Product details
Overview
SMBJ130CAHM3_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 at 1 mA), 209 A peak pulse current (IPPM) under 10/1000 µs waveform, and 600 W peak pulse power dissipation - deployed to protect MOSFETs, sensor interfaces, and industrial I/O circuits against ESD and inductive switching surges.
For engineers reviewing the SMBJ130CAHM3_B/H datasheet, SMBJ130CAHM3_B/H pinout, SMBJ130CAHM3_B/H application, or SMBJ130CAHM3_B/H equivalent, this device is evaluated for bidirectional surge protection in automotive-grade commercial designs where halogen-free, RoHS-compliant, AEC-Q101-qualified TVS performance and MSL Level 1 reflow compatibility are required.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, with identical electrical characteristics in forward and reverse directions. Its glass-passivated junction enables fast response time (<1 ns), low incremental surge resistance, and stable clamping behavior up to 150 °C junction temperature.
The device complies with ANSI/IEEE C62.35 for transient suppressors and meets UL 497B recognition (QVGQ2) for telecom and industrial protector classification. Its thermal resistance (RθJA = 100 °C/W) assumes mounting on 0.2" × 0.2" copper pads per terminal, supporting reliable operation under repetitive surge conditions at 0.01% duty cycle.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 130 V - maximum continuous reverse working voltage before clamping initiates; defines safe operating margin below breakdown. |
| VBR (min/max) | 144 V / 159 V at 1 mA - guaranteed breakdown onset range; ensures predictable turn-on during overvoltage events. |
| VC @ IPPM | 209 V - clamped voltage at 209 A peak pulse current (10/1000 µs); determines protected circuit's maximum transient exposure. |
| PPPM | 600 W - peak pulse power handling capability; supports robust suppression of high-energy transients without failure. |
| IPPM | 209 A - maximum non-repetitive surge current; sets absolute limit for single-event energy absorption. |
| TJ max. | 150 °C - maximum junction temperature; enables use in under-hood automotive and high-ambient industrial environments. |
| Package | SMB (DO-214AA) - standardized surface-mount outline with 5.59 mm length, 4.06 mm width, and 2.20 mm height; compatible with automated placement and J-STD-020 reflow (260 °C peak). |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, bidirectional configuration with no polarity marking - terminals are symmetrical and interchangeable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Bidirectional conduction path | Both terminals function identically; no cathode band marking; enables placement without orientation check in PCB layout. |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 µs) | Enables suppression of high-energy transients common in motor drives and relay-switched power rails without thermal runaway. |

| Halogen-free & RoHS-compliant | Meets environmental compliance mandates for industrial and consumer end-equipment sold in EU, China, and North America markets. |
| MSL Level 1 (260 °C peak) | Supports standard lead-free reflow profiles without moisture sensitivity concerns - eliminates baking requirement prior to assembly. |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (e.g., ESD >15 kV), improving protection margin for downstream ICs. |
Applications
| Industrial Motor Control | Automotive Sensor Interface |
|---|---|
Use Scenario: Protection of gate drivers and feedback sensing lines in variable-frequency drives exposed to inductive kickback from 3-phase motors. IC Role / Device Role / Timing Role: Bidirectional clamping element placed across DC bus or signal inputs to limit transient voltage to ≤209 V during 209 A surge events. Use Value: Prevents latch-up or oxide damage in isolated gate drivers (e.g., SiC MOSFET drivers) by maintaining voltage within safe SOA limits during 600 W surge pulses. |
Use Scenario: Surge protection on LIN/CAN physical layer signal lines and analog sensor outputs (e.g., pressure, temperature) in engine bay modules. IC Role / Device Role / Timing Role: Fast-response TVS suppressing ESD (IEC 61000-4-2) and load dump-induced spikes before they reach MCU ADC or transceiver inputs. Use Value: Ensures signal integrity and functional safety compliance (ISO 11898-2, ISO 16750-2) by clamping transients within 1 ns while sustaining AEC-Q101 qualification. |
