Product details
Overview
1.5KE130A-E3/51 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode designed for primary overvoltage protection of DC power rails and signal lines. It features a 124 V to 137 V breakdown voltage (VBR), 111 V maximum standoff voltage (VWM), 179 V clamping voltage at 8.4 A peak pulse current, 1500 W peak pulse power rating (10/1000 µs), and operates across –55 °C to +175 °C junction temperature. It is used in automotive power supply inputs and industrial sensor interface protection.
For engineers reviewing the 1.5KE130A-E3/51 datasheet, 1.5KE130A-E3/51 pinout, 1.5KE130A-E3/51 application, or 1.5KE130A-E3/51 equivalent, this page delivers verified electrical parameters, thermal derating behavior, clamping performance under surge conditions, RoHS-compliant packaging details, and direct alternative part comparisons for ESD and lightning transient protection design.
Technical Context
This unidirectional TVS diode uses a glass-passivated silicon junction optimized for fast response (<1 ns) and low incremental surge resistance. Its clamping action begins at VBR = 124–137 V and limits transient voltages to ≤179 V at IPPM = 8.4 A (10/1000 µs waveform), with thermal resistance RθJL = 15.4 °C/W enabling robust surge handling without heatsinking for short-duration events.
The device complies with JEDEC standards for transient suppression and supports repetitive surge duty cycles up to 0.01 %, with VF = 5.0 V at 100 A forward surge (per note 3). It is rated for 200 A non-repetitive IFSM (8.3 ms half-sine) and exhibits a VBR temperature coefficient of +0.107 %/°C - critical for stable clamping across wide ambient ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 124 V / 137 V - defines minimum and maximum voltage at which clamping initiates reliably at 1 mA test current |
| VWM | 111 V - maximum continuous reverse operating voltage before leakage exceeds 1 µA |
| VC @ IPPM | 179 V at 8.4 A - peak clamped voltage during 10/1000 µs surge, limiting downstream stress |
| PPPM | 1500 W - peak transient power dissipation capability, enabling protection against lightning-induced surges |
| IPPM | 8.4 A - maximum non-repetitive peak pulse current supported under standard 10/1000 µs waveform |
| TJ range | –55 °C to +175 °C - enables deployment in under-hood automotive and high-temperature industrial environments |
| RθJL | 15.4 °C/W - low junction-to-lead thermal resistance supports self-heating management during repeated transients |
Pinout & Package
Package: DO-201AD (Case Style 1.5KE), axial-leaded, molded epoxy body meeting UL 94 V-0; matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards.
| Pin/Terminal | Circuit Role | Design Meaning |

| Cathode (banded end) | Clamping reference terminal | Marked with color band; reverse-biased during normal operation; initiates avalanche breakdown above VWM |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enables stable, repeatable avalanche characteristics and long-term reliability under repeated surge stress |
| 1500 W peak pulse power (10/1000 µs) | Supports IEC 61000-4-5 Level 4 (4 kV) surge immunity in properly designed front-end circuits |
| Sub-nanosecond response time | Clamps transients before sensitive ICs experience overvoltage damage - faster than MOVs or GDTs |
| RoHS-compliant, commercial-grade (E3 suffix) | Meets JESD 201 Class 1A whisker resistance; suitable for lead-free reflow and wave soldering processes |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (e.g., EFT/burst), improving clamping precision |
Applications
| Automotive Power Input Protection | Industrial Sensor Signal Line Protection |
|---|---|
Use Scenario: 12 V battery-fed ECUs exposed to load dump (ISO 7637-2 Pulse 5a) and alternator switching transients. IC Role / Device Role / Timing Role: Primary shunt protector placed upstream of DC-DC converters and LDOs to clamp surges before they reach regulation circuitry. Use Value: Limits transient voltage to ≤179 V at 8.4 A, preventing latch-up or gate oxide rupture in downstream MOSFETs and controllers. |
Use Scenario: 4–20 mA current loop interfaces in PLC analog input modules subject to field wiring induced surges. IC Role / Device Role / Timing Role: Unidirectional TVS placed across loop terminals to divert induced common-mode transients away from op-amp input stages. Use Value: Clamps within <1 ns to protect precision amplifiers with ±15 V supplies while maintaining signal integrity below 111 V standoff. |
