Product details
Overview
1.5KE130A-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection in 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 range - deployed in automotive power supply inputs and industrial sensor interface protection.
For engineers reviewing the 1.5KE130A-E3/54 datasheet, 1.5KE130A-E3/54 pinout, 1.5KE130A-E3/54 application, or 1.5KE130A-E3/54 equivalent, this page delivers verified electrical parameters, thermal derating behavior, JEDEC-standardized package dimensions, clamping performance curves, and direct replacement guidance for high-reliability transient suppression 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 limits transient-induced voltage excursions to ≤179 V at 8.4 A (10/1000 µs waveform), with thermal resistance of 15.4 °C/W (junction-to-lead) enabling robust surge handling without heatsinking under typical PCB trace conditions.
It complies with JEDEC standards for transient suppression, supports 200 A non-repetitive forward surge current (8.3 ms half-sine), and exhibits a temperature coefficient of VBR of +0.107 %/°C - ensuring predictable voltage threshold drift across operating temperature ranges in automotive and industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 124 V to 137 V - defines minimum and maximum voltage at which device enters avalanche conduction during transient events |
| VWM | 111 V - maximum continuous reverse working voltage before leakage exceeds 1 µA; sets upper limit for normal DC rail operation |
| VC @ IPPM | 179 V at 8.4 A - clamped voltage seen by protected circuit during full 1500 W transient; determines downstream component stress level |
| PPPM | 1500 W - peak pulse power dissipation capability with 10/1000 µs waveform; defines survivability against lightning-induced surges |
| IFSM | 200 A - non-repetitive forward surge current rating (8.3 ms half-sine); validates robustness against inductive switch-off spikes |
| TJ max. | +175 °C - maximum junction temperature; enables use in under-hood automotive and high-ambient industrial enclosures |
| RθJL | 15.4 °C/W - junction-to-lead thermal resistance; allows accurate thermal modeling when mounted on standard 0.375" lead length PCB traces |
Pinout & Package

Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip 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 surge immunity (4 kV line-to-ground) without external series impedance |

Applications
| Automotive Power Input Protection | Industrial Sensor Signal Line Protection |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs from load dump (ISO 16750-2) and alternator switching transients. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power rail and chassis ground to clamp transients above 111 V while remaining inert during normal operation. Use Value: Limits peak voltage to ≤179 V, preventing damage to 150 V-rated DC-DC converters and CAN transceivers upstream of the protection point. | Use Scenario: Shielding 4–20 mA analog sensor outputs in factory automation against ESD and inductive coupling from nearby motor drives. IC Role / Device Role / Timing Role: Low-capacitance TVS connected across differential signal pair to suppress common-mode surges without distorting slow analog signals. Use Value: Clamps transients within nanoseconds while adding <1 pF capacitance - preserving signal integrity up to 100 kHz bandwidth. |
| Telecom DC Power Feeds | Consumer Device USB Port Protection |
Use Scenario: Safeguarding PoE-powered equipment (IEEE 802.3af/at) from induced surges on 48 V DC input lines. IC Role / Device Role / Timing Role: Primary-level TVS on input side of DC-DC converter, coordinated with secondary-side TVS for staged protection. Use Value: Handles 1500 W surges without degradation, maintaining VWM margin above 48 V nominal and 57 V PoE max, ensuring no false triggering. | Use Scenario: Adding robust overvoltage defense to USB Type-A ports in smart home hubs exposed to accidental 12 V adapter misconnection. IC Role / Device Role / Timing Role: Unidirectional TVS tied between VBUS and ground to absorb >100 V transients before they reach USB controller ICs. Use Value: Clamps 100 V+ faults to <179 V in <1 ns, protecting 5.5 V tolerant USB PHYs and preventing latch-up or gate oxide rupture. |
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 peak pulse power (600 W), smaller SMB package (vs. DO-201AB), higher RθJA (110 °C/W) | Better suited for space-constrained consumer PCBs; insufficient for automotive load dump per ISO 16750-2 | Select 1.5KE130A-E3/54 when 1500 W surge handling and thermal robustness are required; choose SMBJ130A only for low-energy, board-area-limited designs. |
| 1.5SMC130A | Same 1500 W rating and VBR range, but SMC (DO-214AB) package with lower RθJL (12.5 °C/W) and surface-mount footprint | Requires rework of through-hole layout; better thermal performance on thermally enhanced pads but less mechanical ruggedness than axial leads | Prefer 1.5KE130A-E3/54 for high-vibration environments (e.g., automotive under-hood) where axial lead retention is critical; use 1.5SMC130A for automated SMT production with thermal pad optimization. |
Compared with SMBJ130A and 1.5SMC130A, the 1.5KE130A-E3/54 delivers superior mechanical stability via axial leads, proven thermal margin for sustained surge duty cycles, and legacy compatibility in existing through-hole designs - making it the preferred choice for industrial and automotive applications demanding field-proven ruggedness.

FAQ
What is the breakdown voltage tolerance of the 1.5KE130A-E3/54?
The 1.5KE130A-E3/54 has a specified breakdown voltage (VBR) range of 124 V to 137 V at 1.0 mA test current, representing a ±5.4 % tolerance around the nominal 130 V rating. This tight distribution ensures consistent clamping behavior across production lots and supports reliable system-level surge margin calculations in safety-critical designs.
Does the 1.5KE130A-E3/54 meet automotive qualification standards?
The 1.5KE130A-E3/54 is RoHS-compliant and commercial-grade; however, its AEC-Q101-qualified variant is designated as 1.5KE130AHE3_B. The E3/54 suffix indicates JEDEC-standard packaging (paper tape and reel) but does not imply automotive qualification. For automotive applications, specify the HE3_B version and verify qualification status via Vishay's official documentation.
How does the clamping voltage of the 1.5KE130A-E3/54 compare to its standoff voltage?
The 1.5KE130A-E3/54 has a maximum standoff voltage (VWM) of 111 V and a clamping voltage (VC) of 179 V at 8.4 A. This 68 V differential provides a defined safety margin - ensuring the device remains non-conductive during normal operation while limiting fault voltage to a known, survivable level during transients, critical for protecting downstream 150 V-rated components.
Can the 1.5KE130A-E3/54 be used in bidirectional configurations?
No - the 1.5KE130A-E3/54 is a unidirectional TVS diode, identified by the "A" suffix. Bidirectional variants use the "CA" suffix (e.g., 1.5KE130CA). Using the 1.5KE130A-E3/54 in AC or floating applications would result in forward conduction during negative half-cycles, causing failure. Select 1.5KE130CA only for true bidirectional surge suppression.
What is the thermal resistance profile of the 1.5KE130A-E3/54 under real PCB mounting conditions?
The 1.5KE130A-E3/54 has a typical junction-to-lead thermal resistance (RθJL) of 15.4 °C/W and junction-to-ambient (RθJA) of 75 °C/W. With standard 0.375" (9.5 mm) lead length and minimal copper pour, it sustains repetitive surges without exceeding 175 °C junction temperature - validated per Fig. 2 and Fig. 5 in Vishay document 88301. For high-duty-cycle use, thermal relief patterns on PCB leads are recommended.
