Product details
Overview
1.5KE13A-E3/1 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection of DC power rails and signal lines. It features a 12.4 V minimum breakdown voltage (VBR), 11.1 V maximum standoff voltage (VWM), 18.2 V clamping voltage (VC) at 82.4 A peak pulse current, 1500 W peak pulse power rating (10/1000 µs), and operates across –55 °C to +175 °C junction temperature range - used in automotive power supply input stages and industrial sensor interface protection.
For engineers reviewing the 1.5KE13A-E3/1 datasheet, 1.5KE13A-E3/1 pinout, 1.5KE13A-E3/1 application, or 1.5KE13A-E3/1 equivalent, this page delivers verified electrical parameters, package dimensions, clamping behavior under surge conditions, thermal resistance data (RθJA = 75 °C/W), and direct alternatives with documented differences in breakdown tolerance and leakage performance.
Technical Context
This unidirectional TVS diode uses a glass-passivated silicon junction optimized for fast transient suppression (<1 ns response time) and low incremental surge resistance. Its 1500 W peak pulse power rating is defined per 10/1000 µs waveform with 0.01% duty cycle, and it maintains stable clamping up to 175 °C junction temperature.
The device complies with JEDEC standards for transient suppressors and meets UL 94 V-0 flammability requirements. Its matte tin-plated leads are solderable per J-STD-002 and JESD 22-B102, and the E3 suffix confirms RoHS compliance and JESD 201 Class 1A whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 12.4 V / 13.7 V at 1.0 mA test current - defines reliable conduction onset under overvoltage stress |
| VWM | 11.1 V maximum - ensures no conduction during normal 12 V rail operation with margin |
| VC @ IPPM | 18.2 V at 82.4 A - limits downstream IC voltage exposure during 10/1000 µs surge |
| PPPM | 1500 W - sustains single-pulse transients typical of ISO 7637-2 Load Dump or IEC 61000-4-5 Level 4 |
| IFSM | 200 A (8.3 ms half-sine) - handles repetitive inrush or switching surges without degradation |
| TJ range | –55 °C to +175 °C - supports under-hood automotive and industrial ambient environments |
| RθJA | 75 °C/W - enables thermal design with minimal heatsinking for PCB-mounted protection |
Pinout & Package
Package: Case Style 1.5KE - molded epoxy body with axial leads, UL 94 V-0 rated, 0.375" (9.5 mm) lead length, 0.042" (1.07 mm) lead diameter. Dimensions comply with JEDEC TO-204AA outline.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward conduction | Connected to protected line side; cathode tied to ground or return path for clamping |
| Cathode | Current exit point during reverse-biased clamping | Marked by color band; serves as reference node for voltage clamping action |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Enables stable VBR tolerance (±5%) and long-term reliability under thermal cycling |
| 1500 W peak pulse power (10/1000 µs) | Protects against high-energy transients including automotive load dump and inductive switch-off spikes |
| Clamping voltage ≤18.2 V at 82.4 A | Keeps downstream 12 V logic or microcontroller I/O within safe operating area during surge |
| Response time <1 ns | Acts before sensitive components experience damaging overvoltage - faster than MOVs or GDTs |
| RoHS-compliant E3 suffix | Meets JESD 201 Class 1A whisker resistance and global environmental compliance requirements |
Applications
| Automotive Power Input Protection | Industrial Sensor Signal Line Protection |
|---|---|
Use Scenario: 12 V battery-fed ECUs exposed to ISO 7637-2 Pulse 5a (load dump) up to 60 V/100 ms. IC Role / Device Role / Timing Role: Primary shunt clamp on main power rail, activated within <1 ns to divert surge energy to chassis ground. Use Value: Limits rail voltage to ≤18.2 V during 82.4 A transient, preventing damage to LDOs, CAN transceivers, and MCU power domains. |
Use Scenario: 4–20 mA current loop inputs in PLC analog modules subjected to field wiring ESD and inductive kickback. IC Role / Device Role / Timing Role: Unidirectional TVS placed between signal line and ground, clamping positive transients only. Use Value: Maintains signal integrity below 11.1 V standby while suppressing >1 kV transients without affecting loop accuracy. |
| Consumer Power Adapter Output Protection | Telecom DC Feeder Line Protection |
Use Scenario: Secondary-side 12 V output of wall adapters driving USB hubs or PoE injectors. IC Role / Device Role / Timing Role: Standoff-rated TVS across output terminals to absorb capacitor discharge and hot-plug surges.

