Product details
Overview
1.5KE110C-E3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode designed for high-energy surge protection in power and signal lines. It features a 110 V breakdown voltage (VBR = 105–116 V), 1500 W peak pulse power (10/1000 µs), and clamps transients to ≤152 V at 9.9 A, making it suitable for protecting MOSFETs, ICs, and sensor interfaces in industrial and automotive systems.
For engineers reviewing the 1.5KE110C-E3/54 datasheet, 1.5KE110C-E3/54 pinout, 1.5KE110C-E3/54 application, or 1.5KE110C-E3/54 equivalent, this device offers verified bidirectional clamping, UL 497B recognition, RoHS-compliant matte tin leads, and AEC-Q101 qualification options - critical for robust overvoltage design in harsh environments.
Technical Context
This TVS operates as a voltage-clamped shunt protector with symmetrical avalanche breakdown in both polarities. Its glass-passivated junction enables sub-nanosecond response time (<1 ns), low incremental surge resistance, and stable clamping under repetitive 10/1000 µs transients at 0.01% duty cycle.
Designed for unclamped transient suppression, it exhibits a maximum reverse standoff voltage (VWM) of 94.0 V, leakage current ≤1.0 µA at VWM, and thermal resistance of 15.4 °C/W (junction-to-lead), supporting reliable operation up to TJ = 175 °C without heatsinking in moderate-power applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 105 V / 116 V - ensures reliable avalanche conduction onset within tight tolerance for predictable clamping threshold |
| VWM | 94.0 V - maximum continuous reverse operating voltage before significant leakage begins |
| VC @ IPPM | 152 V - clamped voltage during 9.9 A 10/1000 µs surge, defining worst-case stress on downstream circuitry |
| PPPM | 1500 W - peak transient power handling capability per single 10/1000 µs pulse |
| IPPM | 9.9 A - maximum non-repetitive surge current the device safely clamps without failure |
| TJ max. | 175 °C - maximum junction temperature enabling use in under-hood automotive and industrial ambient conditions |
| Package | Case Style 1.5KE - axial-leaded DO-201AD package with 0.375" lead length, UL 94 V-0 molded epoxy body |
Pinout & Package
1.5KE110C-E3/54 uses a two-terminal axial-leaded DO-201AD (Case Style 1.5KE) package. As a bidirectional TVS, it has no polarity marking; both terminals are functionally identical and interchangeable in circuit layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient shunt path | Both terminals conduct identically in either direction during overvoltage events; no cathode band or polarity identification required |
| Leads (matte tin plated) | PCB interface and thermal path | Solderable per J-STD-002/JESD 22-B102; supports 275 °C solder dip (10 s); RθJL = 15.4 °C/W enables self-heating management |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable, repeatable avalanche characteristics and long-term reliability under repeated surge stress |
| Bidirectional clamping | Provides symmetrical protection against positive and negative transients without external polarity constraints |
| UL 497B recognition (QVGQ2) | Validates suitability for telecom and industrial surge protection systems requiring certified safety compliance |
| 1500 W 10/1000 µs rating | Supports IEC 61000-4-5 Level 4 (4 kV) surge immunity when properly routed and decoupled |
| AEC-Q101 qualified variants available | Enables drop-in qualification path for automotive powertrain and body electronics where reliability is mission-critical |
Applications
| Industrial Motor Drives | Automotive Power Distribution |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ110CA | DO-214AA (SMB) package, lower PPPM = 600 W, same VBR range (105–116 V), higher IPPM = 5.9 A | Surface-mount only; unsuitable for through-hole designs or high-thermal-mass PCBs | Select when board space is constrained and thermal budget allows reduced surge margin |
| 1.5SMC110CA | DO-214AB (SMC) package, PPPM = 1500 W, identical VBR/VC, but 20% larger footprint than 1.5KE | Higher thermal mass improves repetitive surge endurance but requires larger pad layout | Choose for enhanced reliability in high-cycle industrial environments where leaded mounting is not mandatory |
Compared with 1.5KE110C-E3/54, SMBJ110CA trades axial-leaded robustness and thermal performance for compact SMT integration, while 1.5SMC110CA retains full 1500 W capability in a surface-mount form - neither is pin-compatible, but both serve overlapping surge protection roles with distinct mechanical and thermal trade-offs.

FAQ
What is the breakdown voltage tolerance for 1.5KE110C-E3/54?
The 1.5KE110C-E3/54 has a specified breakdown voltage (VBR) range of 105 V to 116 V at 1.0 mA test current, representing a ±5% tolerance around the nominal 110 V rating. This tight tolerance ensures predictable clamping behavior in precision protection circuits and aligns with JEDEC standard 1.5KE series specifications documented in Vishay's 88301 datasheet.
Is 1.5KE110C-E3/54 RoHS compliant and lead-free?
Yes, the "E3" suffix in 1.5KE110C-E3/54 indicates full RoHS compliance per EU Directive 2011/65/EU, with matte tin-plated leads and halogen-free molding compound. It meets JESD 201 Class 1A whisker testing requirements and carries Vishay's material compliance certification per document 99912.
Does 1.5KE110C-E3/54 have AEC-Q101 qualification?
The base 1.5KE110C-E3/54 is commercial-grade; however, the AEC-Q101 qualified variant is designated as 1.5KE110CHE3_B (with revision code "B"). That version undergoes extended stress testing per AEC-Q101 Rev D and is approved for automotive powertrain and chassis applications - confirmation requires checking the specific part number's packaging label or Vishay's qualified parts list.
What is the maximum clamping voltage of 1.5KE110C-E3/54 under surge conditions?
The maximum clamping voltage (VC) of 1.5KE110C-E3/54 is 152 V at its rated peak pulse current (IPPM) of 9.9 A, measured using the standardized 10/1000 µs double-exponential waveform. This value defines the upper voltage limit imposed on protected circuitry during worst-case transient events and is validated per JEDEC test methods in the 88301 datasheet.
Can 1.5KE110C-E3/54 be used in bidirectional AC line protection?
Yes, 1.5KE110C-E3/54 is explicitly designed for bidirectional applications, with identical electrical characteristics in both polarities. Its 110 V nominal breakdown and 94.0 V standoff voltage make it suitable for clamping AC line transients up to ~132 VRMS, provided proper coordination with upstream fusing and thermal derating per Vishay's Fig. 2 and Fig. 5 derating curves is applied.
