Product details
Overview
SMBJ130CA-E3/5B 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 signal or power lines. It features a 130 V standoff voltage (VWM), 144–159 V breakdown range (VBR at 1 mA), 209 A peak pulse current (IPPM) with 10/1000 µs waveform, and 600 W peak pulse power-used to protect MOSFETs, sensor interfaces, and industrial I/O circuits against ESD and inductive switching surges.
For engineers reviewing the SMBJ130CA-E3/5B datasheet, SMBJ130CA-E3/5B pinout, SMBJ130CA-E3/5B application, or SMBJ130CA-E3/5B equivalent, key selection criteria include bidirectional clamping capability, 130 V working voltage compatibility, SMB package thermal performance (RθJA = 100 °C/W), and AEC-Q101 qualification eligibility via HE3/HM3 variants.
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 voltage (VC = 209 V at IPPM), critical for protecting sensitive analog inputs and digital communication lines from repetitive transients.
The device complies with ANSI/IEEE C62.35 standards for transient suppressors and meets J-STD-020 MSL Level 1 moisture sensitivity. Its matte tin-plated leads are solderable per J-STD-002 and JESD 22-B102, and it supports automated placement due to low-profile SMB packaging.

Applications
| Industrial Motor Control I/O | Automotive Sensor Signal Lines |
|---|---|
Use Scenario: Protecting PLC digital input modules from inductive kickback during solenoid or relay switching. IC Role / Device Role / Timing Role: Bidirectional clamping element placed across input terminals to shunt transient energy to ground.

Use Value: Limits ESD-induced voltage to <209 V within nanoseconds, preventing MCU reset or GPIO damage during 8 kV contact discharge. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130A-E3/5B | Unidirectional variant; cathode-marked; VF ≤ 3.5 V at 50 A forward conduction | Requires polarity-aware PCB layout; unsuitable for AC-coupled or floating signal lines | Select only if system ground reference is fixed and reverse conduction must be blocked |
| SMCJ130CA | Larger SMC (DO-214AB) package; higher PPPM = 1500 W; RθJA = 40 °C/W | Occupies more board area; better thermal dissipation for high-duty-cycle surges | Choose when surge repetition rate exceeds 0.01 % duty cycle or ambient exceeds 85 °C |
Compared with SMBJ130CA-E3/5B, the unidirectional SMBJ130A-E3/5B requires strict polarity alignment and blocks reverse conduction, while the SMCJ130CA offers higher surge capacity at the cost of footprint and assembly compatibility-making SMBJ130CA-E3/5B optimal for space-constrained, bidirectional protection in commercial and industrial designs.

FAQ
What is the clamping voltage of SMBJ130CA-E3/5B at its rated peak pulse current?
The SMBJ130CA-E3/5B has a maximum clamping voltage (VC) of 209 V when subjected to its rated peak pulse current (IPPM) of 209 A using the standardized 10/1000 µs waveform. This value is measured per Figure 1 in Vishay document 88392 and defines the upper voltage limit imposed on protected circuitry during transient events. The SMBJ130CA-E3/5B maintains this clamping performance across its full operating temperature range of –55 °C to +150 °C.
Is SMBJ130CA-E3/5B suitable for automotive applications?
SMBJ130CA-E3/5B itself is a commercial-grade part (E3 suffix), but Vishay offers AEC-Q101 qualified versions under ordering codes such as SMBJ130CAHE3_B/I. These variants undergo extended stress testing for temperature cycling, humidity, and mechanical shock. For automotive use, specify the HE3 or HM3 suffix and verify qualification status via Vishay's official documentation-SMBJ130CA-E3/5B alone does not carry AEC-Q101 certification.
How does the bidirectional design of SMBJ130CA-E3/5B affect its PCB layout?
The SMBJ130CA-E3/5B has no polarity marking and functions identically in both directions, eliminating orientation constraints during placement. Unlike unidirectional variants (e.g., SMBJ130A-E3/5B), it requires no cathode band alignment-reducing assembly errors and enabling use on AC-coupled, differential, or floating signal paths. This simplifies layout for applications like RS-485 buses or transformer-isolated power supplies where voltage polarity reverses.
What is the thermal resistance of SMBJ130CA-E3/5B, and how does it impact derating?
SMBJ130CA-E3/5B has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" copper pads per terminal. At ambient temperatures above 25 °C, its peak pulse power must be derated per Figure 2 in document 88392-e.g., at 75 °C ambient, usable PPPM drops to ~420 W. Continuous power dissipation remains limited to 5.0 W regardless of pulse duty cycle.
Can SMBJ130CA-E3/5B replace SMBJ130A-E3/5B in an existing design?
SMBJ130CA-E3/5B can replace SMBJ130A-E3/5B only if the circuit relies on bidirectional clamping and lacks polarity-sensitive components. Since SMBJ130CA-E3/5B has no cathode marking and conducts equally in both directions, it may cause unintended conduction in unidirectionally biased paths. Verify signal rail grounding topology and ensure no forward-biased junctions exist before substitution-SMBJ130CA-E3/5B is not a drop-in replacement without layout review.
