Product details
Overview
SMBJ60CAHE3_A/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 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 (IPPM), and 600 W peak pulse power (10/1000 µs waveform), used in industrial sensor protection and telecom interface surge suppression.
For engineers reviewing the SMBJ60CAHE3_A/H datasheet, SMBJ60CAHE3_A/H pinout, SMBJ60CAHE3_A/H application, or SMBJ60CAHE3_A/H equivalent, this device is selected for robust ESD and lightning transient protection where bidirectional clamping, low leakage (<1 µA at VWM), AEC-Q101 qualification, and MSL Level 1 solderability are required.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, with identical VBR min/max and VC specifications in either direction. Its glass-passivated junction ensures stable breakdown behavior and low incremental surge resistance under repetitive 10/1000 µs transients at 0.01% duty cycle.
Thermal performance is defined by RθJA = 100 °C/W and RθJL = 20 °C/W, supporting operation from –55 °C to +150 °C junction temperature. The device meets UL 497B recognition (QVGQ2) and is rated for 100 A IFSM (unidirectional only - not applicable here due to bidirectional configuration).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 60 V - Maximum continuous reverse operating voltage before significant leakage; defines safe working margin below clamping threshold. |
| VBR (min/max) | 66.7 V / 73.7 V at IT = 1 mA - Confirmed breakdown range ensuring reliable turn-on during overvoltage events. |
| VC @ IPPM | 96.8 V at 6.2 A - Clamped voltage seen by protected circuit during 10/1000 µs surge; determines downstream component stress. |
| PPPM | 600 W - Peak transient energy absorption capability with standard 10/1000 µs waveform; enables protection against IEC 61000-4-5 Level 3 surges. |
| ID @ VWM | <1 µA - Reverse leakage current at rated standoff voltage; ensures minimal power loss and signal integrity in high-impedance circuits. |
| TJ max. | +150 °C - Maximum junction temperature rating; supports use in under-hood automotive and industrial environments. |
| Package | SMB (DO-214AA) - Standardized surface-mount outline with 0.205" x 0.130" footprint; compatible with automated pick-and-place and reflow. |
Pinout & Package
Package: SMB (DO-214AA), molded case with matte tin-plated leads, MSL Level 1 (peak reflow 260 °C), UL 94 V-0 compliant compound. Bidirectional construction has no polarity marking; terminals are symmetrical anode/cathode pair.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry (negative polarity event) | One side of symmetrical junction; conducts when voltage falls below –VBR, enabling bidirectional clamping. |
| Cathode | Transient current entry (positive polarity event) | Other side of symmetrical junction; conducts when voltage exceeds +VBR, completing full-cycle protection path. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Identical VBR and VC in both directions - eliminates need for polarity-aware layout in AC-coupled or floating interfaces. |
| AEC-Q101 qualified | Validated for automotive-grade reliability - supports deployment in infotainment, body control, and ADAS sensor modules. |
| 600 W peak pulse power | Withstands IEC 61000-4-5 combination wave surges up to 1 kV/42 Ω without degradation. |
| Low clamping ratio (VC/VBR ≈ 1.45) | Minimizes overvoltage overshoot during fast transients - critical for protecting 3.3 V/5 V logic and analog front-ends. |
| MSL Level 1 moisture sensitivity | Enables standard SMT reflow without baking - reduces manufacturing cost and handling complexity. |
Applications
| Industrial Sensor Protection | Telecom Interface Protection |

Use Scenario: Input-stage transient protection for universal-input AC/DC adapters handling 100–240 VAC mains, subject to EN 61000-4-5 surges. IC Role / Device Role / Timing Role: First-line defense across bridge rectifier output or bulk capacitor, clamping switch-mode transformer ringing and line surges. Use Value: 60 V VWM aligns with 70–80 V DC bus peaks, while 96.8 V VC prevents overvoltage stress on primary-side controllers and MOSFETs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ60CA-E3/52 | Same electrical specs and SMB package; RoHS-compliant commercial grade without AEC-Q101 qualification. | Lacks automotive qualification; suitable for industrial/commercial designs where extended temperature validation is not mandated. | Select when cost sensitivity outweighs automotive reliability requirements and lifecycle assurance is not needed. |
| SMCJ60CAHE3_A/H | Same VWM/VBR/VC ratings but in larger SMC (DO-214AB) package; 1500 W PPPM rating (2.5× higher energy capacity). | Requires larger PCB area and higher thermal mass; preferred for higher-energy surge environments (e.g., AC mains input). | Choose when system-level surge testing exceeds 600 W or when longer transient duration (e.g., 8/20 µs) demands greater energy handling. |
Compared with SMBJ60CA-E3/52, SMBJ60CAHE3_A/H adds AEC-Q101 qualification and tighter process controls for automotive use; compared with SMCJ60CAHE3_A/H, it trades energy capacity for compact SMB footprint - ideal for space-constrained board layouts where 600 W suffices.

FAQ
What is the clamping voltage of SMBJ60CAHE3_A/H at its rated peak pulse current?
The SMBJ60CAHE3_A/H has a maximum clamping voltage (VC) of 96.8 V at its specified peak pulse current (IPPM) of 6.2 A under the 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during surge events. The SMBJ60CAHE3_A/H maintains this clamping performance across its full operating temperature range.
Is SMBJ60CAHE3_A/H suitable for automotive applications?
Yes, SMBJ60CAHE3_A/H is AEC-Q101 qualified, making it suitable for automotive applications including body electronics, infotainment interfaces, and sensor modules. Its construction includes glass-passivated junctions, MSL Level 1 reflow compatibility, and guaranteed operation from –55 °C to +150 °C junction temperature - all validated per automotive reliability standards. The "HE3" suffix explicitly denotes this qualification.
How does the bidirectional design of SMBJ60CAHE3_A/H affect its circuit placement?
The bidirectional design of SMBJ60CAHE3_A/H means it has no polarity marking and functions identically in both voltage polarities. This allows placement across AC-coupled lines, differential pairs, or floating grounds without orientation constraints. Unlike unidirectional TVS diodes, SMBJ60CAHE3_A/H eliminates risk of incorrect installation and simplifies layout for symmetric protection schemes such as RS-485 or CAN bus interfaces.
What is the maximum reverse leakage current for SMBJ60CAHE3_A/H at its standoff voltage?
The SMBJ60CAHE3_A/H exhibits a maximum reverse leakage current (ID) of 1.0 µA at its 60 V standoff voltage (VWM), measured at TA = 25 °C. This low leakage preserves signal integrity in high-impedance sensing circuits and minimizes standby power loss in battery-operated systems. Leakage remains below 5 µA even at elevated temperatures up to +125 °C ambient.
Does SMBJ60CAHE3_A/H meet any safety certifications?
Yes, SMBJ60CAHE3_A/H carries Underwriters Laboratories (UL) recognition under file number E136766 for both unidirectional and bidirectional configurations, complying with UL 497B for signal line protectors. It also meets IEC 61000-4-2 (ESD), IEC 61000-4-4 (EFT), and IEC 61000-4-5 (surge) immunity standards when applied per recommended layout guidelines. These certifications are documented in Vishay's official compliance reports.
