Product details
Overview
1.5KE13CA-E3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode designed for clamping voltage transients on signal and power lines. It features a 13 V nominal breakdown voltage (VBR = 12.4–13.7 V at 1.0 mA), 1500 W peak pulse power rating (10/1000 µs), and clamps to ≤18.2 V at 82.4 A peak pulse current - used in automotive sensor protection, industrial I/O interfaces, and telecom line surge suppression.
For engineers reviewing the 1.5KE13CA-E3/54 datasheet, 1.5KE13CA-E3/54 pinout, 1.5KE13CA-E3/54 application, or 1.5KE13CA-E3/54 equivalent, this page delivers verified electrical specs, bidirectional clamping behavior, JEDEC 1.5KE package details, thermal derating curves, and direct alternatives for ESD/lightning transient protection design.
Technical Context
This bidirectional TVS operates symmetrically across both polarities with identical VBR, VWM, and clamping characteristics in forward and reverse directions. Its glass-passivated junction enables sub-nanosecond response time (<1 ns) and low incremental surge resistance, critical for protecting sensitive MOSFET gates and analog front-ends against inductive switching spikes.
The device complies with UL 497B for protector classification and meets JESD 201 Class 1A whisker resistance (E3 suffix). It is rated for -55 °C to +175 °C operating junction temperature and supports 0.01% duty cycle repetitive surge events per JEDEC standard test conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 12.4 V / 13.7 V at 1.0 mA - defines precise clamping onset threshold for bidirectional overvoltage events |
| VWM | 11.1 V - maximum continuous working voltage before leakage exceeds 5 µA; sets safe operating margin below breakdown |
| VC @ IPPM | ≤18.2 V at 82.4 A - clamped voltage during 10/1000 µs surge; determines protected circuit's maximum stress level |
| PPPM | 1500 W - peak pulse power handling capability; enables robust protection against lightning-induced surges (IEC 61000-4-5) |
| TJ max. | +175 °C - high junction temperature rating allows operation in under-hood automotive or industrial enclosures without derating |
| RθJL | 15.4 °C/W - low junction-to-lead thermal resistance supports reliable power dissipation into PCB copper or heatsinked leads |
Pinout & Package
Package: JEDEC Case Style 1.5KE - molded epoxy body with matte tin-plated leads, UL 94 V-0 rated, RoHS-compliant (E3 suffix), 0.968 g unit weight. Leads are solderable per J-STD-002 and JESD 22-B102; no polarity marking for bidirectional variants.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Bidirectional conduction path | No cathode band; terminals interchangeable - enables placement without orientation check on PCB |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable VBR tolerance and long-term reliability under thermal cycling and humidity exposure |
| 1500 W peak pulse power (10/1000 µs) | Supports Level 4 IEC 61000-4-5 surge immunity (4 kV line-to-earth) without external series impedance |
| Sub-nanosecond response time | Clamps transients before downstream ICs experience damaging overvoltage - critical for high-speed data lines |
| UL 497B recognized (QVGQ2) | Validates suitability for telecom and industrial safety-critical surge protection applications without additional certification |
| JESD 201 Class 1A whisker resistance | Prevents tin whisker growth in high-reliability automotive and aerospace deployments over extended service life |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor inputs (e.g., pressure, temperature) from load-dump and ISO 7637-2 pulses in vehicle ECUs. IC Role / Device Role / Timing Role: Bidirectional clamping element placed directly at connector entry point to shunt surge energy before reaching interface IC. Use Value: Clamps 10/1000 µs transients to ≤18.2 V while maintaining <5 µA leakage at 11.1 V - preserves signal integrity and avoids false triggering. |
