Product details
Overview
SMBJ130CAHE3_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 a 130 V standoff voltage (VWM), 144–159 V breakdown range (VBR), 209 A peak pulse current (IPPM), 600 W peak pulse power (PPPM), and 2.9 μA max reverse leakage at VWM - deployed in industrial sensor interfaces and telecom line protection.
For engineers reviewing the SMBJ130CAHE3_B/H datasheet, SMBJ130CAHE3_B/H pinout, SMBJ130CAHE3_B/H application, or SMBJ130CAHE3_B/H equivalent, this page delivers verified electrical specs, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), clamping behavior under 10/1000 μs surge, and real-world use cases in bidirectional overvoltage protection circuits.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, with identical VBR min/max (144 V / 159 V), VC = 209 V at IPPM, and low incremental surge resistance enabling fast clamping response (<1 ns). Its glass-passivated junction ensures stable breakdown characteristics and long-term reliability under repetitive transient stress.
The device is rated for TJ = -55 °C to +150 °C, meets MSL Level 1 per J-STD-020 (260 °C peak reflow), and is qualified to AEC-Q101 - confirming suitability for automotive electronics where transient immunity and solder-joint integrity are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 130 V - maximum continuous reverse operating voltage before clamping begins |
| VBR (min/max) | 144 V / 159 V - guaranteed breakdown voltage range at 1 mA test current, defining turn-on threshold |
| VC @ IPPM | 209 V - clamped voltage during 209 A 10/1000 μs surge, limiting downstream IC stress |
| PPPM | 600 W - peak transient power handling capability under standardized 10/1000 μs waveform |
| ID @ VWM | 2.9 μA - ultra-low reverse leakage at standoff voltage, minimizing standby power loss |
| RθJA | 100 °C/W - thermal resistance junction-to-ambient on standard 0.2" × 0.2" copper pads |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD |
Pinout & Package

Applications
| Industrial Sensor Interface | Telecom Line Protection |
|---|---|
|
Use Scenario: Protecting RS-485 transceivers and analog sensor outputs from ESD and lightning-induced surges on factory floor wiring. IC Role / Device Role / Timing Role: Bidirectional voltage clamp placed across differential pair or supply rail to limit transient excursions. Use Value: Clamps 209 V at 209 A, preventing damage to ±10 V tolerant transceivers while maintaining signal integrity below 130 V normal operation. |
Use Scenario: Safeguarding Ethernet PHY front-end circuitry against induced surges on twisted-pair data lines in outdoor telecom cabinets. IC Role / Device Role / Timing Role: Primary-level TVS mounted at connector entry point to shunt common-mode transients before reaching magnetics or PHY IC. Use Value: Symmetrical 144–159 V breakdown ensures equal protection for both line polarities, eliminating need for dual unidirectional devices. |
| Automotive Body Control Module | Power Supply Input Stage |
|
Use Scenario: Suppressing load-dump and jump-start transients on 12 V CAN/LIN bus power rails in BCMs. IC Role / Device Role / Timing Role: Secondary-stage TVS parallel to bulk input capacitor, activated after primary fuse or polyfuse limits energy. Use Value: AEC-Q101 qualification guarantees operation from -40 °C to +125 °C ambient, with 209 V clamping limiting stress on downstream DC/DC controllers. |
Use Scenario: Protecting AC/DC adapter secondary-side outputs and DC-DC converter inputs from cross-talk and back-EMF spikes. IC Role / Device Role / Timing Role: Clamp placed between output rail and ground to absorb short-duration overshoots during regulation transitions. Use Value: 2.9 μA leakage at 130 V minimizes quiescent current impact on low-power standby modes, while 600 W rating handles worst-case surge events. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130CA-E3/52 | Commercial-grade (non-AEC-Q101), same VWM/VBR/VC/PPPM, identical SMB package | Lacks automotive qualification; suitable for industrial/commercial designs without AEC requirements | Select when AEC-Q101 is not mandated and cost optimization is prioritized |
| SAC130CA | Same 130 V VWM, but SOD-123FL package (smaller footprint, lower IPPM = 170 A, PPPM = 400 W) | Lower surge capacity; limited to lower-energy transients in space-constrained layouts | Choose only if board area is critical and surge threat level is reduced per IEC 61000-4-5 Level 3 |
Compared with SMBJ130CAHE3_B/H, the E3/52 variant offers identical electrical performance without automotive qualification, while SAC130CA trades surge robustness for miniaturization - making SMBJ130CAHE3_B/H the optimal choice for AEC-compliant, high-energy transient environments.

FAQ
What is the clamping voltage of SMBJ130CAHE3_B/H at its rated peak pulse current?
The SMBJ130CAHE3_B/H clamps to a maximum of 209 V when subjected to its rated 209 A peak pulse current (IPPM) 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 circuitry during surge events - critical for ensuring downstream ICs remain within absolute maximum ratings.
Is SMBJ130CAHE3_B/H suitable for automotive applications?
Yes, SMBJ130CAHE3_B/H is AEC-Q101 qualified, confirming compliance with stress tests including high-temperature reverse bias, temperature cycling, and ESD. Its -55 °C to +150 °C operating junction temperature range and MSL Level 1 reflow compatibility make it appropriate for under-hood and cabin automotive modules such as body control units and infotainment power supplies.
How does the bidirectional design of SMBJ130CAHE3_B/H affect its PCB layout?
The SMBJ130CAHE3_B/H has no polarity marking and symmetrical terminals, simplifying PCB layout by eliminating orientation constraints. It can be placed across any two nodes requiring bidirectional overvoltage protection - such as differential signal pairs or floating power rails - without concern for anode/cathode alignment, reducing assembly errors and enabling automated placement on either side of a board.
What is the thermal resistance of SMBJ130CAHE3_B/H, and how does it impact power dissipation?
SMBJ130CAHE3_B/H has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" copper pads. This means a 5.0 W steady-state power dissipation (PD) raises the junction temperature by 500 °C above ambient - but since PD is specified at TA = 50 °C and derates above that, actual safe continuous power depends on board layout and airflow. The 600 W PPPM rating applies only to short-duration pulses, not DC loading.
Does SMBJ130CAHE3_B/H meet RoHS and halogen-free requirements?
Yes, SMBJ130CAHE3_B/H carries the "HE3" suffix, indicating it is RoHS-compliant and AEC-Q101 qualified. Per Vishay documentation, HE3 parts use matte tin-plated leads and molding compounds meeting UL 94 V-0, with no restricted substances per EU RoHS Directive 2011/65/EU. Halogen-free status is confirmed for HM3 variants, but HE3 is RoHS-compliant without explicit halogen-free certification.
