Product details
Overview
1.5KE13C-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 waveform), and clamps to ≤18.2 V at 82.4 A peak pulse current - used in automotive sensor interfaces, industrial I/O protection, and telecom line surge suppression.
For engineers reviewing the 1.5KE13C-E3/54 datasheet, 1.5KE13C-E3/54 pinout, 1.5KE13C-E3/54 application, or 1.5KE13C-E3/54 equivalent, this page delivers verified electrical parameters, package dimensions, clamping behavior under surge conditions, thermal derating curves, and direct alternative options for ESD/lightning transient protection design.
Technical Context
This device operates as a silicon avalanche diode with glass-passivated junction, delivering bidirectional clamping action - symmetric conduction in both polarities without polarity marking. Its 10/1000 µs waveform response enables sub-nanosecond clamping onset, and low incremental surge resistance ensures minimal voltage overshoot during fast transients.
Designed for unmounted leaded operation, it uses Case Style 1.5KE (DO-201AD) with matte tin-plated leads compliant to J-STD-002 and JESD 22-B102. Thermal resistance is RθJA = 75 °C/W and RθJL = 15.4 °C/W, supporting reliable operation up to TJ = +175 °C.
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 surge events |
| VWM | 11.1 V - maximum continuous reverse working voltage before leakage exceeds 5 µA |
| VC @ IPPM | ≤18.2 V at 82.4 A - actual clamped voltage seen by protected circuit during 1500 W transient |
| PPPM | 1500 W - peak pulse power handling capability per 10/1000 µs standard lightning surge waveform |
| IFSM | Not applicable - bidirectional device has no forward surge rating (unidirectional only) |
| TJ range | –55 °C to +175 °C - supports operation in under-hood automotive and industrial ambient environments |
| Capacitance | Not specified in datasheet - not characterized for high-frequency signal line use (e.g., USB, HDMI) |
Pinout & Package
1.5KE13C-E3/54 uses the DO-201AD (Case Style 1.5KE) axial-leaded package: molded epoxy body, 0.375" (9.5 mm) lead length, 0.210" (5.3 mm) body diameter, matte tin-plated leads. No polarity marking - symmetric bidirectional terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional avalanche junction | Either terminal serves as cathode or anode depending on transient polarity - no color band or marking required |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Enables stable, repeatable avalanche breakdown with low parameter drift over temperature and life |
| 1500 W peak pulse power (10/1000 µs) | Withstands IEC 61000-4-5 Level 4 surges (4 kV line-earth, 2 kV line-line) without degradation |
| Sub-nanosecond response time | Clamps transients before sensitive ICs experience overvoltage stress - critical for MOSFET gate and microcontroller I/O protection |
| AEC-Q101 qualified option available | HE3 suffix variants meet automotive reliability requirements (e.g., 1.5KE13CAHE3_B), though 1.5KE13C-E3/54 is commercial grade |
| UL 497B recognized (QVGQ2) | Approved for use in telecom and industrial communication line protectors per Underwriters Laboratories |
Applications
| Automotive Sensor Interface | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting CAN/LIN bus nodes and analog sensor inputs (e.g., pressure, temperature) from load dump and inductive switching spikes in vehicle ECUs. IC Role / Device Role / Timing Role: Bidirectional clamping element placed across differential or single-ended signal lines upstream of interface ICs. Use Value: Limits transient voltage to ≤18.2 V, preventing latch-up or gate oxide damage in 12 V automotive systems. | Use Scenario: Shielding digital input modules in programmable logic controllers from field-wiring induced surges (e.g., relay coil kickback, motor noise). IC Role / Device Role / Timing Role: Primary surge shunt device mounted at connector entry point, diverting energy to ground before reaching isolation barrier or MCU GPIO. Use Value: Handles repetitive 1500 W pulses at 0.01% duty cycle - sustains long-term reliability in factory automation environments. |
| Telecom Line Interface | Power Supply Input Stage |
Use Scenario: Secondary protection on POTS, DSL, or RS-485 lines exposed to lightning-induced surges in outdoor telecom cabinets. IC Role / Device Role / Timing Role: Coordinated clamping stage downstream of gas discharge tube (GDT) primary protector. Use Value: Fast response complements slower GDTs; clamps residual let-through voltage to safe levels for line transceivers. | Use Scenario: Input-stage transient suppression on 12–24 V DC power rails feeding industrial embedded systems or PoE-powered devices. IC Role / Device Role / Timing Role: Parallel-connected TVS across bulk input capacitor to clamp switch-mode supply turn-on spikes and external surge coupling. Use Value: Withstands 82.4 A peak pulse without failure - prevents overvoltage shutdown or regulator damage during brownout recovery. |
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 | DO-214AA (SMB) package, 13 V VBR, 600 W PPPM, lower IPPM (32.9 A) | Surface-mount only; unsuitable for through-hole legacy designs or high-power discrete layouts | Select when board space is constrained and 600 W surge rating suffices - requires PCB rework for footprint change |
| 1.5KE13CA | Same DO-201AD package, identical VBR/VC/PPPM, but E3/54 denotes tape-and-reel packaging (1400 pcs/reel); base 1.5KE13CA may be bulk or different reel size | No functional difference - same electrical and thermal performance; only packaging and ordering code differs | Direct form-fit-function replacement if sourcing flexibility or alternate reel configuration is needed |
Compared with 1.5KE13C-E3/54, SMBJ13CA trades 60% lower surge capacity for SMT compatibility, while 1.5KE13CA matches all electrical and mechanical specs - differing only in packaging logistics and orderable part number format.

FAQ
What is the breakdown voltage tolerance for 1.5KE13C-E3/54?
The 1.5KE13C-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 predictable clamping onset across production lots and temperature extremes, critical for coordinating with downstream overvoltage protection thresholds in 12 V systems.
Is 1.5KE13C-E3/54 RoHS compliant and halogen-free?
Yes, the "E3" suffix in 1.5KE13C-E3/54 confirms RoHS compliance per EU Directive 2011/65/EU and Vishay's material declaration Doc. 99912. The device uses halogen-free molding compound meeting IEC 61249-2-21, and matte tin-plated leads satisfy JESD 201 Class 1A whisker resistance requirements.
Does 1.5KE13C-E3/54 have AEC-Q101 qualification?
No - 1.5KE13C-E3/54 is commercial-grade. AEC-Q101 qualified versions carry the "HE3" suffix (e.g., 1.5KE13CAHE3_B). The "E3/54" designation indicates RoHS-compliant commercial packaging in 13" paper tape (1400 pcs/reel), not automotive qualification.
What is the maximum clamping voltage of 1.5KE13C-E3/54 at rated peak pulse current?
The maximum clamping voltage (VC) for 1.5KE13C-E3/54 is 18.2 V at 82.4 A peak pulse current (IPPM), measured under the standardized 10/1000 µs waveform. This value defines the worst-case voltage imposed on protected circuitry during a full-rated 1500 W transient event.
Can 1.5KE13C-E3/54 be used in parallel for higher surge current handling?
Yes - the 1.5KE13C-E3/54 can be paralleled to increase total surge current capacity, provided matched units are used and layout minimizes current imbalance (e.g., symmetrical trace lengths, shared thermal plane). Derating per Vishay Fig. 2 applies: at TA = 75 °C, PD drops to ~4.5 W, affecting sustained dissipation but not single-pulse capability.
