Product details
Overview
SMBJ130CA-E3/52 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 SMBJ130CA-E3/52 datasheet, SMBJ130CA-E3/52 pinout, SMBJ130CA-E3/52 application, or SMBJ130CA-E3/52 equivalent, key selection criteria include bidirectional clamping capability, 10/1000 μs surge rating, thermal resistance (RθJA = 100 °C/W), AEC-Q101 qualification eligibility, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates symmetrically in both directions due to its bidirectional CA construction, enabling suppression of positive and negative polarity transients without polarity-sensitive layout. Its glass-passivated junction ensures stable breakdown characteristics and low incremental surge resistance under repetitive 10/1000 μs surges at 0.01% duty cycle.
The device achieves clamping voltage (VC) of 209 V at IPPM, with temperature coefficient of VBR at +0.108 %/°C, and is rated for operation from –55 °C to +150 °C junction temperature. It meets UL 497B recognition (QVGQ2) and J-STD-020 MSL Level 1 (260 °C peak reflow).
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130CA-M3/52 | Halogen-free, RoHS-compliant variant with identical electrical specs and SMB package | No difference in circuit performance; selected when halogen-free compliance is mandated in final assembly | Choose M3/52 for green manufacturing programs requiring halogen-free bill-of-materials |
| SAC130CA | Same VWM/VBR/VC ratings but in SMC (DO-214AB) package - larger footprint, higher RθJA (75 °C/W) | Lower thermal efficiency and incompatible pad layout; requires PCB redesign | Select only if existing SMC footprint is fixed and higher surge margin (1.5 kW) justifies layout change |
Compared with SMBJ130CA-E3/52, the M3/52 offers identical protection performance with halogen-free materials, while SAC130CA trades compact SMB size for higher power handling in a physically larger package - making E3/52 optimal for space-constrained, high-volume SMT designs.

FAQ
What is the clamping voltage of SMBJ130CA-E3/52 at its rated peak pulse current?
The SMBJ130CA-E3/52 has a maximum clamping voltage (VC) of 209 V when subjected to its peak pulse current (IPPM) of 209 A under the standardized 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. The SMBJ130CA-E3/52 maintains this clamping performance across its full operating temperature range.
Is SMBJ130CA-E3/52 suitable for automotive applications?
SMBJ130CA-E3/52 itself is commercial-grade; however, the functionally identical SMBJ130CAHE3_B/H variant is AEC-Q101 qualified and approved for automotive use. Engineers specifying SMBJ130CA-E3/52 for automotive body electronics must verify whether AEC-Q101 compliance is contractually required - if so, the HE3 suffix version should be selected. The SMBJ130CA-E3/52 shares identical electrical parameters, package, and thermal behavior with its qualified counterpart.
How does the bidirectional design of SMBJ130CA-E3/52 affect PCB layout?
The SMBJ130CA-E3/52 has no polarity marking and operates identically in both directions, eliminating orientation constraints during placement. This allows direct placement across differential lines (e.g., RS-485 A/B), AC-coupled signals, or floating buses without cathode/anode alignment checks. Unlike unidirectional TVS diodes, the SMBJ130CA-E3/52 avoids risk of reverse-bias failure during negative transients - simplifying layout verification and reducing assembly errors in high-mix production.
What is the thermal resistance of SMBJ130CA-E3/52, and how does it impact derating?
The SMBJ130CA-E3/52 has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This value directly governs power derating above 25 °C ambient: for example, at 70 °C ambient, the device's 5.0 W steady-state power dissipation drops to ~3.3 W. Derating curves in Figure 2 of the Vishay datasheet (88392) must be applied to ensure TJ remains ≤150 °C under combined DC leakage and surge conditions - especially relevant in enclosed industrial enclosures.
Can SMBJ130CA-E3/52 replace SMBJ130A in an existing design?
No - SMBJ130CA-E3/52 is bidirectional, while SMBJ130A is unidirectional. Substituting them without circuit review risks failure: SMBJ130A conducts heavily in forward bias (VF ≤ 3.5 V at 50 A), whereas SMBJ130CA-E3/52 blocks in both directions until breakdown. Using SMBJ130CA-E3/52 in place of SMBJ130A on a DC power rail may cause unintended open-circuit behavior or excessive voltage drop. Always validate polarity requirements and transient directionality before interchanging A (unidirectional) and CA (bidirectional) variants of the SMBJ130 family.
