Product details
Overview
1.5KE110-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 105 V to 116 V breakdown voltage (VBR), 94.0 V maximum standoff voltage (VWM), 152 V clamping voltage at 9.9 A peak pulse current, 1500 W peak pulse power rating (10/1000 µs), and operates across -55 °C to +175 °C junction temperature range. It is used to protect MOSFETs, ICs, and sensor interfaces against lightning-induced surges and inductive switching transients.
For engineers reviewing the 1.5KE110-E3/54 datasheet, 1.5KE110-E3/54 pinout, 1.5KE110-E3/54 application, or 1.5KE110-E3/54 equivalent, this page delivers verified electrical parameters, JEDEC 1.5KE package details, clamping performance under standardized surge waveforms, thermal derating behavior, and RoHS-compliant commercial-grade sourcing status - all critical for automotive body electronics, industrial PLC I/O protection, and telecom power supply design.
Technical Context
This unidirectional TVS diode employs a glass-passivated silicon junction optimized for fast transient response (<1 ns) and low incremental surge resistance. Its clamping action begins at VBR = 105–116 V with 1.0 mA test current and limits voltage to ≤152 V at 9.9 A (10/1000 µs waveform), delivering precise overvoltage protection without crowbar behavior.
The device complies with JEDEC standard 1.5KE case style, uses matte tin-plated leads solderable per J-STD-002, and meets UL 94 V-0 flammability requirements. It supports repetitive surge duty cycles up to 0.01 % and exhibits a VBR temperature coefficient of +0.107 %/°C - enabling stable performance across extended industrial temperature ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 105 V / 116 V at 1.0 mA - defines reliable conduction onset threshold for overvoltage detection |
| VWM | 94.0 V - maximum continuous reverse operating voltage before leakage exceeds 1.0 µA |
| VC @ IPPM | 152 V at 9.9 A (10/1000 µs) - actual clamped voltage seen by protected circuit during surge |
| PPPM | 1500 W - peak surge energy handling capacity under standardized lightning-surge waveform |
| IFSM | 200 A (8.3 ms half-sine) - single-event forward surge current limit for unidirectional operation |
| TJ range | -55 °C to +175 °C - enables deployment in under-hood automotive, motor drive, and outdoor telecom environments |
| RθJA | 75 °C/W - thermal resistance from junction to ambient, critical for PCB copper pour and heatsinking decisions |
Pinout & Package
1.5KE110-E3/54 uses the industry-standard JEDEC 1.5KE molded epoxy package (Case Style 1.5KE), with axial leads and cathode band marking. The device has two terminals: anode and cathode. The cathode end is identified by a color band on the body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point in forward bias; connected to lower-potential side of protected line | Must be tied to ground or return path when protecting positive rail; determines polarity-sensitive placement |
| Cathode | Current exit point in forward bias; marked with color band; connected to higher-potential side | Defines unidirectional clamping direction - conducts only when cathode voltage exceeds anode by ≥VBR |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enables stable, repeatable VBR tolerance and long-term reliability under thermal cycling |
| 1500 W peak pulse power (10/1000 µs) | Supports IEC 61000-4-5 Level 4 surge immunity (4 kV line-to-ground) in properly designed layouts |
| Clamping voltage ≤152 V at 9.9 A | Provides margin below 160 V absolute maximum ratings of common 12 V/24 V automotive ICs and gate drivers |
| RoHS-compliant E3 suffix | Meets JESD 201 Class 1A whisker resistance, ensuring solder joint integrity in high-reliability assemblies |
| UL 94 V-0 molding compound | Prevents flame propagation in enclosure-constrained applications such as industrial control cabinets |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ110A | DO-214AA package; 110 V VWM; 170 V VC @ 8.8 A; 600 W PPPM | Lower power rating and higher clamping voltage; suited for space-constrained, lower-energy surge environments | Select SMBJ110A only if layout area is limited and surge threat level is ≤IEC 61000-4-5 Level 2 (2 kV) |
| 1.5KE110AHE3_B | Same 1.5KE package; identical VBR/VC/PPPM; AEC-Q101 qualified; HE3 whisker class 2 | Qualified for automotive powertrain and chassis applications requiring certified reliability | Choose 1.5KE110AHE3_B when automotive OEM qualification or extended temperature validation is mandatory |
Compared with 1.5KE110-E3/54, SMBJ110A offers smaller footprint but reduced surge robustness, while 1.5KE110AHE3_B provides identical protection performance with certified automotive reliability - making the latter suitable for safety-critical vehicle subsystems where 1.5KE110-E3/54 serves general industrial and telecom use cases.

FAQ
What is the breakdown voltage range for 1.5KE110-E3/54?
The 1.5KE110-E3/54 has a guaranteed breakdown voltage (VBR) range of 105 V to 116 V at 1.0 mA test current, measured per JEDEC standard. This range ensures consistent clamping onset across production lots and supports reliable overvoltage detection in 94 V standoff applications. The 1.5KE110-E3/54 maintains this specification across its full operating temperature range (-55 °C to +175 °C) with a +0.107 %/°C temperature coefficient.
Is 1.5KE110-E3/54 bidirectional or unidirectional?
The 1.5KE110-E3/54 is a unidirectional Transient Voltage Suppressor, indicated by the "A" suffix (not "CA"). It conducts only when the cathode voltage exceeds the anode by ≥VBR, making it suitable for DC rail protection where polarity is fixed. Bidirectional variants (e.g., 1.5KE110CA) exist in the same family but are distinct part numbers - the 1.5KE110-E3/54 itself is strictly unidirectional and marked with a cathode band.
What is the clamping voltage of 1.5KE110-E3/54 under surge conditions?
The 1.5KE110-E3/54 clamps to a maximum of 152 V when subjected to its rated 9.9 A peak pulse current (IPPM) under the standardized 10/1000 µs waveform. This value is measured per JEDEC test conditions and represents the actual voltage imposed on the protected circuit during worst-case surge events. The low clamping ratio (VC/VBR ≈ 1.45) confirms effective transient suppression capability.
Does 1.5KE110-E3/54 meet automotive qualification standards?
The 1.5KE110-E3/54 is a commercial-grade device with RoHS-compliant E3 termination and JESD 201 Class 1A whisker resistance, but it is not AEC-Q101 qualified. For automotive applications requiring formal qualification, the functionally identical 1.5KE110AHE3_B variant is available - it shares the same electrical specs and 1.5KE package but adds AEC-Q101 certification and Class 2 whisker resistance.
What package type does 1.5KE110-E3/54 use, and how is polarity identified?
The 1.5KE110-E3/54 uses the JEDEC-standard 1.5KE axial-leaded package (Case Style 1.5KE), with molded epoxy body meeting UL 94 V-0. Polarity is identified by a single color band on the cathode end of the device body - the banded end connects to the higher-potential side of the protected circuit. This marking is consistent across all unidirectional 1.5KE-A series parts, including the 1.5KE110-E3/54.
