Product details
Overview
LCE10A-E3/73 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode designed for robust overvoltage protection in DC power rails and signal lines. It features a 10.0 V stand-off voltage (VWM), 11.1–12.3 V breakdown voltage (VBR), 17.0 V maximum clamping voltage at 88 A peak pulse current, 1500 W peak pulse power (10/1000 µs), and operates up to 175 °C junction temperature.
For engineers reviewing the LCE10A-E3/73 datasheet, LCE10A-E3/73 pinout, LCE10A-E3/73 application, or LCE10A-E3/73 equivalent, key selection criteria include clamping performance under 88 A surge, unidirectional polarity with cathode band marking, RoHS-compliant matte tin-plated leads, and compatibility with J-STD-002 solderability standards for high-reliability industrial and telecom PCB assemblies.
Technical Context
The LCE10A-E3/73 employs a glass-passivated silicon junction for stable avalanche behavior and low incremental surge resistance. Its 10/1000 µs waveform response delivers precise clamping during fast transients induced by inductive switching or ESD events, with <1 ns intrinsic response time confirmed by TVS diode architecture.
Designed for single-polarity DC protection, it exhibits 5.0 µA maximum reverse leakage at VWM, 100 pF junction capacitance at 0 V, and meets UL 497B listing for telecom surge protection-enabling direct integration into base station power supplies and sensor interface circuits without additional filtering.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10.0 V - Maximum continuous reverse operating voltage before conduction begins; sets safe DC rail margin for 12 V systems. |
| VBR (min/max) | 11.1 V / 12.3 V at 1.0 mA - Confirmed avalanche onset range ensures predictable turn-on during overvoltage events. |
| VC @ IPP | 17.0 V at 88 A - Clamping voltage limits downstream IC stress during 1500 W transient surges. |
| PPPM | 1500 W - Peak pulse power rating per 10/1000 µs waveform defines surge energy handling capability. |
| Junction Capacitance | 100 pF at 0 V - Low capacitance preserves signal integrity on data lines up to ~10 MHz bandwidth. |
| Operating Temperature | -65 °C to +175 °C - Wide thermal range supports under-hood automotive and industrial power supply designs. |

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 | Same VWM (10 V), lower PPPM (600 W), DO-214AA package (smaller footprint) | Better suited for space-constrained consumer PCBs; insufficient for 1500 W telecom surges | Select SMBJ10A only if peak surge energy is ≤600 W and board area is critical. |
| 1.5KE10A | Identical electrical specs and 1.5KE package; legacy part number without E3 RoHS suffix | No functional difference; lacks JESD 201 Class 1A whisker testing and RoHS documentation traceability | Choose LCE10A-E3/73 for new designs requiring certified lead-free compliance and long-term supply assurance. |
Compared with SMBJ10A and 1.5KE10A, the LCE10A-E3/73 delivers identical clamping performance with enhanced reliability validation-its E3 suffix guarantees RoHS compliance and whisker resistance, while maintaining full 1500 W surge capacity required for industrial and telecom deployments where legacy 1.5KE10A may face obsolescence risk.

FAQ
What is the clamping voltage of the LCE10A-E3/73 under maximum surge conditions?
The LCE10A-E3/73 has a maximum clamping voltage (VC) of 17.0 V at 88 A peak pulse current (IPP), measured using the standardized 10/1000 µs waveform. This value ensures protected circuits remain below critical voltage thresholds during high-energy transients. The LCE10A-E3/73 maintains this clamping performance across its full operating temperature range of -65 °C to +175 °C.
Is the LCE10A-E3/73 suitable for AC line protection?
No-the LCE10A-E3/73 is a unidirectional TVS diode and must not be used alone on AC lines. For AC protection, two LCE10A-E3/73 units must be connected in series opposition (anode-to-anode or cathode-to-cathode) to provide bidirectional clamping. The LCE10A-E3/73 datasheet explicitly states this configuration requirement for AC signal line protection.
Does the LCE10A-E3/73 meet UL certification requirements for telecom applications?
Yes-the LCE10A-E3/73 is UL listed under file E136766 for Telecom Application Protection per UL 497B. This certification validates its suitability for primary-side surge protection in telecom infrastructure including DSLAMs, base stations, and central office equipment where standardized surge immunity is mandated.
What is the junction capacitance of the LCE10A-E3/73 and how does it affect signal integrity?
The LCE10A-E3/73 has a maximum junction capacitance of 100 pF at 0 V, enabling use on moderate-speed signal lines up to ~10 MHz without significant attenuation or timing skew. This low capacitance preserves rise/fall times in sensor interfaces and digital control signals, making the LCE10A-E3/73 appropriate for protecting analog outputs and low-frequency communication buses.
How does the E3 suffix impact the reliability and manufacturability of the LCE10A-E3/73?
The E3 suffix indicates RoHS-compliant construction with matte tin-plated leads qualified to JESD 201 Class 1A whisker resistance and solderable per J-STD-002. This ensures reliable reflow and wave soldering performance, eliminates tin whisker risk in high-reliability applications, and provides documented compliance with EU Directive 2011/65/EU-critical for automotive and industrial customers auditing supply chain materials.
