Product details
Overview
SMBG130AHE3/52 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMBG (DO-215AA) package, designed for robust overvoltage protection of DC power rails and signal lines. 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 rating with 10/1000 μs waveform - used in automotive power supply inputs and industrial sensor interfaces.
For engineers reviewing the SMBG130AHE3/52 datasheet, SMBG130AHE3/52 pinout, SMBG130AHE3/52 application, or SMBG130AHE3/52 equivalent, key selection criteria include clamping performance under repetitive surge stress, AEC-Q101 qualification for automotive use, thermal resistance (RθJA = 100 °C/W), unidirectional polarity marking, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (<1.0 μA reverse leakage at 130 V), but triggers into low-impedance conduction when transient voltage exceeds its breakdown threshold. Its glass-passivated junction ensures stable VBR tolerance (±5 %) and long-term reliability under thermal cycling.
The device is rated for 100 A non-repetitive forward surge current (8.3 ms half-sine), supports operating junction temperatures from –55 °C to +150 °C, and meets J-STD-020 MSL Level 1 with 260 °C reflow peak - confirming suitability for high-volume, lead-free PCB assembly without moisture sensitivity concerns.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 130 V - maximum continuous reverse working voltage before clamping initiates |
| VBR (min/max) | 144 V / 159 V at IT = 1 mA - defines precise turn-on threshold for overvoltage response |
| VC @ IPPM | 209 V at 2.9 A - clamping voltage during full 600 W transient, limiting downstream stress |
| PPPM | 600 W - peak pulse power handling with 10/1000 μs waveform, 0.01 % duty cycle |
| IFSM | 100 A - single half-sine surge current rating (8.3 ms), critical for load-dump immunity |
| TJ max | +150 °C - maximum junction temperature, enabling operation in under-hood automotive environments |
| RθJA | 100 °C/W - thermal resistance junction-to-ambient on standard 5.0 mm × 5.0 mm pads |
Pinout & Package
Package: SMBG (DO-215AA), surface-mount, low-profile gull-wing lead frame with matte tin-plated terminals solderable per J-STD-002 and JESD 22-B102. Cathode indicated by band marking on body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point in forward bias | Connected to protected circuit ground or low-side return path during clamping |

| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients (e.g., ESD, inductive switching) |
Applications
| Automotive Power Input Protection | Industrial Sensor Signal Line Protection |
|---|---|
Use Scenario: Protecting 12 V/24 V battery-fed ECUs against load dump transients up to 120 V and ISO 7637-2 Pulse 5a. IC Role / Device Role / Timing Role: Unidirectional shunt TVS placed between power rail and chassis ground to clamp overvoltage before it reaches LDOs or microcontrollers. Use Value: Limits peak voltage to ≤209 V at 2.9 A, preventing damage to downstream 36 V-rated regulators and ensuring system-level EMC compliance. | Use Scenario: Safeguarding analog outputs (e.g., 4–20 mA current loops) and digital I/O (CAN, LIN) from ESD and inductive kickback in factory automation sensors. IC Role / Device Role / Timing Role: Low-capacitance (<50 pF typical at 0 V) unidirectional TVS mounted directly at connector interface. Use Value: Clamps transients within <1 ns while maintaining signal integrity - verified by <1.0 μA leakage at 130 V ensures no DC loading on precision sensor circuits. |
| Telecom DC Power Feeds | Consumer Device USB/DC Jack Protection |
Use Scenario: Securing -48 V telecom rectifier outputs against lightning-induced surges and hot-swap transients in base station power distribution. IC Role / Device Role / Timing Role: High-energy TVS installed upstream of DC-DC converters and PMICs to absorb multi-kW surge energy. Use Value: 600 W rating and 100 A IFSM enable reliable protection against IEC 61000-4-5 Level 4 (4 kV/2 kA) events without derating. | Use Scenario: Hardening external DC input jacks (e.g., 12–19 V laptop adapters) against user-induced surges and miswiring in portable electronics. IC Role / Device Role / Timing Role: Primary overvoltage barrier placed immediately after barrel jack, before input fuse and buck controller. Use Value: AEC-Q101 qualification and RoHS-compliant HE3 suffix ensure long-term field reliability and regulatory acceptance in global consumer markets. |
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 | Same VWM/VBR/VC, but SMB (DO-214AA) package - 1.58 mm height vs. SMBG's 1.14 mm | Less suitable for ultra-low-profile designs; higher RθJA (125 °C/W) reduces power handling in compact layouts | Select SMBG130AHE3/52 when board height <1.2 mm or thermal pad area is limited to 5 mm² per terminal |
| 1.5SMC130AHE3/A | Same electrical specs, but larger SMC (DO-214AB) package - 2.79 mm height, 1.0 mm lead pitch | Higher surge margin (1500 W PPPM) but incompatible with fine-pitch SMT lines and dense automotive PCBs | Choose SMBG130AHE3/52 for AEC-Q101-compliant space-constrained modules where footprint and reflow compatibility are prioritized over raw power headroom |
Compared with SMBJ130A-E3/52 and 1.5SMC130AHE3/A, SMBG130AHE3/52 delivers identical clamping performance in a lower-profile, thermally optimized package with validated automotive qualification - making it the preferred choice for next-generation ADAS domain controllers and compact power management units.

FAQ
What is the clamping voltage of SMBG130AHE3/52 at its rated peak pulse current?
The SMBG130AHE3/52 has a maximum clamping voltage (VC) of 209 V when subjected to its peak pulse current (IPPM) of 2.9 A under a 10/1000 μs waveform. This value is measured per Figure 1 in Vishay document 88456 and defines the upper voltage limit imposed on protected circuitry during surge events - critical for ensuring downstream ICs remain within absolute maximum ratings.
Is SMBG130AHE3/52 suitable for automotive applications?
Yes, SMBG130AHE3/52 is AEC-Q101 qualified (as confirmed in the "MECHANICAL DATA" section of Vishay document 88456), with HE3 suffix denoting RoHS compliance and automotive qualification. It supports junction temperatures from –55 °C to +150 °C and withstands 100 A surge current - meeting requirements for engine control, body electronics, and ADAS power rail protection.
What does the "HE3/52" suffix mean in SMBG130AHE3/52?
The "HE3" suffix indicates RoHS-compliant, AEC-Q101-qualified construction with matte tin-plated leads; "/52" denotes packaging in 7″ diameter plastic tape and reel, with 750 units per reel. This ordering code aligns with Vishay's standardized format shown in the "ORDERING INFORMATION" table on page 3 of document 88456.
How does SMBG130AHE3/52 differ from bidirectional TVS diodes like SMBG130CA?
SMBG130AHE3/52 is unidirectional and features polarity marking (cathode band), enabling use in DC circuits where reverse conduction must be blocked. In contrast, SMBG130CA is bidirectional with symmetrical clamping in both directions and no polarity marking - intended for AC lines or differential data paths like RS-485, not for DC power rail protection.
What is the thermal resistance of SMBG130AHE3/52, and how does it affect layout design?
SMBG130AHE3/52 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 assumes minimum recommended pad layout per Figure 5 in document 88456 - underscoring the need for adequate copper area to sustain repeated 600 W pulses without exceeding +150 °C junction temperature.
