Product details
Overview
SMBJ130CAHE3_B/I 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 130 V standoff voltage (VWM), 144–159 V breakdown range (VBR), 209 A peak pulse current (IPPM), 600 W peak pulse power (PPPM), and operates across –55 °C to +150 °C junction temperature - deployed in industrial sensor interface protection.
For engineers reviewing the SMBJ130CAHE3_B/I datasheet, SMBJ130CAHE3_B/I pinout, SMBJ130CAHE3_B/I application, or SMBJ130CAHE3_B/I equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification status, 10/1000 μs waveform surge handling, low clamping voltage (VC = 209 V), and compatibility with automated SMT assembly on PCBs requiring robust ESD and lightning surge immunity.
Technical Context
This bidirectional TVS diode uses a glass-passivated silicon junction to deliver symmetrical clamping in both polarities, enabling protection of AC-coupled or floating signal paths without polarity sensitivity. Its 20 Ω typical junction-to-lead thermal resistance (RθJL) and 100 °C/W junction-to-ambient rating support reliable transient energy dissipation under repetitive surge conditions when mounted on standard 5.0 mm × 5.0 mm copper pads.
The device meets MSL Level 1 per J-STD-020 with 260 °C reflow peak, and its AEC-Q101 qualification (indicated by HE3 suffix) confirms suitability for automotive electronics where reliability under thermal cycling and mechanical stress is critical - unlike non-qualified variants such as E3 or M3.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 130 V - maximum continuous reverse operating voltage before clamping initiates; defines safe working margin for 120 VAC-derived rails or 110 VDC bus systems. |
| VBR min/max | 144 V / 159 V at 1 mA test current - guaranteed breakdown threshold ensures predictable turn-on during overvoltage events. |
| VC @ IPPM | 209 V - clamped voltage at 209 A peak pulse current (10/1000 μs); determines maximum stress imposed on downstream ICs during surge. |
| PPPM | 600 W - peak pulse power handling capacity with 10/1000 μs waveform; supports IEC 61000-4-5 Level 3 (1 kV/2 kV) surge immunity testing. |
| ID @ VWM | 1.0 μA - ultra-low reverse leakage at rated standoff voltage, minimizing standby power loss in battery-backed or low-power sensor nodes. |
| TJ max | +150 °C - extended junction temperature rating enables use in under-hood automotive modules or high-ambient industrial enclosures. |
| Package | SMB (DO-214AA) - standardized surface-mount outline with 5.59 mm × 4.06 mm footprint and 2.20 mm height; compatible with JEDEC MS-012AC. |
Pinout & Package
Package: SMB (DO-214AA), molded plastic case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102; no polarity marking for bidirectional configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias; symmetrical with cathode in bidirectional operation | Enables clamping conduction regardless of voltage polarity - eliminates need for orientation-aware placement on PCB. |
| Cathode | Current exit terminal in forward bias; electrically identical to anode in bidirectional mode | Provides matched dynamic impedance in both directions, ensuring consistent clamping behavior on differential or AC signal lines. |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 μs) | Supports repeated surge events up to 0.01% duty cycle without degradation - suitable for industrial motor drive control feedback loops. |
| AEC-Q101 qualified (HE3 suffix) | Validated for automotive-grade reliability including temperature cycling, humidity bias, and mechanical shock - required for ADAS camera power rail protection. |
| Low clamping ratio (VC/VBR ≈ 1.37) | Minimizes overvoltage overshoot during fast transients, protecting sensitive analog front-ends like Hall-effect sensors or CAN transceivers. |
| MSL Level 1 moisture sensitivity | Allows unlimited floor life and single-reflow processing at 260 °C peak - simplifies manufacturing for high-volume automotive ECUs. |
| Glass-passivated junction | Enhances long-term stability and reduces parameter drift under thermal stress - critical for field-deployed telecom infrastructure equipment. |
Applications
| Industrial Sensor Interface Protection | Automotive Power Rail Clamping |

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-E3/52 | Commercial-grade RoHS-compliant variant; lacks AEC-Q101 qualification and HE3 suffix; same electrical specs and SMB package. | Approved for industrial and consumer applications but not automotive production; lower qualification cost and broader distributor stock. | Select when AEC-Q101 is not mandated and lifecycle assurance beyond 10 years is not required. |
| SMAJ130CAHE3_A/H | Same VWM/VBR/VC ratings but in smaller SMA (DO-214AC) package; 400 W PPPM (vs. 600 W); RθJA = 140 °C/W (vs. 100 °C/W). | Used where board space is constrained but surge energy is lower; unsuitable for high-repetition or high-ambient environments. | Choose only if layout area is limited and peak surge current remains below 150 A per IEC 61000-4-5 Level 2. |
Compared with SMBJ130CAHE3_B/I, the E3/52 alternative offers identical clamping performance at lower cost but no automotive qualification, while the SMAJ130CAHE3_A/H trades 33 % lower power handling and higher thermal resistance for 30 % smaller footprint - making SMBJ130CAHE3_B/I optimal for thermally demanding, safety-critical deployments.

FAQ
What does the "CA" suffix indicate in SMBJ130CAHE3_B/I?
The "CA" suffix denotes a bidirectional configuration, meaning SMBJ130CAHE3_B/I provides symmetrical clamping in both voltage polarities - essential for protecting AC-coupled circuits, differential buses like RS-485, or floating sensor inputs where polarity cannot be assumed. This differs from unidirectional "A" variants that require correct cathode orientation.
Is SMBJ130CAHE3_B/I suitable for automotive applications?
Yes - the "HE3" suffix confirms SMBJ130CAHE3_B/I is AEC-Q101 qualified, having passed stress tests for temperature cycling, humidity bias, and mechanical shock required for automotive electronics. It is specified for under-hood and cabin modules where sustained reliability under thermal and vibration stress is mandatory.
What is the clamping voltage VC of SMBJ130CAHE3_B/I and why does it matter?
The clamping voltage VC of SMBJ130CAHE3_B/I is 209 V at 209 A (10/1000 μs waveform). This value defines the maximum voltage seen by downstream circuitry during a surge event - directly determining whether connected ICs (e.g., microcontrollers or transceivers) remain within their absolute maximum ratings and avoid permanent damage.
How does SMBJ130CAHE3_B/I differ from SMBJ130AHE3_B/I?
SMBJ130CAHE3_B/I is bidirectional with symmetrical VBR and clamping, while SMBJ130AHE3_B/I is unidirectional and requires correct cathode orientation. The "CA" version supports AC or floating lines; the "A" version is used on DC rails with defined polarity. Both share identical VWM (130 V), PPPM (600 W), and AEC-Q101 qualification.
What PCB pad layout is recommended for SMBJ130CAHE3_B/I?
Vishay specifies mounting SMBJ130CAHE3_B/I on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal to achieve rated thermal performance and 600 W pulse power handling. Smaller pads reduce heat dissipation, derating IPPM and increasing risk of thermal runaway during repetitive surges - especially critical in automotive or industrial designs.
