Product details
Overview
1.5KE13-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 and automotive control modules.
For engineers reviewing the 1.5KE13-E3/54 datasheet, 1.5KE13-E3/54 pinout, 1.5KE13-E3/54 application, or 1.5KE13-E3/54 equivalent, this page delivers verified electrical parameters, JEDEC 1.5KE package details, clamping performance under surge conditions, thermal derating behavior, and direct alternative options for circuit protection redesign or BOM optimization.
Technical Context
This unidirectional TVS diode operates as a voltage-clamped shunt protector: when transient voltage exceeds VBR, it avalanches into low-impedance conduction, diverting surge current away from downstream components. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<5.0 µA at VWM).
It delivers 1500 W peak pulse power handling per 10/1000 µs waveform with 0.01 % duty cycle, supports 200 A non-repetitive forward surge (8.3 ms half-sine), and maintains operation across –55 °C to +175 °C junction temperature range - enabling use in harsh-environment power conversion and motor drive circuits.
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 detection |
| VWM | 11.1 V - maximum continuous reverse operating voltage before leakage rises above 5.0 µA |
| VC @ 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 power dissipation capability with standard 10/1000 µs test waveform |
| IFSM | 200 A - single-cycle surge current rating (8.3 ms half-sine), critical for inductive switch-off protection |
| TJ max. | +175 °C - enables deployment in high-temperature environments like engine control units or enclosed power converters |
| RθJA | 75 °C/W - thermal resistance from junction to ambient, informs heatsinking requirements for sustained power dissipation |
Pinout & Package
Package: JEDEC DO-201AD (Case Style 1.5KE), axial-leaded molded epoxy body with matte tin-plated leads; RoHS-compliant, commercial grade (E3 suffix); 0.375" (9.5 mm) lead length standard.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side of protected line; conducts during positive transients when cathode is biased higher |
| Cathode | Avalanche conduction terminal | Marked by color band; connected to higher-potential rail; initiates clamping when voltage exceeds VBR |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Ensures stable VBR tolerance (±5 %) and low leakage (<5 µA) over lifetime and temperature |
| 1500 W peak pulse power | Handles lightning-induced surges (IEC 61000-4-5 Level 4) without degradation when properly mounted |
| Sub-nanosecond response time | Clamps within <1 ns - faster than MOVs or polymer-based protectors, preserving signal integrity in high-speed lines |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients (e.g., ESD or inductive kickback) |
| UL 94 V-0 flammability rating | Mold compound self-extinguishes, meeting safety requirements for enclosed industrial and automotive enclosures |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13A | DO-214AA package (smaller footprint), 13.0 V VBR min, 14.4 V VC @ 74.1 A, 600 W PPPM | Lower power rating suits space-constrained consumer electronics; not suitable for 1500 W industrial surges | Select SMBJ13A only when board area is limited and peak surge energy is ≤600 W; verify thermal margin with RθJA = 110 °C/W |
| 1.5KE13A-E3/54 | Same electrical specs and package as 1.5KE13-E3/54; identical VBR, VC, and PPPM; differs only in part numbering convention (no functional difference) | No application difference - fully interchangeable in all designs using 1.5KE13-E3/54 | 1.5KE13A-E3/54 is a documented alternate marking; no layout or qualification changes required |
Compared with 1.5KE13-E3/54, SMBJ13A offers compact size but sacrifices 60 % peak power capacity and thermal robustness, while 1.5KE13A-E3/54 provides identical protection performance with standardized JEDEC 1.5KE packaging and sourcing continuity.

FAQ
What is the breakdown voltage range of the 1.5KE13-E3/54?
The 1.5KE13-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 standards. This tight tolerance ensures consistent clamping behavior across production lots and supports precise overvoltage threshold design in 12 V systems. The 1.5KE13-E3/54 achieves this via glass-passivated junction processing, minimizing parameter drift over temperature and life.
How does the 1.5KE13-E3/54 differ from bidirectional TVS diodes like 1.5KE13CA?
The 1.5KE13-E3/54 is unidirectional and protects only against positive transients on the cathode side, with a defined anode–cathode polarity marked by a band. In contrast, 1.5KE13CA is bidirectional and symmetrical, suppressing both positive and negative surges - making it suitable for AC lines or differential data buses. The 1.5KE13-E3/54 cannot replace 1.5KE13CA in AC-coupled applications due to its inherent polarity dependence.
What is the maximum clamping voltage of the 1.5KE13-E3/54 under surge conditions?
The 1.5KE13-E3/54 clamps to a maximum of 18.2 V when subjected to its rated 82.4 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is measured at the device terminals and represents the upper bound of voltage seen by protected circuitry during worst-case surge events. Designers use this VC to verify that downstream ICs remain within their absolute maximum ratings - for example, ensuring compatibility with 20 V-tolerant microcontrollers.
Can the 1.5KE13-E3/54 be used in automotive applications?
Yes, the 1.5KE13-E3/54 meets key automotive requirements: it operates from –55 °C to +175 °C, withstands 200 A 8.3 ms surge (per ISO 16750-2 Pulse 5a), and is RoHS-compliant. While not AEC-Q101 qualified itself (the HE3 variant is), its construction and thermal performance make it suitable for non-safety-critical automotive subsystems such as HVAC controls or lighting modules where qualification is not mandated.
What is the thermal resistance of the 1.5KE13-E3/54, and how does it affect layout?
The 1.5KE13-E3/54 has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W under standard test conditions (lead length 0.375"). This means each watt of sustained power dissipation raises junction temperature by ~75 °C above ambient. For reliable operation, PCB layout must include adequate copper pour on both leads and avoid enclosing the device - especially important when used in repetitive surge scenarios or high-temperature enclosures. The 1.5KE13-E3/54's RθJL of 15.4 °C/W further emphasizes the need for short, wide traces to minimize thermal bottleneck at the leads.
