Product details
Overview
LCE10-E3/54 from Vishay General Semiconductor is a unidirectional low-capacitance TRANSZORB® transient voltage suppressor (TVS) diode in the 1.5KE package, rated for 1500 W peak pulse power (10/1000 µs), 10 V stand-off voltage (VWM), and 17.0 V maximum clamping voltage (VC) at 88 A peak pulse current. It protects sensitive ICs and MOSFETs against inductive switching transients and lightning surges in telecom and industrial signal lines.
For engineers reviewing the LCE10-E3/54 datasheet, LCE10-E3/54 pinout, LCE10-E3/54 application, or LCE10-E3/54 equivalent, key selection criteria include its 10 V working voltage, 11.1–12.3 V breakdown range, 5.0 µA max reverse leakage at VWM, 175 °C max junction temperature, and UL 497B listing for telecom surge protection.
Technical Context
The LCE10-E3/54 employs a glass-passivated silicon junction to achieve fast response time (<1 ns) and low incremental surge resistance, enabling effective clamping of high-energy transients before downstream components are damaged. Its unidirectional polarity-marked by a cathode band-supports DC-biased protection paths without AC rectification effects.
Designed for repetitive surge events at 0.01 % duty cycle, it delivers stable 1500 W pulse handling with thermal derating above 25 °C ambient, supported by a 6.5 W steady-state power dissipation rating on an infinite heatsink at 75 °C lead temperature. The device meets JESD 22-B106 solderability (275 °C, 10 s) and JESD 201 Class 1A whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10.0 V - Maximum continuous reverse operating voltage before significant leakage begins; sets upper limit for protected line DC bias. |
| VBR (min/max) | 11.1 V / 12.3 V - Breakdown occurs within this range at 1 mA test current; defines threshold for clamping activation. |
| VC @ IPP | 17.0 V @ 88 A - Clamped voltage during 10/1000 µs surge; determines worst-case overvoltage seen by protected circuit. |
| PPPM | 1500 W - Peak pulse power capability per 10/1000 µs waveform; quantifies transient energy absorption capacity. |
| ID @ VWM | 5.0 µA - Reverse leakage at stand-off voltage; ensures minimal loading on low-power signal lines. |
| TJ max | 175 °C - Maximum allowable junction temperature; enables operation in high-ambient industrial environments. |
| Package | 1.5KE - Axial-leaded, molded epoxy case meeting UL 94 V-0; compatible with through-hole PCB assembly and manual rework. |
Pinout & Package
Package: 1.5KE axial-leaded molded epoxy case (0.375" lead length, 0.210" body diameter), RoHS-compliant matte tin-plated leads, cathode indicated by color band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Non-marked lead | Connected to lower-potential side (e.g., ground or return path) in unidirectional TVS configuration. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10A | 600 W PPPM, SMC package, 17.0 V VC @ 35.1 A, 10.0 V VWM | Lower power rating suits space-constrained consumer electronics; not UL 497B listed. | Select when board area is limited and surge threat level is ≤IEC 61000-4-5 Level 2. |
| 1.5KE10A | Identical electrical specs and 1.5KE package; differs only in packaging suffix (bulk vs. tape/reel) and RoHS compliance grade. | No functional difference; suitable for same telecom and industrial designs requiring UL 497B validation. | Choose for cost-sensitive production where E3/54 tape-and-reel logistics are unnecessary. |
Compared with SMBJ10A and 1.5KE10A, the LCE10-E3/54 offers identical clamping performance and UL 497B certification in a RoHS-compliant tape-and-reel format optimized for automated assembly-making it preferred for high-volume telecom infrastructure and industrial OEM programs requiring traceable sourcing and regulatory alignment.

FAQ
What is the clamping voltage of the LCE10-E3/54 under a standard 10/1000 µs surge?
The LCE10-E3/54 has a maximum clamping voltage (VC) of 17.0 V at 88 A peak pulse current under the 10/1000 µs waveform. This value is measured per Figure 3 in Vishay document 88357 and defines the upper voltage limit imposed on protected circuits during surge events. Designers use this parameter to verify that downstream components remain within their absolute maximum ratings when the LCE10-E3/54 activates.
Is the LCE10-E3/54 suitable for AC signal line protection?
No-the LCE10-E3/54 is unidirectional and intended for DC-biased lines. For AC signal protection, Vishay's application note specifies using two LCE10-E3/54 devices in parallel but opposite polarity. A single LCE10-E3/54 would conduct during the negative half-cycle of AC, causing failure. Always follow the dual-diode anti-parallel configuration shown in Figure 4 of document 88357 when applying the LCE10-E3/54 to AC circuits.
Does the LCE10-E3/54 meet UL 497B requirements for telecom surge protection?
Yes-the LCE10-E3/54 is UL listed under file number E136766 for Telecom Application Protection per UL 497B. This certification confirms its suitability for primary-side protection in telephone line interface circuits, including DSL, T1/E1, and analog voice systems. The UL listing applies directly to the LCE10-E3/54 as shipped, with no additional qualification required by end-equipment manufacturers.
What is the maximum operating temperature for the LCE10-E3/54 junction?
The LCE10-E3/54 has a maximum junction temperature (TJ) rating of +175 °C, as specified in the "Maximum Ratings" table of Vishay document 88357. This allows reliable operation in high-ambient environments such as industrial motor drives or outdoor telecom cabinets. Thermal design must ensure that power dissipation-especially under repetitive surges-does not cause sustained junction temperatures beyond this limit.
How does the LCE10-E3/54 differ from the standard 1.5KE10A in terms of compliance and packaging?
The LCE10-E3/54 and 1.5KE10A share identical electrical characteristics and 1.5KE package dimensions, but the LCE10-E3/54 carries the E3 suffix indicating RoHS compliance and JESD 201 Class 1A whisker resistance, and ships in 13" paper tape-and-reel (54 mm reel width, 1400 units per reel). The 1.5KE10A may be offered in bulk or alternate packaging without guaranteed RoHS or whisker testing-making the LCE10-E3/54 the preferred choice for regulated production environments.
