Product details
Overview
SMBJ130C-E3/52 from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for robust overvoltage protection of sensitive electronics. It features a 130 V stand-off voltage (VWM), 144–159 V breakdown voltage (VBR at 1 mA), 209 A peak pulse current (IPPM) under 10/1000 µs waveform, and clamps to ≤209 V at rated surge, protecting MOSFETs, ICs, and sensor signal lines in industrial power supplies and telecom interfaces.
For engineers reviewing the SMBJ130C-E3/52 datasheet, SMBJ130C-E3/52 pinout, SMBJ130C-E3/52 application, or SMBJ130C-E3/52 equivalent, key selection criteria include clamping voltage margin relative to protected device's absolute maximum rating, thermal derating above 25 °C, IPPM capability versus system-level surge threat level (e.g., IEC 61000-4-5), and RoHS-compliant commercial-grade qualification with MSL Level 1 reflow compatibility.
Technical Context
This TVS diode operates as a voltage-clamping device in parallel with protected circuitry, entering avalanche conduction when reverse voltage exceeds VBR, limiting transient energy by diverting surge current to ground. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0 µA at VWM), while the unidirectional polarity (cathode-banded) enables DC-biased protection paths without forward-conduction interference.
The SMBJ130C-E3/52 delivers 600 W peak pulse power (10/1000 µs) with low incremental surge resistance and <1 ns response time, meeting ANSI/IEEE C62.35 standards. Thermal resistance is 100 °C/W (junction-to-ambient) on standard 0.2" × 0.2" copper pads, requiring layout-aware thermal management for repetitive surge events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 130 V - Maximum continuous reverse operating voltage before clamping begins; sets upper limit for normal circuit operation. |
| VBR (min/max) | 144 V / 159 V at 1 mA - Confirmed breakdown range defining reliable avalanche onset; ensures consistent clamping threshold across production lots. |
| VC @ IPPM | ≤209 V at 209 A - Clamped voltage during full-rated 600 W surge; must remain below protected device's absolute maximum rating. |
| IPPM | 209 A - Peak surge current handling capacity under standardized 10/1000 µs waveform; determines survivability against lightning or inductive switch transients. |
| PPPM | 600 W - Peak pulse power dissipation capability; defines energy absorption limit per transient event without failure. |
| TJ max. | +150 °C - Maximum junction temperature; constrains ambient operating range and PCB copper area requirements for thermal reliability. |
| Package | SMB (DO-214AA) - Surface-mount outline with 0.220" × 0.155" footprint; compatible with automated placement and J-STD-020 reflow (peak 260 °C). |
Pinout & Package
Package: SMB (DO-214AA), molded plastic case with matte tin-plated leads, polarity indicated by cathode band on unidirectional devices. Mounting requires 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal for rated power dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference node | Connected to circuit ground or lowest potential point; completes clamping path during reverse surge. |
| Cathode | Protected line input | Connected to line being protected (e.g., DC supply rail or signal trace); avalanche conduction occurs when voltage exceeds VBR relative to anode. |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 µs) | Enables protection against high-energy transients such as IEC 61000-4-5 Level 4 surges without degradation. |
| Low clamping ratio (VC/VBR ≈ 1.37) | Minimizes voltage overshoot during clamping, reducing stress on downstream ICs and MOSFETs. |
| MSL Level 1 moisture sensitivity | Allows unlimited floor life and standard reflow without baking, simplifying SMT manufacturing flow. |
| RoHS-compliant, commercial grade (E3 suffix) | Meets global environmental compliance requirements without halogen-free cost premium; suitable for non-automotive industrial use. |
| Glass passivated junction | Ensures stable VBR tolerance and low leakage (<1.0 µA) over temperature and lifetime, critical for long-term reliability. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130A-E3/52 | Unidirectional variant with identical VWM, VBR, and clamping specs; same SMB package and RoHS/E3 compliance. | No functional difference - SMBJ130C-E3/52 and SMBJ130A-E3/52 are identical in electrical performance and marking; "C" vs "A" suffix reflects historical Vishay internal coding, not specification divergence. | Select based on distributor stock availability; both meet identical design requirements for 130 V DC protection. |
| SMCJ130A-E3/52 | Same VWM and VBR, but higher 1500 W PPPM and 338 A IPPM in larger SMC (DO-214AB) package; RθJA = 50 °C/W vs 100 °C/W. | Required where surge threat exceeds 600 W (e.g., outdoor AC mains interfaces); demands larger PCB footprint and enhanced thermal pad area. | Choose SMBJ130C-E3/52 for space-constrained 600 W applications; upgrade to SMCJ130A-E3/52 only if validated surge testing exceeds SMBJ rating. |
Compared with SMBJ130C-E3/52, SMBJ130A-E3/52 offers no technical distinction and serves as a direct form-fit-function match, whereas SMCJ130A-E3/52 provides higher surge capacity at the cost of increased board area and thermal design complexity - making SMBJ130C-E3/52 optimal for compact, cost-sensitive industrial DC protection.

FAQ
What is the clamping voltage of SMBJ130C-E3/52 at its rated peak pulse current?
The SMBJ130C-E3/52 has a maximum clamping voltage (VC) of 209 V when subjected to its rated peak pulse current (IPPM) of 209 A under the standard 10/1000 µs waveform. This value is measured at TA = 25 °C on recommended 0.2" × 0.2" copper pads and defines the upper voltage limit imposed on protected circuitry during worst-case surge events. Designers must verify this clamping level remains safely below the absolute maximum ratings of downstream components.
Is SMBJ130C-E3/52 unidirectional or bidirectional, and how is polarity identified?
SMBJ130C-E3/52 is a unidirectional transient voltage suppressor, meaning it conducts only in reverse bias (anode-to-cathode) during overvoltage events. Polarity is marked by a distinct cathode band on the SMB (DO-214AA) package body - the banded end is the cathode and must be connected to the line being protected, while the unbanded end (anode) connects to ground or the reference potential. Bidirectional variants use a "CA" suffix (e.g., SMBJ130CA).
Does SMBJ130C-E3/52 meet automotive qualification standards?
No, SMBJ130C-E3/52 is a commercial-grade part with RoHS-compliant E3 suffix and is not AEC-Q101 qualified. For automotive applications, Vishay offers the SMBJ130AHE3 variant (with HE3 suffix), which carries AEC-Q101 qualification and is explicitly rated for automotive use. The "C" in SMBJ130C-E3/52 does not denote automotive compliance - it is a legacy Vishay internal code for unidirectional configuration, identical in spec to SMBJ130A-E3/52.
What is the maximum leakage current of SMBJ130C-E3/52 at its stand-off voltage?
The SMBJ130C-E3/52 exhibits a maximum reverse leakage current (ID) of 1.0 µA at its rated stand-off voltage (VWM) of 130 V and TA = 25 °C. This low leakage ensures minimal power loss and avoids signal distortion in high-impedance circuits such as sensor outputs or precision analog interfaces, supporting reliable long-term operation without affecting system bias conditions.
Can SMBJ130C-E3/52 be used in place of SMBJ130A-E3/52?
Yes, SMBJ130C-E3/52 can be used interchangeably with SMBJ130A-E3/52. Both share identical electrical specifications (VWM = 130 V, VBR = 144–159 V, VC ≤ 209 V, IPPM = 209 A), mechanical dimensions (SMB/DO-214AA), and RoHS/E3 compliance. The "C" and "A" suffixes reflect Vishay's internal device coding convention for unidirectional TVS diodes in this family and do not indicate functional or parametric differences - they are electrically and physically equivalent.