| Telecom DC Power Feeds | Consumer Equipment AC/DC Adapter Inputs |
Use Scenario: -48 V telecom rectifier outputs feeding base station backplanes vulnerable to lightning-induced surges on distribution lines. IC Role / Device Role / Timing Role: Secondary-level TVS on board-level DC distribution, coordinated with upstream GDTs or MOVs for staged protection. Use Value: Provides precise, low-leakage clamping (≤1 µA at 111 V) to avoid loading nominal -48 V rail while surviving 1500 W pulses. |
Use Scenario: Secondary-side 12–24 V outputs of wall adapters powering IoT hubs, where internal wiring faults generate fast transients. IC Role / Device Role / Timing Role: Final-stage TVS across output terminals to prevent overvoltage damage to connected USB-C PD controllers or microcontrollers. Use Value: Delivers fail-safe clamping without affecting steady-state regulation due to tight VBR tolerance (±5.3 %) and low VF (5.0 V @ 100 A). |
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 | Lower PPPM (600 W), smaller SMB package (vs. DO-201AD), VC = 219 V @ 2.7 A | Better suited for space-constrained PCBs with lower-energy transients (IEC 61000-4-4); not rated for 1500 W lightning surges | Select SMBJ130A only if layout area is limited and surge threat level is ≤Level 3 per IEC 61000-4-5 |
| 1.5KE130CA | Bidirectional variant; same VBR/VC specs but symmetrical clamping for AC-coupled or floating lines | Required for protection of differential pairs (e.g., RS-485), transformer-coupled interfaces, or ungrounded sensor bridges | Choose 1.5KE130CA when protecting bidirectional signals or systems without defined ground reference |
Compared with 1.5KE130A-E3/51, SMBJ130A trades peak power and ruggedness for compactness, while 1.5KE130CA retains full 1500 W capability but enables symmetrical clamping - making the original optimal for cost-sensitive, high-energy unidirectional DC rail protection where DO-201AD mounting is acceptable.

FAQ
What is the breakdown voltage tolerance for 1.5KE130A-E3/51?
The 1.5KE130A-E3/51 has a specified breakdown voltage range of 124 V to 137 V at 1 mA test current, representing a ±5.3 % tolerance about the nominal 130 V rating. This tight VBR window ensures predictable clamping onset across production lots and temperature extremes, critical for coordinating with downstream overvoltage lockout thresholds in power management ICs.
Is 1.5KE130A-E3/51 suitable for automotive applications?
Yes, 1.5KE130A-E3/51 meets key requirements for automotive use including operation from –55 °C to +175 °C junction temperature, glass-passivated junction reliability, and compatibility with AEC-Q101-qualified variants in the same family (e.g., 1.5KE130AHE3_B). While the E3 suffix denotes commercial grade, its thermal and surge ratings align with under-hood power rail protection needs when applied per ISO 7637-2 Pulse 5a test profiles.
How does the clamping voltage of 1.5KE130A-E3/51 compare to its standoff voltage?
The 1.5KE130A-E3/51 has a maximum standoff voltage (VWM) of 111 V and a clamping voltage (VC) of 179 V at 8.4 A. This 68 V margin ensures reliable blocking during normal operation while providing sufficient headroom to limit transient overvoltage to safe levels for 12–24 V system components - a design balance validated by its 1500 W peak pulse rating and low incremental resistance.
Can 1.5KE130A-E3/51 be used in parallel for higher surge current handling?
Yes, multiple 1.5KE130A-E3/51 devices can be paralleled to increase total peak pulse current capacity, provided matched units are used and layout minimizes current imbalance (e.g., symmetrical trace lengths, shared thermal plane). Derating is required per Vishay's Fig. 2 - at 100 °C ambient, pulse power drops to ~70 % of rated 1500 W, so parallel configuration must account for thermal coupling and individual device derating.
What is the lead finish and solderability specification for 1.5KE130A-E3/51?
The 1.5KE130A-E3/51 features matte tin-plated leads compliant with J-STD-002 (solderability) and JESD 22-B102 (surface mount solderability testing), and passes JESD 201 Class 1A whisker testing. It supports both wave and reflow soldering, with maximum solder dip temperature of 275 °C for 10 seconds - ensuring robust interconnect integrity in high-volume manufacturing environments.
