Product details
Overview
LCE8.0A-E3/54 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in the 1.5KE package, rated for 1500 W peak pulse power (10/1000 μs), 8.0 V stand-off voltage (VWM), and 13.6 V maximum clamping voltage (VC) at 100 A peak pulse current. It features glass-passivated junction, UL 94 V-0 molded epoxy case, and is designed for protecting MOSFETs, ICs, and sensor signal lines against inductive switching transients and lightning surges in industrial and telecom systems.
For engineers reviewing the LCE8.0A-E3/54 datasheet, LCE8.0A-E3/54 pinout, LCE8.0A-E3/54 application, or LCE8.0A-E3/54 equivalent, key selection criteria include verified clamping performance at 100 A, unidirectional polarity with cathode band marking, RoHS-compliant matte tin leads, and compatibility with J-STD-002 solderability standards under 275 °C/10 s dip conditions.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds its breakdown threshold (min. 8.89 V, max. 9.83 V at 1 mA), it avalanches to divert surge current away from downstream circuitry. Its low incremental surge resistance ensures stable clamping during repetitive 10/1000 μs pulses at 0.01% duty cycle.
The device is optimized for fast response (<1 ns typical), low junction capacitance (100 pF at 0 V), and high reliability across -65 °C to +175 °C operating junction temperature. It meets UL 497B for telecom line protection (File E136766) and supports AC line protection when paired with an anti-parallel unit per Fig. 4.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 8.0 V - Maximum continuous reverse working voltage before significant leakage; defines safe operating margin below breakdown. |
| VBR (min/max) | 8.89 V / 9.83 V at 1 mA - Confirmed avalanche initiation range; ensures predictable turn-on under surge conditions. |
| VC @ IPP | 13.6 V at 100 A - Measured clamping voltage during 10/1000 μs pulse; determines maximum stress on protected IC. |
| PPPM | 1500 W - Peak pulse power handling capability; validates robustness against IEC 61000-4-5 Level 4 surges. |
| Junction Capacitance | 100 pF at 0 V - Low capacitance preserves signal integrity on high-speed data lines (e.g., RS-485, CAN). |
| TJ max. | +175 °C - Maximum junction temperature rating; enables operation in high-ambient industrial environments. |
| Polarity | Unidirectional - Cathode marked by color band; suitable for DC-biased lines where reverse conduction is not required. |
Pinout & Package
Package: 1.5KE molded epoxy case (Case Style 1.5KE), UL 94 V-0 rated, with matte tin-plated leads. Dimensions: 0.375" (9.5 mm) lead length, 0.210"–0.285" body width, axial lead configuration.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ8.0A | Lower peak power (600 W), SMC package (smaller footprint), same VWM/VC specs. | Better suited for space-constrained PCBs; insufficient for 1500 W IEC 61000-4-5 Level 4 testing. | Select SMBJ8.0A only if surge energy requirements are ≤600 W and board area is critical. |
| 1.5KE8.0A | Identical electrical specs and 1.5KE package; differs only in packaging suffix (E3/54 vs. standard tape/reel codes). | No functional difference; both meet UL 497B and JESD 201 Class 1A. | 1.5KE8.0A is a direct form-fit-function alternative with identical performance and qualification. |
Compared with SMBJ8.0A and 1.5KE8.0A, the LCE8.0A-E3/54 delivers full 1500 W surge capability in a RoHS-compliant, UL-listed 1.5KE package with verified 100 pF capacitance-making it optimal for high-energy telecom and industrial protection where both power rating and certification are mandatory.

FAQ
What is the breakdown voltage range for LCE8.0A-E3/54?
The LCE8.0A-E3/54 has a minimum breakdown voltage (VBR) of 8.89 V and a maximum of 9.83 V, measured at 1 mA test current per the Vishay datasheet (Doc. #88357). This range ensures consistent avalanche initiation across production lots while maintaining margin above its 8.0 V stand-off voltage. The LCE8.0A-E3/54 must be selected with this tolerance in mind for precise clamping design.
Is LCE8.0A-E3/54 suitable for AC signal line protection?
No - the LCE8.0A-E3/54 is unidirectional and intended for DC-biased lines. For AC signal protection (e.g., telephone lines), Vishay specifies use of two LCE8.0A-E3/54 units in anti-parallel configuration per Figure 4 of the datasheet. This arrangement provides symmetrical clamping for both polarities while retaining the device's 100 pF capacitance and UL 497B compliance. The LCE8.0A-E3/54 alone cannot protect bidirectional AC waveforms.
Does LCE8.0A-E3/54 meet RoHS and lead-free assembly requirements?
Yes - the "E3" suffix confirms LCE8.0A-E3/54 is RoHS-compliant per Directive 2011/65/EU and features matte tin-plated leads qualified to J-STD-002 solderability standards. It also passes JESD 201 Class 1A whisker testing. The LCE8.0A-E3/54 supports lead-free reflow and wave soldering up to 275 °C for 10 seconds, making it compatible with modern commercial PCB assembly processes.
What is the maximum clamping voltage of LCE8.0A-E3/54 at rated surge current?
The LCE8.0A-E3/54 exhibits a maximum clamping voltage (VC) of 13.6 V when subjected to a 100 A peak pulse current with a 10/1000 μs waveform, as specified in the Electrical Characteristics table (Doc. #88357, page 2). This value defines the upper voltage limit imposed on protected circuitry during worst-case surge events and is critical for ensuring compatibility with 5 V or 3.3 V logic interfaces downstream of the LCE8.0A-E3/54.
How does LCE8.0A-E3/54 differ from standard 1.5KE8.0A parts?
The LCE8.0A-E3/54 shares identical electrical specifications, package (1.5KE), and UL 497B listing with generic 1.5KE8.0A devices but adds the "E3/54" ordering code indicating RoHS compliance, JESD 201 Class 1A whisker testing, and packaging in 13" paper tape/reel (1400 units per reel). The LCE8.0A-E3/54 is functionally interchangeable with 1.5KE8.0A in all circuit implementations where these qualifications are required.