Use Scenario: -48 V DC telecom feeder lines entering remote radio units exposed to lightning-induced surges. IC Role / Device Role / Timing Role: Unidirectional TVS referenced to negative rail, protecting DC-DC converters and monitoring ICs. Use Value: Withstands 1500 W pulses while maintaining ≤1 µA leakage at –48 V, ensuring low standby power loss. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ13A | Same VWM (11.1 V), but tighter VBR tolerance (12.4–13.7 V vs. 12.36–13.64 V); lower RθJA (65 °C/W) | Suitable for space-constrained layouts requiring higher thermal efficiency; identical 1500 W rating | Select when board-level thermal management is critical and tighter VBR distribution improves system margin. |
| ON Semiconductor 1.5SMC13A | Identical VBR/VWM/VC specs, but packaged in SMC (DO-214AB); 20% smaller footprint, higher IPPM (85.5 A) | Preferred for surface-mount designs; not drop-in compatible due to axial-to-SMD package change | Choose for new SMT designs where automated assembly and reduced board area outweigh axial lead compatibility. |
Compared with 1.5KE13A-E3/1, SMAJ13A offers improved thermal dissipation for high-ambient environments, while 1.5SMC13A enables miniaturized SMT implementation - neither is pin-compatible, but both deliver equivalent clamping performance for 12 V system protection.

FAQ
What is the clamping voltage of the 1.5KE13A-E3/1 under maximum surge conditions?
The 1.5KE13A-E3/1 exhibits a maximum clamping voltage (VC) of 18.2 V when subjected to its rated peak pulse current of 82.4 A using the standard 10/1000 µs waveform. This value is measured per JEDEC test conditions and ensures downstream circuitry remains within safe voltage limits during transient events. The 1.5KE13A-E3/1 achieves this clamping performance while maintaining low incremental surge resistance, critical for effective energy diversion.
Is the 1.5KE13A-E3/1 suitable for automotive applications requiring AEC-Q101 qualification?
No - the 1.5KE13A-E3/1 is a commercial-grade part with E3 suffix (RoHS compliant, JESD 201 Class 1A whisker tested). AEC-Q101 qualified variants carry the HE3 suffix (e.g., 1.5KE13AHE3_B). The 1.5KE13A-E3/1 itself is not AEC-Q101 certified, though it shares identical electrical characteristics and construction with qualified versions. For automotive use, specify the HE3 variant to meet qualification requirements.
How does the 1.5KE13A-E3/1 differ from bidirectional TVS diodes like 1.5KE13CA?
The 1.5KE13A-E3/1 is unidirectional and conducts only in reverse bias above VBR, with polarity marked by a cathode band. In contrast, 1.5KE13CA provides symmetrical clamping for AC or bipolar signals, offering equal VBR in both directions. The 1.5KE13A-E3/1 is intended for DC rail protection where only positive transients matter; 1.5KE13CA suits RS-485, audio lines, or AC-coupled interfaces where voltage swings occur in both polarities.
What is the maximum reverse leakage current of the 1.5KE13A-E3/1 at its standoff voltage?
At its maximum standoff voltage (VWM = 11.1 V), the 1.5KE13A-E3/1 guarantees a maximum reverse leakage current (ID) of 5.0 µA at 25 °C. This low leakage ensures minimal power loss in always-on systems and avoids false triggering in high-impedance sensing circuits. Leakage increases with temperature but remains below 50 µA at 125 °C per datasheet derating curves.
Can the 1.5KE13A-E3/1 be used in parallel to increase surge handling capacity?
Yes - multiple 1.5KE13A-E3/1 devices can be paralleled to distribute surge current, provided they are matched for VBR (within ±3%) and mounted with symmetric thermal paths. Mismatched units may cause current hogging and premature failure. Parallel use is documented in Vishay's application notes for scaling beyond 1500 W, but individual 1.5KE13A-E3/1 units must remain within their specified 82.4 A IPPM limit.
