Product details
Overview
SMBJ160CAHE3_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 power and signal lines. It features 160 V standoff voltage (VWM), 259 V maximum clamping voltage (VC) at 2.3 A peak pulse current (IPPM), and 600 W peak pulse power (10/1000 µs waveform), targeting protection of MOSFETs, ICs, and sensor interfaces in industrial and telecom systems.
For engineers reviewing the SMBJ160CAHE3_B/H datasheet, SMBJ160CAHE3_B/H pinout, SMBJ160CAHE3_B/H application, or SMBJ160CAHE3_B/H equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), junction temperature range (–55 to +150 °C), and compliance with UL 497B surge protector classification.
Technical Context
This TVS diode operates as a voltage-clamping device across bidirectional signal or DC bus lines, responding within <1 ps to transient overvoltages induced by inductive switching or ESD events. Its glass-passivated junction ensures stable breakdown behavior and low leakage (<1.0 µA at VWM), while the SMB package supports automated placement and meets MSL level 1 reflow requirements (peak 260 °C).
The device delivers 600 W peak pulse power under standardized 10/1000 µs waveform conditions, with clamping voltage tightly specified at 259 V (max) at IPPM = 2.3 A. Its temperature coefficient of breakdown voltage is +0.108 %/°C, enabling predictable performance across –55 to +150 °C operating junction range.
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 |
|---|---|---|---|
| SMBJ160CA-M3 | Halogen-free, RoHS-compliant, commercial grade; lacks AEC-Q101 qualification and UL 497B recognition. | Restricted to non-automotive industrial and consumer applications where automotive reliability and telecom certification are not required. | Select when cost sensitivity outweighs automotive qualification needs and UL listing is unnecessary. |
| SMCJ160CAHE3_A/H | Same electrical specs but in larger SMC (DO-214AB) package; higher thermal mass (RθJA = 50 °C/W vs. 100 °C/W) and 1500 W PPPM. | Preferred for high-energy surge environments (e.g., outdoor telecom cabinets, solar inverters) where PCB space permits larger footprint. | Choose when higher surge endurance (>600 W) and lower thermal resistance are mandatory, accepting 2.5× larger board area. |
Compared with SMBJ160CAHE3_B/H, the M3 variant trades automotive qualification for lower cost in commercial systems, while the SMCJ160CAHE3_A/H offers superior thermal performance and surge rating at the expense of PCB real estate-enabling design flexibility across reliability, size, and energy-handling tiers.

FAQ
What is the maximum clamping voltage of SMBJ160CAHE3_B/H at its rated peak pulse current?
The SMBJ160CAHE3_B/H has a maximum clamping voltage (VC) of 259 V at its rated peak pulse current (IPPM) of 2.3 A 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 worst-case transient events. The SMBJ160CAHE3_B/H maintains this clamping performance across its full operating temperature range.
Is SMBJ160CAHE3_B/H suitable for automotive applications?
Yes, SMBJ160CAHE3_B/H is AEC-Q101 qualified and carries the HE3 suffix denoting RoHS-compliant, automotive-grade construction. It undergoes rigorous stress testing-including temperature cycling, high-temperature reverse bias, and ESD-to meet automotive electronic module requirements. The SMBJ160CAHE3_B/H is commonly deployed in body control units, lighting modules, and sensor interfaces where transient immunity and long-term reliability are mandated.
Does SMBJ160CAHE3_B/H have polarity markings on the package?
No, SMBJ160CAHE3_B/H is a bidirectional TVS diode and carries no polarity marking on the SMB (DO-214AA) package. Its symmetrical structure allows installation in either orientation across protected lines, eliminating placement errors during automated assembly. This contrasts with unidirectional variants (e.g., SMBJ160AHE3_B/H), which feature a cathode band for orientation-critical mounting.
What is the thermal resistance of SMBJ160CAHE3_B/H from junction to ambient?
The typical thermal resistance from junction to ambient (RθJA) for SMBJ160CAHE3_B/H is 100 °C/W when mounted on the recommended 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This value assumes standard JEDEC test conditions and informs thermal design margins-especially important in high-duty-cycle surge environments or elevated ambient temperatures. Derating curves in the datasheet guide power dissipation limits above 25 °C.
How does SMBJ160CAHE3_B/H differ from the unidirectional SMBJ160AHE3_B/H?
SMBJ160CAHE3_B/H is bidirectional with symmetrical clamping in both polarities and no cathode marking, whereas SMBJ160AHE3_B/H is unidirectional with a defined cathode band and conducts only in reverse bias. Electrically, SMBJ160CAHE3_B/H has identical VWM (160 V), VBR (178–197 V), and VC (259 V) ratings but supports AC-coupled or floating-line protection. The SMBJ160CAHE3_B/H is preferred for differential signal lines, transformer-coupled interfaces, and any application requiring polarity-agnostic surge suppression.