| Telecom Power Supply Input | Consumer Appliance I/O Protection |
Use Scenario: Input-stage protection for AC/DC adapters and PoE-powered equipment subjected to lightning-induced surges on primary-side rectifier outputs. IC Role / Device Role / Timing Role: Primary-side TVS placed across bulk capacitor input to clamp line-to-line transients up to 600 W without derating at 85 °C ambient. Use Value: Extends system-level surge immunity to IEC 61000-4-5 Level 3 (2 kV/12 Ω) by limiting let-through voltage to 209 V during full 209 A test pulses. |
Use Scenario: Protection of USB, HDMI, and front-panel button inputs in smart home appliances against user-handling ESD and power rail coupling. IC Role / Device Role / Timing Role: Board-level TVS mounted directly at connector entry points to shunt >15 kV contact ESD away from SoC GPIOs and level shifters. Use Value: Achieves IEC 61000-4-2 Level 4 (8 kV contact / 15 kV air) compliance with minimal board space due to compact SMB footprint and bidirectional symmetry. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130CAHE3_B/H | Same electrical specs, but RoHS-compliant without halogen-free certification; uses matte tin plating per J-STD-002. | Approved for commercial-grade industrial and computing applications; not AEC-Q101 qualified. | Select when halogen-free content is not mandated and automotive qualification is unnecessary. |
| SMAJ130CAHM3 | Lower 400 W PPPM, 150 A IPPM, SMA (DO-214AC) package - smaller footprint (4.57 × 2.92 mm) but higher thermal resistance (RθJA = 140 °C/W). | Suitable for space-constrained consumer PCBs with lower surge exposure; not rated for automotive under-hood use. | Choose only if board area is critical and peak surge energy remains below 400 W. |
Compared with SMBJ130CAHM3_B/H, the HE3 variant trades halogen-free compliance for broader commercial acceptance, while the SMAJ130CAHM3 reduces surge capacity and thermal performance to fit tighter layouts - making SMBJ130CAHM3_B/H the optimal choice for AEC-Q101-requiring, high-energy industrial and automotive protection.

FAQ
What does the "CA" suffix indicate in SMBJ130CAHM3_B/H?
The "CA" suffix denotes a bidirectional configuration - meaning SMBJ130CAHM3_B/H provides symmetrical transient suppression in both polarities, with identical VBR, VC, and IPPM values regardless of voltage polarity. This eliminates the need for orientation-aware placement and simplifies design for AC-coupled or differential signal lines.
Is SMBJ130CAHM3_B/H suitable for automotive applications?
Yes - SMBJ130CAHM3_B/H carries the HM3 suffix, confirming it is halogen-free, RoHS-compliant, and AEC-Q101 qualified. It is validated for use in automotive subsystems such as body electronics, ADAS sensor interfaces, and infotainment power rails where sustained operation at 150 °C and resistance to mechanical stress are required.
What is the clamping voltage of SMBJ130CAHM3_B/H at its rated peak pulse current?
The clamping voltage (VC) of SMBJ130CAHM3_B/H is 209 V at its rated peak pulse current (IPPM) of 209 A, measured using the standardized 10/1000 µs double-exponential waveform. This value defines the maximum voltage imposed on protected circuitry during worst-case surge events.
How does the SMB package of SMBJ130CAHM3_B/H compare to SMA in thermal performance?
SMBJ130CAHM3_B/H in SMB (DO-214AA) package has RθJA = 100 °C/W (on 0.2" × 0.2" copper pads), significantly better than SMA's typical 140 °C/W. This allows SMBJ130CAHM3_B/H to sustain higher average power dissipation and operate reliably in higher ambient temperatures without derating.
Does SMBJ130CAHM3_B/H require orientation during PCB placement?
No - SMBJ130CAHM3_B/H is a bidirectional TVS with no polarity marking or cathode band. Its symmetrical construction means either terminal can serve as anode or cathode, enabling zero-orientation placement in automated SMT processes and eliminating assembly errors related to polarity misalignment.
