Product details
Overview
SMBJ60CAHE3_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 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 across –55 °C to +150 °C junction temperature range - deployed in industrial sensor interface protection and automotive body control modules.
For engineers reviewing the SMBJ60CAHE3_B/H datasheet, SMBJ60CAHE3_B/H pinout, SMBJ60CAHE3_B/H application, or SMBJ60CAHE3_B/H equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), bidirectional clamping behavior, and real-world use context for ESD/surge protection 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 performance in both polarities, making it suitable for AC-coupled lines and floating signal paths without polarity concerns.
The device meets MSL Level 1 per J-STD-020 with 260 °C reflow peak, supports automated placement, and is qualified to AEC-Q101 for automotive under-hood applications. Its 600 W peak pulse rating applies to unidirectional and bidirectional configurations using the standardized 10/1000 µs waveform.
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 1 mA - Confirmed breakdown range ensures reliable turn-on during overvoltage events without premature conduction |
| VC @ IPPM | 96.8 V at 6.2 A - Clamped voltage seen by protected circuit during full 600 W transient; limits stress on downstream ICs |
| PPPM | 600 W - Peak pulse power handling per 10/1000 µs waveform; validates robustness against lightning-induced surges and inductive switching spikes |
| IPPM | 6.2 A - Corresponding peak pulse current at VC; used to size PCB trace width and verify system-level surge path integrity |
| TJ max. | +150 °C - Maximum junction temperature enabling operation in engine bay or industrial enclosures without derating |
| RθJA | 100 °C/W - Thermal resistance from junction to ambient on standard 0.2" × 0.2" copper pads; informs heatsinking requirements for repetitive surge duty |
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 |
|---|---|---|---|
| SMBJ60CA-E3/52 | Commercial-grade (non-AEC-Q101), same VWM/VC/PPPM, identical SMB package and pinout | Lacks automotive qualification; suitable for consumer/industrial designs where AEC-Q101 is not mandated | Select when cost sensitivity outweighs automotive qualification requirement and lifecycle assurance is not critical |
| SMCJ60CAHE3_A/H | Same electrical specs but in larger SMC (DO-214AB) package; higher thermal mass (RθJA = 40 °C/W), 1500 W PPPM | Used where higher surge repetition rate or longer pulse duration (e.g., 10/1000 µs at 0.1% duty cycle) demands lower thermal impedance | Choose when board space allows larger footprint and system-level testing requires >600 W single-pulse headroom |
Compared with SMBJ60CAHE3_B/H, SMBJ60CA-E3/52 offers identical protection performance without automotive qualification, while SMCJ60CAHE3_A/H trades compact SMB size for superior thermal handling and higher pulse power - enabling design flexibility across cost, qualification, and ruggedness tiers.

FAQ
What is the clamping voltage of SMBJ60CAHE3_B/H at its rated peak pulse current?
The SMBJ60CAHE3_B/H has a maximum clamping voltage (VC) of 96.8 V at its peak pulse current (IPPM) of 6.2 A, measured under the standard 10/1000 µs waveform. This value defines the upper voltage limit imposed on protected circuits during surge events and is confirmed in Vishay's datasheet revision 09-Jan-2024, Document Number 88392. The SMBJ60CAHE3_B/H maintains this clamping performance bidirectionally.
Is SMBJ60CAHE3_B/H qualified for automotive applications?
Yes, SMBJ60CAHE3_B/H is AEC-Q101 qualified, as indicated by the "HE3" suffix in its part number. This qualification covers stress tests including high-temperature operating life, temperature cycling, and ESD robustness, validating its use in automotive environments such as body control modules and lighting systems. The HE3 variant also meets RoHS and halogen-free requirements per Vishay's material categorization guidelines.
What does the "CA" suffix mean in SMBJ60CAHE3_B/H?
The "CA" suffix in SMBJ60CAHE3_B/H denotes a bidirectional configuration - meaning the device provides symmetrical transient suppression for both positive and negative voltage excursions. Unlike unidirectional variants (e.g., SMBJ60AHE3_B/H), the CA version has no cathode marking and exhibits identical VBR, VC, and IPPM characteristics in either polarity, making it ideal for AC signal lines and floating nodes.
What is the thermal resistance of SMBJ60CAHE3_B/H, and how does it affect layout?
The SMBJ60CAHE3_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. This value assumes standard SMB pad layout per Vishay's recommended footprint; reducing pad area increases RθJA, potentially limiting repetitive surge capability. For high-duty-cycle applications, designers should verify temperature rise using this RθJA and actual power dissipation.
How does SMBJ60CAHE3_B/H differ from SMBJ60AHE3_B/H?
SMBJ60CAHE3_B/H is bidirectional, while SMBJ60AHE3_B/H is unidirectional - resulting in different clamping behavior: the "CA" version protects both polarities symmetrically, whereas the "A" version only clamps positive transients (with cathode band indicating polarity). Electrically, SMBJ60CAHE3_B/H has identical VWM (60 V), VBR, and PPPM ratings but lacks forward voltage (VF) specification since it conducts in both directions. Layout and soldering are identical.