Use Scenario: Safeguarding 24 V DC digital input modules in programmable logic controllers against field-wiring induced surges and relay coil flyback. IC Role / Device Role / Timing Role: Primary transient suppressor across input terminals, coordinated with series current-limiting resistor for IEC 61000-4-4 EFT immunity. Use Value: Handles 82.4 A peak pulse without degradation, enabling compliance with IEC 61000-4-5 Level 3 (2 kV line-to-ground) without derating. |
| Telecom Line Interface | Consumer Power Adapter Input |
Use Scenario: Surge protection on POTS (Plain Old Telephone Service) or DSL line cards exposed to lightning-induced longitudinal surges on outside plant wiring. IC Role / Device Role / Timing Role: Bidirectional TVS placed differential-mode across tip/ring pair to clamp common-mode and differential-mode transients simultaneously. Use Value: Symmetric VBR and VC ensure balanced clamping in both directions - prevents signal distortion and maintains line balance up to 1 MHz. |
Use Scenario: Secondary-side overvoltage suppression in AC/DC adapters after rectification, guarding against capacitor failure or regulator fault conditions. IC Role / Device Role / Timing Role: Fast-acting crowbar device across DC output to limit fault voltage to safe levels for connected USB or low-voltage peripherals. Use Value: 175 °C max junction temperature allows operation adjacent to hot-switching MOSFETs without thermal runaway risk. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13CA | Lower PPPM (600 W), smaller SMB package (3.5 mm × 4.6 mm), higher VC (21.5 V @ 27.3 A) | Better suited for space-constrained consumer electronics; insufficient for 4 kV IEC 61000-4-5 line-level surges | Select when board area is limited and surge threat level is ≤2 kV; verify thermal margin due to higher RθJA. |
| 1.5SMC13CA | Same PPPM (1500 W), SMC package (7.1 mm × 6.2 mm), identical VBR/VC specs, but higher IFSM (200 A vs. N/A for bidirectional) | Compatible with automated SMT placement; requires rework of footprint and thermal pad layout | Choose for surface-mount compatibility and improved manufacturability; retains full 1.5KE13CA-E3/54 electrical performance. |
Compared with 1.5KE13CA-E3/54, SMBJ13CA trades surge capacity for compactness, while 1.5SMC13CA matches its protection level in an SMT-optimized form factor - neither is pin-compatible, but both serve overlapping transient suppression roles with distinct mechanical integration trade-offs.

FAQ
What is the breakdown voltage tolerance of the 1.5KE13CA-E3/54?
The 1.5KE13CA-E3/54 has a guaranteed breakdown voltage range of 12.4 V to 13.7 V at 1.0 mA test current, per Vishay Document 88301. This ±5.4% tolerance ensures consistent clamping behavior across production lots and supports predictable circuit protection design without margin over-engineering.
Is the 1.5KE13CA-E3/54 RoHS compliant and lead-free?
Yes, the 1.5KE13CA-E3/54 carries the "E3" suffix, indicating full RoHS compliance per EU Directive 2011/65/EU and exemption 7a. Its matte tin-plated leads meet J-STD-002 solderability requirements and JESD 201 Class 1A whisker resistance, confirming suitability for lead-free reflow assembly.
Does the 1.5KE13CA-E3/54 have AEC-Q101 qualification?
No - the 1.5KE13CA-E3/54 is commercial-grade only. AEC-Q101 qualification applies only to variants with "HE3" suffix (e.g., 1.5KE13CAHE3_B), as explicitly stated in Note (2) on page 3 of Vishay Document 88301. For automotive applications requiring qualification, the HE3 variant must be specified.
What is the maximum clamping voltage of the 1.5KE13CA-E3/54 under surge conditions?
The 1.5KE13CA-E3/54 clamps to a maximum of 18.2 V at its rated peak pulse current of 82.4 A (10/1000 µs waveform). This value is measured per JEDEC standard and defines the upper voltage limit imposed on protected circuitry during worst-case transient events.
Can the 1.5KE13CA-E3/54 be used in unidirectional configurations?
No - the "CA" suffix denotes bidirectional construction. Unidirectional variants use "A" suffix (e.g., 1.5KE13A). The 1.5KE13CA-E3/54 has symmetrical VBR and VC in both polarities and lacks a cathode marking; using it in a unidirectional topology would violate its design intent and compromise protection efficacy.
