Product details
Overview
1.5KE110CA-E3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode designed for clamping voltage transients on signal and power lines. It features a 110 V breakdown voltage (VBR min/max = 105–116 V), 1500 W peak pulse power (10/1000 µs), 152 V maximum clamping voltage at 9.9 A, 1.0 mA test current, and 94.0 V stand-off voltage - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the 1.5KE110CA-E3/54 datasheet, 1.5KE110CA-E3/54 pinout, 1.5KE110CA-E3/54 application, or 1.5KE110CA-E3/54 equivalent, this page delivers verified electrical parameters, bidirectional clamping behavior, JEDEC 1.5KE package details, thermal resistance (RθJL = 15.4 °C/W), and AEC-Q101-qualified alternatives for automotive-grade surge protection design.
Technical Context
This device operates as a silicon avalanche diode with glass-passivated junction, enabling bidirectional transient suppression without polarity marking. Its clamping action responds in <1 ns, with low incremental surge resistance and stable performance across -55 °C to +175 °C junction temperature range.
It complies with UL 497B (QVGQ2 recognition), meets JESD 201 Class 1A whisker testing (E3 suffix), and uses molded epoxy packaging rated UL 94 V-0. The 1.5KE110CA-E3/54 is not AEC-Q101 qualified - only HE3-suffix variants (e.g., 1.5KE110CAHE3_B) carry that qualification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 105 V / 116 V - ensures reliable avalanche conduction onset within defined tolerance at 1.0 mA test current |
| VWM | 94.0 V - maximum continuous reverse operating voltage before leakage exceeds 1.0 µA |
| VC @ IPPM | 152 V - clamped voltage during 9.9 A 10/1000 µs surge, limiting downstream stress |
| PPPM | 1500 W - peak transient power handling capability under standardized 10/1000 µs waveform |
| RθJL | 15.4 °C/W - thermal resistance from junction to lead, critical for PCB copper pour sizing |
| TJ max | +175 °C - maximum junction temperature, supporting high-ambient industrial and under-hood automotive use |

Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Enables stable, repeatable avalanche characteristics and long-term reliability under repetitive surge stress |
| 1500 W peak pulse power (10/1000 µs) | Supports robust protection against IEC 61000-4-5 Level 4 surges (4 kV line-earth) when properly mounted |

Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor inputs (e.g., pressure, temperature) from load dump and ESD in vehicle ECUs. IC Role / Device Role / Timing Role: Bidirectional voltage clamp placed across differential signal pair or supply rail to shunt transients before reaching sensitive ASICs. Use Value: Limits induced surge voltage to ≤152 V during 9.9 A 10/1000 µs events, preserving signal integrity and preventing latch-up in 5 V/12 V sensor interfaces. | Use Scenario: Safeguarding digital input modules in programmable logic controllers exposed to inductive switching noise from solenoids and contactors. IC Role / Device Role / Timing Role: Parallel-connected TVS on 24 V DC input lines to absorb repetitive 1500 W surges without degradation. Use Value: Maintains system uptime by preventing false triggering and component failure during factory floor electromagnetic interference events. |
| Telecom Line Interface | Consumer Power Adapter Input |
Use Scenario: Shielding Ethernet PHYs and DSL line drivers from lightning-induced surges on outdoor copper pairs per R.E.A. P.E. 60. IC Role / Device Role / Timing Role: Primary-level surge suppressor placed before gas discharge tube (GDT) or secondary TVS in hybrid protection schemes. Use Value: Clamps fast-rising transients (<1 ns) to safe levels before GDT fires, reducing let-through energy to downstream circuitry. | Use Scenario: Secondary-side overvoltage protection on AC-DC adapter outputs feeding USB-C PD or smart home controllers. IC Role / Device Role / Timing Role: Standoff-rated (94.0 V) clamp suppressing output overshoot during regulator fault or capacitor discharge events. Use Value: Prevents damage to 5–20 V rated USB-PD controllers and microcontrollers during abnormal power-up or short-circuit recovery. |
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 | Lower PPPM (600 W), smaller SMB package (surface-mount), lower IPPM (32.3 A → 152 V clamping) | Preferred for space-constrained PCBs where 600 W surge rating suffices; lacks axial-leaded mechanical robustness | Select when board area is limited and peak surge energy is ≤600 W; verify thermal pad layout for SMBJ110CA's RθJA ≈ 50 °C/W |
| 1.5KE110CAHE3_B | Identical electrical specs but AEC-Q101 qualified; HE3 suffix denotes JESD 201 Class 2 whisker test and automotive qualification | Required for automotive OEM designs needing formal qualification evidence; same footprint and pinout | Choose for production automotive systems; note 1.5KE110CA-E3/54 is commercial grade only and not AEC-Q101 certified |
Compared with 1.5KE110CA-E3/54, SMBJ110CA trades surge capacity for compactness, while 1.5KE110CAHE3_B adds automotive qualification without altering electrical behavior - enabling drop-in replacement only where qualification compliance is mandatory.

FAQ
What is the breakdown voltage range of the 1.5KE110CA-E3/54?
The 1.5KE110CA-E3/54 has a specified breakdown voltage (VBR) range of 105 V to 116 V at 1.0 mA test current, measured per JEDEC standard. This tolerance ensures predictable clamping onset across manufacturing lots and temperature extremes, directly supporting design margin calculations for 94.0 V stand-off applications.
Is the 1.5KE110CA-E3/54 AEC-Q101 qualified?
No, the 1.5KE110CA-E3/54 is a commercial-grade part. Only variants with the HE3 suffix (e.g., 1.5KE110CAHE3_B) are AEC-Q101 qualified. The E3 suffix confirms RoHS compliance and JESD 201 Class 1A whisker resistance, but does not imply automotive qualification - critical for Tier 1 supplier documentation requirements.
What is the maximum clamping voltage for the 1.5KE110CA-E3/54 under surge conditions?
The 1.5KE110CA-E3/54 exhibits a maximum clamping voltage (VC) of 152 V at its rated peak pulse current (IPPM) of 9.9 A, tested with a 10/1000 µs waveform. This value defines the upper voltage limit imposed on protected circuitry during worst-case transient events and must be compared against downstream IC absolute maximum ratings.
How does the 1.5KE110CA-E3/54 differ from unidirectional 1.5KE110A-E3/54?
The 1.5KE110CA-E3/54 is bidirectional with symmetrical clamping in both polarities and no cathode band marking; the unidirectional 1.5KE110A-E3/54 has a cathode band, conducts only in reverse bias, and provides forward conduction path (VF ≈ 3.5 V at 100 A). Use CA for AC-coupled or differential lines; use A for DC rails with defined polarity.
What package type and lead finish does the 1.5KE110CA-E3/54 use?
The 1.5KE110CA-E3/54 uses JEDEC Case Style 1.5KE - an axial-leaded, molded epoxy package with matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards. The E3 suffix confirms RoHS compliance and JESD 201 Class 1A whisker resistance, validated for 275 °C solder dip (10 s max).
