runaway - the SMBJ60CAHM3/H datasheet specifies minimum pad dimensions for rated performance.
Does SMBJ60CAHM3/H require orientation during PCB assembly?
No, SMBJ60CAHM3/H does not require orientation during PCB assembly because it is a bidirectional TVS diode with symmetrical terminals. Unlike unidirectional variants (e.g., SMBJ60A), there is no cathode band marking, and both terminals function identically regardless of voltage polarity. This eliminates orientation verification steps in SMT lines and reduces assembly error risk - a key advantage of the SMBJ60CAHM3/H in high-volume production.
