Product details
Overview
1.5KE110CHE3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for robust overvoltage protection in power rails and signal lines. It features a 110 V breakdown voltage (VBR = 105–116 V at 1 mA), 94.0 V maximum standoff voltage (VWM), and clamps transients to ≤152 V at 9.9 A peak pulse current (IPPM) under 10/1000 µs waveform. It delivers 1500 W peak pulse power and operates across –55 °C to +175 °C junction temperature, targeting automotive power supply inputs and industrial DC bus protection.
For engineers reviewing the 1.5KE110CHE3/54 datasheet, 1.5KE110CHE3/54 pinout, 1.5KE110CHE3/54 application, or 1.5KE110CHE3/54 equivalent, this page provides verified electrical parameters, thermal derating behavior, clamping performance curves, JEDEC-standard 1.5KE package dimensions, and AEC-Q101-qualified alternatives for automotive-grade design validation.
Technical Context
This TVS diode uses a glass-passivated silicon junction optimized for fast transient response (<1 ns) and low incremental surge resistance. Its unidirectional polarity enables cathode-referenced clamping on positive-going surges, with VF = 5.0 V at 100 A forward surge - critical for minimizing conduction loss during high-energy events.
The device complies with JEDEC standard 1.5KE case outline and supports 200 A non-repetitive forward surge current (IFSM) per 8.3 ms half-sine wave. Thermal resistance is RθJA = 75 °C/W (junction-to-ambient) and RθJL = 15.4 °C/W (junction-to-lead), enabling reliable operation under pulsed stress when mounted on PCBs with adequate copper pour or lead heatsinking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 105 V / 116 V at 1 mA test current - defines precise clamping onset threshold for overvoltage detection |
| VWM | 94.0 V - maximum continuous reverse operating voltage before leakage exceeds 1 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 transient energy absorption capability without failure |
| IFSM | 200 A (8.3 ms half-sine) - surge current handling for inductive switch-off events |
| TJ range | –55 °C to +175 °C - extended thermal envelope supporting under-hood automotive use |
| Package | JEDEC 1.5KE - axial-leaded, epoxy-molded case with UL 94 V-0 flammability rating |
Pinout & Package
JEDEC 1.5KE package: axial-leaded, molded epoxy body with cathode band marking; leads are matte tin-plated, solderable per J-STD-002 and JESD 22-B102; meets JESD 201 class 1A whisker test (E3 suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference node for reverse-biased clamping | Connected to system ground or low-side return path; conducts during negative transients only in bidirectional variants - not active in unidirectional 1.5KE110CHE3/54 |
| Cathode | Clamping output node | Connected to protected line (e.g., 12 V rail); sinks surge current to ground when VIN > VBR; color band identifies this terminal |

Applications
| Automotive Power Input Protection | Industrial DC Bus Clamping |
|---|---|

IC Role / Device Role / Timing Role: Unidirectional TVS placed between battery rail and ECU input capacitor to clamp transients above 94 V. Use Value: Limits voltage to ≤152 V during 100 ms, 120 V load dump event, preventing damage to downstream LDOs and microcontrollers in 1.5KE110CHE3/54-equipped designs. | Use Scenario: Safeguarding PLC analog I/O modules connected to 24 V DC field wiring exposed to inductive switching noise. IC Role / Device Role / Timing Role: Standoff-rated TVS on 24 V supply line to absorb repetitive 10/1000 µs transients from solenoid drivers. Use Value: Maintains system uptime by suppressing >1 kV spikes before they reach precision ADC front-ends, enabled by 1.5KE110CHE3/54's 1500 W rating and <1 ns response. |
| Telecom Line Interface Protection | Consumer Power Adapter Output Clamp |
Use Scenario: Shielding Ethernet PHY power pins from lightning-induced surges on PoE-powered devices. IC Role / Device Role / Timing Role: Secondary-level TVS on 48 V PoE input after primary isolation, rated for bidirectional threat but used unidirectionally here. Use Value: Ensures IEEE 802.3af compliance by limiting clamped voltage to 152 V, well below 200 V absolute max of integrated PMICs in 1.5KE110CHE3/54-based reference layouts. | Use Scenario: Preventing overvoltage damage to USB-C PD controller ICs during adapter hot-plug events with mismatched chargers. IC Role / Device Role / Timing Role: Final-stage clamping device on 20 V PPS output rail of GaN-based adapters.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ110A-E3/52 | Lower PPPM (600 W), SMC package (surface-mount), VC = 177 V @ 5.7 A | Not suitable for 1.5KE110CHE3/54's 1500 W requirement; better for space-constrained PCBs | Select only if board layout prohibits axial leads and surge energy is ≤600 W |
| 1.5KE110AHE3_B | Same electrical specs and 1.5KE package; AEC-Q101 qualified with revision code "B" | Identical function and footprint; certified for automotive under-hood use | Preferred drop-in replacement where AEC-Q101 compliance is mandatory - 1.5KE110CHE3/54 lacks qualification documentation |
Compared with 1.5KE110CHE3/54, SMBJ110A-E3/52 offers compactness at reduced surge capacity, while 1.5KE110AHE3_B delivers identical protection with formal automotive qualification - making it the technically aligned upgrade path for safety-critical systems requiring documented AEC-Q101 validation.

FAQ
What is the breakdown voltage tolerance for 1.5KE110CHE3/54?
The 1.5KE110CHE3/54 has a specified breakdown voltage range of 105 V to 116 V at 1 mA test current, corresponding to ±5 % tolerance around the nominal 110 V rating. This tight VBR window ensures consistent clamping behavior across production lots and supports predictable overvoltage protection margins in designs using the 1.5KE110CHE3/54.
Is 1.5KE110CHE3/54 AEC-Q101 qualified?
No, 1.5KE110CHE3/54 is not AEC-Q101 qualified. The HE3 suffix indicates RoHS compliance and commercial-grade construction; AEC-Q101 qualification applies only to variants with revision codes such as "B" (e.g., 1.5KE110AHE3_B). For automotive applications requiring formal qualification, engineers must select the AEC-Q101 variant instead of the 1.5KE110CHE3/54.
What is the maximum clamping voltage of 1.5KE110CHE3/54 at rated peak pulse current?
The maximum clamping voltage (VC) of 1.5KE110CHE3/54 is 152 V when subjected to its rated peak pulse current of 9.9 A under the standard 10/1000 µs waveform. This value is measured per JEDEC test conditions and defines the upper voltage limit imposed on protected circuits during worst-case surge events - a key parameter verified in every 1.5KE110CHE3/54 production lot.
Can 1.5KE110CHE3/54 be used in bidirectional configurations?
No, 1.5KE110CHE3/54 is a unidirectional TVS diode and cannot provide symmetrical clamping for AC or bipolar transients. Bidirectional operation requires the "CA" suffix (e.g., 1.5KE110CA). The "H" in 1.5KE110CHE3/54 denotes RoHS compliance and commercial grade, not polarity - polarity is fixed as unidirectional per the part numbering convention and datasheet specifications for the 1.5KE110CHE3/54.
What is the thermal resistance of 1.5KE110CHE3/54 and how does it affect PCB layout?
The 1.5KE110CHE3/54 has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W and junction-to-lead resistance (RθJL) of 15.4 °C/W. To maintain safe operation during repetitive surges, PCB layout must provide ≥0.5 in² (320 mm²) of 2 oz copper pour connected to both leads - insufficient copper area will cause junction temperature to exceed 175 °C, degrading 1.5KE110CHE3/54 reliability and clamping consistency.
