Product details
Overview
1.5KE13A-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 12.4 V to 13.7 V breakdown voltage (VBR) at 1.0 mA test current, 11.1 V maximum standoff voltage (VWM), 18.2 V clamping voltage (VC) at 82.4 A peak pulse current, and 1500 W peak pulse power rating with 10/1000 µs waveform - used to safeguard MOSFETs, ICs, and sensor interfaces in industrial power supplies.
For engineers reviewing the 1.5KE13A-E3/54 datasheet, 1.5KE13A-E3/54 pinout, 1.5KE13A-E3/54 application, or 1.5KE13A-E3/54 equivalent, this part delivers verified transient suppression for 12 V DC systems requiring fast-response (<1 ns), high-energy surge handling with glass-passivated junction reliability and RoHS-compliant matte tin leads.
Technical Context
This unidirectional TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds VBR, it avalanches into low-impedance conduction to divert surge current away from downstream circuitry. Its 1500 W peak pulse power rating is specified under JEDEC-standard 10/1000 µs waveform with 0.01% duty cycle, and thermal resistance is 15.4 °C/W junction-to-lead.
The device exhibits 0.081 %/°C temperature coefficient of VBR, 5.0 µA max reverse leakage at VWM, and 3.5 V max forward voltage at 100 A - confirming suitability for high-current transient events without forward conduction interference in protected paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 12.4 V / 13.7 V at 1.0 mA - defines precise avalanche initiation threshold for reliable overvoltage triggering |
| VWM | 11.1 V - maximum continuous reverse operating voltage before leakage exceeds 5.0 µA |
| VC at IPPM | 18.2 V at 82.4 A - clamped voltage during full 1500 W surge, limiting stress on protected ICs |
| PPPM | 1500 W - peak transient energy absorption capability with 10/1000 µs waveform |
| TJ max | +175 °C - enables operation in high-temperature environments such as automotive engine compartments |
| RθJL | 15.4 °C/W - low thermal resistance ensures effective heat transfer to PCB copper or heatsink |
| Package | Case Style 1.5KE - axial-leaded DO-201AD package with 0.375" lead length, UL 94 V-0 rated epoxy body |
Pinout & Package
1.5KE13A-E3/54 uses the standard DO-201AD (Case Style 1.5KE) axial-leaded package. The cathode is marked by a color band on the body; polarity must be observed in series connection with protected circuits.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., ground or return path) in unidirectional clamp configuration |
| Cathode | Avalanche conduction terminal | Connected to protected line (e.g., 12 V rail); color band identifies this end for correct orientation |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Ensures stable VBR tolerance and long-term reliability under repeated surge stress |
| 1500 W peak pulse power | Handles lightning-induced surges per IEC 61000-4-5 Level 4 (4 kV) without degradation |
| Sub-nanosecond response time | Clamps transients within ≤1 ns - faster than MOVs or polymer-based protectors |
| RoHS-compliant E3 suffix | Meets JESD 201 Class 1A whisker resistance and J-STD-002 solderability standards |
| UL 94 V-0 epoxy case | Self-extinguishing housing prevents flame propagation in safety-critical enclosures |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13A | DO-214AA package, 13.3 V VBR min, 200 W PPPM, lower surge current rating (10.9 A) | Lower power handling limits use to sub-100 W surge environments; surface-mount only | Select SMBJ13A only for space-constrained PCBs where 1500 W rating is unnecessary |
| 1.5KE13CA | Bidirectional variant with same VBR range but symmetrical clamping in both polarities; not suitable for DC rail protection | Required only for AC-coupled or floating signal lines (e.g., audio, differential data) | Choose 1.5KE13CA only when protecting bidirectional signals - never as direct replacement for 1.5KE13A-E3/54 in unidirectional DC rails |
Compared with SMBJ13A and 1.5KE13CA, the 1.5KE13A-E3/54 provides uniquely high 1500 W surge capacity in an axial-leaded through-hole package, making it optimal for industrial and automotive DC power line protection where mechanical robustness and high-energy dissipation are mandatory.

FAQ
What is the breakdown voltage range of the 1.5KE13A-E3/54?
The 1.5KE13A-E3/54 has a guaranteed breakdown voltage (VBR) range of 12.4 V to 13.7 V at 1.0 mA test current, measured per JEDEC standard. This tight tolerance ensures consistent avalanche initiation across production lots and supports precise overvoltage threshold design in 12 V systems. The 1.5KE13A-E3/54 maintains this specification across its full operating temperature range of –55 °C to +175 °C.
Is the 1.5KE13A-E3/54 suitable for automotive applications?
Yes, the 1.5KE13A-E3/54 meets critical automotive requirements including 175 °C maximum junction temperature, glass-passivated junction stability, and RoHS-compliant matte tin plating qualified to JESD 201 Class 1A. While the base E3 suffix is commercial grade, the HE3 variant (e.g., 1.5KE13AHE3_B) is AEC-Q101 qualified - the 1.5KE13A-E3/54 itself is widely deployed in non-safety-critical automotive subsystems like body control modules and infotainment power rails.
What is the clamping voltage of the 1.5KE13A-E3/54 under surge conditions?
The 1.5KE13A-E3/54 clamps to a maximum of 18.2 V at its rated peak pulse current of 82.4 A, defined under the standard 10/1000 µs waveform. This clamping voltage directly determines the maximum stress imposed on downstream components - for example, ensuring that a 16 V-rated DC-DC converter remains within safe operating limits during surge events. The 1.5KE13A-E3/54 achieves this with low incremental surge resistance and sub-nanosecond response.
How does the 1.5KE13A-E3/54 differ from bidirectional TVS diodes like 1.5KE13CA?
The 1.5KE13A-E3/54 is unidirectional and functions only in reverse-bias avalanche mode, with a cathode band marking required for correct orientation on DC rails. In contrast, 1.5KE13CA is bidirectional and symmetric - it clamps equally in both polarities, making it suitable for AC signals or floating lines but unsuitable as a drop-in replacement for 1.5KE13A-E3/54 in unidirectional DC protection. Their VBR ranges overlap, but electrical behavior and application context are fundamentally distinct.
What package type and lead finish does the 1.5KE13A-E3/54 use?
The 1.5KE13A-E3/54 uses the DO-201AD (Case Style 1.5KE) axial-leaded package with 0.375" (9.5 mm) lead length and UL 94 V-0 rated epoxy body. Its leads are matte tin plated and compliant with J-STD-002 and JESD 22-B102 solderability standards. The E3 suffix confirms RoHS compliance and JESD 201 Class 1A whisker resistance - critical for long-term reliability in vibration-prone or high-humidity environments.
