Product details
Overview
LCE16-E3/54 from Vishay General Semiconductor is a unidirectional low-capacitance TRANSZORB® transient voltage suppressor (TVS) diode designed for robust overvoltage protection of sensitive signal lines and power rails. It features a 16.0 V stand-off voltage (VWM), 17.8–19.7 V breakdown voltage (VBR), 1500 W peak pulse power (10/1000 μs), 26.0 V maximum clamping voltage at 57 A, and operates across –65 °C to +175 °C junction temperature range.
For engineers reviewing the LCE16-E3/54 datasheet, LCE16-E3/54 pinout, LCE16-E3/54 application, or LCE16-E3/54 equivalent, key selection criteria include its unidirectional polarity, 1.5KE package compatibility, UL 497B listing for telecom surge protection, and verified clamping performance under repetitive 0.01% duty cycle transients.
Technical Context
The LCE16-E3/54 employs a glass-passivated chip junction and molded epoxy case meeting UL 94 V-0 flammability rating. Its low incremental surge resistance and fast response time enable effective suppression of inductive switching spikes and lightning-induced surges on signal paths feeding ICs and MOSFETs.
Rated for 1500 W peak pulse power with 10/1000 μs waveform and derated linearly above 25 °C, it delivers stable clamping up to 26.0 V at 57 A while maintaining ≤100 pF junction capacitance - critical for high-speed data line protection without signal integrity degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 16.0 V - Maximum continuous reverse operating voltage before conduction begins; defines safe signal rail margin. |
| VBR (min/max) | 17.8 V / 19.7 V - Breakdown occurs within this range at 1 mA test current; ensures predictable turn-on threshold. |
| VC @ IPP | 26.0 V at 57 A - Clamped voltage during 10/1000 μs surge; limits downstream device stress below safe limits. |
| PPPM | 1500 W - Peak transient energy absorption capability; supports high-energy ESD and lightning surge events. |
| Junction Capacitance | ≤100 pF at 0 V - Enables use on USB 2.0, RS-485, CAN, and other <10 Mbps signal lines without bandwidth loss. |
| Operating Temperature | –65 °C to +175 °C - Supports deployment in automotive engine compartments and industrial motor drives. |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16A | Same VWM (16 V), but lower PPPM = 600 W and higher VC = 26.0 V @ 24.7 A; DO-214AA package. | Lower surge handling capacity; suitable only for non-repetitive, low-duty-cycle events. | Select SMBJ16A only when board space constraints preclude 1.5KE footprint and surge energy is <500 W. |
| 1.5KE16A | Identical electrical specs and 1.5KE package; differs only in packaging suffix (bulk vs. tape/reel) and JEDEC compliance level. | No functional difference; identical use cases and mounting. | 1.5KE16A is a direct form-fit-function alternative with identical thermal and clamping behavior. |
Compared with SMBJ16A and 1.5KE16A, the LCE16-E3/54 offers superior surge endurance (1500 W vs. 600 W) and UL 497B certification not found in standard SMBJ series - making it preferred for telecom infrastructure and industrial control where regulatory compliance and multi-event reliability are mandatory.

FAQ
What is the maximum clamping voltage of the LCE16-E3/54 under surge conditions?
The LCE16-E3/54 has a maximum clamping voltage (VC) of 26.0 V at 57 A peak pulse current using the standard 10/1000 μs waveform. This value is measured per Figure 3 in Vishay document 88357 and represents the upper limit of voltage seen by downstream circuitry during a full-rated transient event. The LCE16-E3/54 maintains this clamping performance across its full operating temperature range.
Is the LCE16-E3/54 RoHS-compliant and halogen-free?
Yes, the LCE16-E3/54 carries the "E3" suffix indicating full RoHS compliance per Directive 2011/65/EU and adherence to JEDEC JS709A halogen-free standards. The matte tin-plated leads meet J-STD-002 solderability requirements, and the molding compound is UL 94 V-0 rated. These attributes are confirmed in Vishay document 88357 and material category policy documentation.
Can the LCE16-E3/54 be used for bidirectional transient protection?
No - the LCE16-E3/54 is a unidirectional TVS diode, intended for DC or single-polarity signal line protection. For AC or bidirectional applications like RS-485 or Ethernet, two LCE16-E3/54 units must be connected in series opposition (anode-to-anode or cathode-to-cathode), as shown in Figure 4 of Vishay document 88357. Using a single LCE16-E3/54 on an AC line risks reverse breakdown failure.
What is the junction capacitance of the LCE16-E3/54 and why does it matter?
The LCE16-E3/54 has a maximum junction capacitance of 100 pF at 0 V, measured per Vishay specification table in document 88357. This low value minimizes signal loading on high-speed lines such as CAN, USB 2.0, and sensor analog outputs - preserving edge rates and preventing data corruption or measurement error in precision applications.
Does the LCE16-E3/54 require heatsinking for continuous operation?
No external heatsink is required for transient suppression duty, as the LCE16-E3/54 is rated for 6.5 W power dissipation on an infinite heatsink at TL = 75 °C. Its 1.5KE package provides sufficient thermal mass for short-duration pulses. However, for sustained power dissipation above 100 mW, PCB copper area and thermal vias should be optimized per Vishay's thermal design guidelines in document 88357.
