Product details
Overview
SMBJ130CAHE3_A/I from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 130 V standoff voltage (VWM), 144–159 V breakdown (VBR), and 600 W peak pulse power (10/1000 µs). It clamps transients to ≤209 V at 2.9 A peak surge current and operates from –55 °C to +150 °C - deployed for ESD and lightning surge protection on industrial sensor signal lines and DC power rails.
For engineers reviewing the SMBJ130CAHE3_A/I datasheet, SMBJ130CAHE3_A/I pinout, SMBJ130CAHE3_A/I application, or SMBJ130CAHE3_A/I equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification status, 209 V maximum clamping voltage at rated IPPM, low thermal resistance (RθJL = 20 °C/W), and compatibility with automated SMT placement on 0.2" × 0.2" copper pads.
Technical Context
This device functions as a voltage-clamping protector using an avalanche junction structure, responding in <1 ps to transient overvoltages. Its bidirectional symmetry enables suppression of both positive and negative polarity surges without polarity-sensitive layout constraints.
Designed for unclamped inductive switching events and lightning-induced surges, it delivers stable clamping performance across –55 °C to +150 °C with ±0.108 %/°C VBR temperature coefficient and meets MSL Level 1 reflow requirements (peak 260 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 130 V - maximum continuous reverse operating voltage before clamping initiates |
| VBR min/max | 144 V / 159 V at 1 mA - guaranteed avalanche conduction onset range under standardized test conditions |
| VC @ IPPM | 209 V at 2.9 A - maximum clamped voltage during 10/1000 µs surge, defining worst-case downstream voltage stress |
| PPPM | 600 W - peak transient power handling capacity per single 10/1000 µs waveform, derated above 25 °C |
| RθJL | 20 °C/W - low junction-to-lead thermal resistance enabling effective heat transfer to PCB copper pads |
| TJ max | +150 °C - maximum allowable junction temperature, supporting operation in high-ambient industrial environments |
| MSL Level | Level 1 (J-STD-020) - supports standard Pb-free reflow without dry-pack or bake requirements |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, bidirectional configuration with no polarity marking; matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (Anode) | Transient current return path (bidirectional) | Both terminals function identically - surge current flows symmetrically regardless of polarity; no cathode band marking |
| Anode (Cathode) | Transient current entry point (bidirectional) | Identical electrical behavior to opposite terminal; enables layout flexibility without orientation constraints |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130CA-M3 | Same electrical specs and SMB package; halogen-free, RoHS-compliant, but not AEC-Q101 qualified | Lacks automotive qualification - suitable for commercial/industrial use where AEC-Q101 is not mandated | Select when cost sensitivity outweighs automotive reliability requirements and halogen-free compliance is prioritized |
| SMCJ130CAHE3_A/I | Same VWM/VBR/VC ratings but in larger SMC (DO-214AB) package; higher 1500 W PPPM rating | Requires larger PCB footprint and higher thermal mass; better suited for higher-energy surge environments | Choose when system-level surge testing exceeds 600 W or when board layout allows SMC footprint and enhanced thermal margin is needed |
Compared with SMBJ130CAHE3_A/I, SMBJ130CA-M3 offers identical clamping performance without automotive qualification, while SMCJ130CAHE3_A/I provides 2.5× higher pulse power in a larger package - selection depends on required reliability grade and surge energy budget.

FAQ
What is the clamping voltage of SMBJ130CAHE3_A/I at its rated peak pulse current?
The SMBJ130CAHE3_A/I has a maximum clamping voltage (VC) of 209 V when subjected to its rated peak pulse current (IPPM) of 2.9 A under the standard 10/1000 µs waveform. This value defines the upper voltage limit imposed on protected circuitry during surge events and is measured with the device mounted on 0.2" × 0.2" copper pads per JEDEC guidelines. The SMBJ130CAHE3_A/I maintains this clamping performance across its full operating temperature range.
Is SMBJ130CAHE3_A/I suitable for automotive applications?
Yes, SMBJ130CAHE3_A/I is AEC-Q101 qualified, confirming its suitability for automotive applications including body control modules, infotainment power supplies, and ADAS sensor interfaces. The "HE3" suffix denotes RoHS-compliant construction with AEC-Q101 qualification, and the device undergoes stress testing for temperature cycling, highly accelerated life testing (HALT), and ESD per automotive reliability standards. Its –55 °C to +150 °C operating range further supports under-hood deployment.
What does the "CA" suffix indicate in SMBJ130CAHE3_A/I?
The "CA" suffix in SMBJ130CAHE3_A/I designates a bidirectional Transient Voltage Suppressor - meaning the device provides symmetrical clamping for both positive and negative polarity transients without requiring polarity-aware PCB layout. Unlike unidirectional variants (e.g., SMBJ130A), the CA version has no cathode marking and exhibits identical VBR, VC, and IPPM characteristics in either direction, making it ideal for AC-coupled lines, differential buses, and floating power domains.
What is the thermal resistance from junction to lead (RθJL) for SMBJ130CAHE3_A/I?
The SMBJ130CAHE3_A/I has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W, as specified in Vishay's datasheet. This low value enables efficient heat transfer from the silicon die to the PCB copper pads through the SMB (DO-214AA) package leads, supporting reliable operation under repetitive surge conditions without external heatsinking. It is measured under standard mounting conditions with 0.2" × 0.2" copper pads per terminal.
Does SMBJ130CAHE3_A/I require special handling for moisture sensitivity?
No, SMBJ130CAHE3_A/I is rated MSL Level 1 per J-STD-020, meaning it has unlimited floor life and can be processed on standard Pb-free reflow lines without baking or dry-pack requirements. This eliminates moisture-related assembly risks such as popcorning and reduces manufacturing complexity - a key advantage for high-volume industrial and automotive production where process robustness is critical. The device withstands peak reflow temperatures up to 260 °C.
