Product details
Overview
SMBJ130A-E3/5B from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode 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 V maximum clamping voltage (VC) at 2.9 A peak pulse current, and 600 W peak pulse power capability with a 10/1000 µs waveform - deployed in power supply rails, I/O interfaces, and sensor signal lines across industrial and telecom systems.
For engineers reviewing the SMBJ130A-E3/5B datasheet, SMBJ130A-E3/5B pinout, SMBJ130A-E3/5B application, or SMBJ130A-E3/5B equivalent, this device is evaluated for high-energy surge immunity in DC power inputs, automotive body control modules, and Ethernet PHY protection where precise clamping level and low leakage (<1.0 µA at VWM) are critical selection criteria.
Technical Context
This unidirectional TVS diode operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 MΩ) with only 1.0 µA reverse leakage at 130 V; during transients exceeding VBR, it avalanches rapidly (<1 ns response) to clamp the line at ≤209 V while diverting up to 2.9 A (10/1000 µs). Its glass-passivated junction ensures stable breakdown characteristics and long-term reliability under repetitive surge stress.
Thermally, it uses an SMB (DO-214AA) package with RθJA = 100 °C/W and RθJL = 20 °C/W, enabling operation from –55 °C to +150 °C junction temperature. The cathode band marking identifies polarity, and its matte tin-plated leads comply with J-STD-002 solderability and JESD201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 130 V - Maximum continuous reverse operating voltage before conduction begins; defines safe DC working margin. |
| VBR (min/max) | 144 V / 159 V at 1 mA - Confirmed breakdown range ensuring predictable turn-on during surges above 130 V. |
| VC @ IPPM | 209 V at 2.9 A - Clamped voltage during full 600 W surge event; determines protected circuit's maximum transient exposure. |
| PPPM | 600 W - Peak pulse power handling per 10/1000 µs waveform; validates suitability for IEC 61000-4-5 Level 4 surges. |
| IPPM | 2.9 A - Peak surge current capacity at rated clamping voltage; sets minimum PCB trace width and fuse coordination. |
| ID @ VWM | ≤1.0 µA - Reverse leakage at stand-off voltage; critical for low-power sensor and battery-backed circuits. |
| TJ max | +150 °C - Maximum junction temperature; supports operation in enclosed industrial enclosures without active cooling. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile case with cathode band marking on one end. Dimensions: 4.57 mm × 3.94 mm × 2.20 mm (L × W × H); meets UL 94 V-0 flammability rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal during forward conduction | Connected to system ground or lower-potential rail; forms return path during transient clamping. |
| Cathode | Current exit terminal during reverse-biased clamping | Connected to protected line (e.g., 130 V supply rail); avalanche conduction occurs when voltage exceeds VBR. |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 µs) | Enables compliance with IEC 61000-4-5 surge immunity requirements for industrial equipment and telecom infrastructure. |
| Clamping ratio VC/VBR ≈ 1.38 | Indicates tight voltage regulation during surge events - lower ratio improves protection margin for downstream ICs. |
| 1.0 µA max reverse leakage at VWM | Minimizes standby power loss and avoids false triggering in high-impedance sensor bias networks. |
| MSL Level 1 (JEDEC J-STD-020) | Allows unlimited floor life and reflow compatibility at 260 °C peak without baking - simplifies SMT manufacturing. |
| Glass passivated junction | Ensures stable VBR tolerance and long-term reliability under thermal cycling and humidity exposure. |
Applications
| Industrial Power Supply Input Protection | Automotive Body Control Module (BCM) I/O Lines |

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-M3/5B | Halogen-free, RoHS-compliant variant with identical electrical specs and SMB package. | No functional difference; selected when halogen-free BOM compliance is mandated (e.g., EU public infrastructure projects). | Direct material substitution where halogen content restrictions apply; same layout and thermal performance. |
| SMCJ130A-E3/57 | Same VWM/VBR/VC ratings but in larger SMC (DO-214AB) package with 1500 W PPPM and higher IPPM (4.3 A). | Used where higher surge endurance is required (e.g., outdoor base station power inputs) and PCB space allows larger footprint. | Choose when system-level surge testing exceeds 600 W; requires PCB redesign due to larger 7.11 mm × 6.22 mm outline. |
Compared with SMBJ130A-E3/5B, the M3/5B offers identical protection performance with halogen-free construction, while the SMCJ130A-E3/57 delivers 2.5× higher surge power handling in a physically larger package - enabling tiered design flexibility across cost, compliance, and ruggedness requirements.

FAQ
What is the maximum clamping voltage of SMBJ130A-E3/5B under a 10/1000 µs surge?
The SMBJ130A-E3/5B has a maximum clamping voltage (VC) of 209 V when subjected to its rated peak pulse current of 2.9 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 surge events - critical for validating voltage tolerances of downstream components like MOSFETs or DC/DC controllers in the same design.
Is SMBJ130A-E3/5B RoHS-compliant and lead-free?
Yes, SMBJ130A-E3/5B is RoHS-compliant and lead-free. The "E3" suffix explicitly denotes Vishay's commercial-grade, RoHS-compliant construction with matte tin-plated leads that meet J-STD-002 solderability requirements. It also satisfies JEDEC JESD201 Class 2 whisker resistance testing, making it suitable for high-reliability automated assembly processes without post-solder cleaning concerns.
How does SMBJ130A-E3/5B differ from bidirectional variants like SMBJ130CA?
SMBJ130A-E3/5B is unidirectional and features a cathode band marking; it conducts only during reverse overvoltage events and blocks forward current. In contrast, SMBJ130CA is bidirectional with no polarity marking and symmetrical clamping in both directions - used for AC-coupled or differential signal lines. Electrical differences include doubled ID limit for VWM ≤10 V bidirectional types (not applicable here), but SMBJ130A-E3/5B maintains tighter leakage control (≤1.0 µA) ideal for DC rail protection.
What is the thermal resistance of SMBJ130A-E3/5B, and how does it affect PCB layout?
SMBJ130A-E3/5B has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on the recommended 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This value assumes standard FR-4 board thickness and no internal plane layers. To maintain TJ ≤150 °C under worst-case power dissipation, designers must ensure adequate copper area and avoid excessive trace length or narrow routing - especially important in high-temperature industrial enclosures where ambient may exceed 70 °C.
Can SMBJ130A-E3/5B be used in automotive applications?
SMBJ130A-E3/5B itself is commercial-grade; however, the functionally identical SMBJ130AHE3 variant is AEC-Q101 qualified for automotive use. While SMBJ130A-E3/5B shares the same electrical and mechanical specifications, it lacks the extended temperature cycling, humidity, and lifetime validation required for under-hood or safety-critical vehicle subsystems. For non-automotive applications such as industrial controls or telecom, SMBJ130A-E3/5B remains fully appropriate and widely deployed.
