Product details
Overview
1.5KE10C-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 10 V standoff voltage (VWM), 14.5 V maximum clamping voltage (VC) at 10.3 A peak pulse current, 1500 W peak pulse power (10/1000 µs), and operates from –55 °C to +175 °C. It protects MOSFETs and ICs in automotive sensor interfaces against ESD and inductive switching surges.
For engineers reviewing the 1.5KE10C-E3/54 datasheet, 1.5KE10C-E3/54 pinout, 1.5KE10C-E3/54 application, or 1.5KE10C-E3/54 equivalent, this page delivers verified electrical parameters, JEDEC-standardized package dimensions, polarity marking conventions, thermal derating behavior, and direct alternative options for circuit protection design-in.
Technical Context
This device uses a glass-passivated silicon junction optimized for fast transient response (<1 ns) and low incremental surge resistance. Its bidirectional structure enables symmetrical clamping in AC-coupled or floating signal paths without polarity sensitivity-unlike unidirectional variants that require cathode orientation.
The 1.5KE10C-E3/54 complies with JEDEC standard 1.5KE case style, supports 0.01% duty cycle repetitive surge events, and exhibits a temperature coefficient of breakdown voltage of +0.073 %/°C-enabling stable clamping across industrial temperature ranges without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 10 V - Maximum continuous reverse voltage before clamping begins; defines safe operating margin below breakdown. |
| VBR (Breakdown Voltage) | 9.5–10.5 V at 1 mA - Tight tolerance ensures predictable turn-on threshold for consistent protection timing. |
| VC (Clamping Voltage) | 14.5 V at 10.3 A (10/1000 µs) - Limits downstream voltage stress during surge; critical for 12 V system compatibility. |
| PPPM (Peak Pulse Power) | 1500 W - Sustains high-energy transients (e.g., ISO 7637-2 Pulse 1/2/5a) without failure. |
| IPPM (Peak Pulse Current) | 10.3 A - Quantifies surge current handling capacity; used with PCB trace width and layout rules. |
| TJmax | +175 °C - Enables placement near hot components (e.g., power MOSFETs, motor drivers) without thermal derating penalties. |
| Package | DO-201AD (Case Style 1.5KE) - Standard axial-leaded through-hole package with 0.375" lead length; compatible with legacy wave-solder processes. |
Pinout & Package
1.5KE10C-E3/54 uses a two-terminal DO-201AD (Case Style 1.5KE) package with no polarity marking-consistent with bidirectional TVS construction. Leads are matte tin-plated, solderable per J-STD-002 and JESD 22-B102, and rated for 275 °C dip soldering (10 s max).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient conduction path | Both terminals function identically; no cathode band-enables blind mounting in AC or floating circuits. |
| Leads (axial) | Thermal and mechanical interface | 0.375" (9.5 mm) lead length provides mechanical strain relief and meets JEDEC thermal resistance target (RθJL = 15.4 °C/W). |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enables stable leakage performance (<1 μA at VWM) over lifetime and humidity exposure. |
| 1500 W peak pulse rating (10/1000 µs) | Meets IEC 61000-4-5 Level 4 (4 kV line-to-line) without series impedance redesign. |
| Sub-nanosecond response time | Clamps transients before sensitive logic or analog inputs experience overvoltage damage. |
| AEC-Q101 qualified option available | HE3 suffix variants support automotive-grade reliability requirements (e.g., engine control, ADAS sensors). |
| UL 497B recognized (QVGQ2) | Validates suitability for telecom and industrial safety-critical surge protection applications. |
Applications
| Automotive Sensor Interface | Industrial CAN Bus Protection |
|---|---|

Use Value: Maintains 10 V VWM margin above nominal 5 V supply while clamping to ≤14.5 V-preserving signal integrity and preventing latch-up in 5 V tolerant receivers. | Use Scenario: Safeguarding CANH/CANL differential pair in factory automation gateways subjected to EFT bursts and cable discharge events. IC Role / Device Role / Timing Role: Low-capacitance (≈100 pF typical) bidirectional TVS placed across bus lines to suppress common-mode surges without distorting 1 Mbps CAN signaling. Use Value: 14.5 V clamping prevents transceiver overvoltage beyond absolute maximum ratings while supporting >10000 surge cycles per MIL-STD-883 Method 3015.7. |
| Consumer Power Adapter Input | Telecom DSL Line Protection |
Use Scenario: Secondary-side transient suppression on 12 V DC output rails of wall adapters subject to lightning-induced surges via connected devices. IC Role / Device Role / Timing Role: Standoff-rated TVS mounted after bulk capacitor to absorb residual spikes not filtered by upstream MOVs or ferrites. Use Value: 1500 W rating handles 10/1000 µs surges up to 10.3 A without degradation-extending adapter field life in lightning-prone regions. | Use Scenario: Primary protection on POTS/DSL line cards where induced surges from nearby power lines threaten ADSL transceivers. IC Role / Device Role / Timing Role: First-stage protector bridging tip/ring lines to ground, coordinated with gas discharge tube (GDT) for staged clamping. Use Value: UL 497B recognition validates compliance with telecom safety standards; 175 °C TJmax supports operation in sealed outdoor cabinets. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10CA | DO-214AA package (SMB), 1000 W PPPM, 17.0 V VC at 8.3 A; lower power, higher clamping voltage. | Suitable for space-constrained PCBs but requires layout revision due to surface-mount footprint and reduced surge margin. | Select when board area is limited and 1000 W surge capability suffices-verify VC margin against downstream IC abs max ratings. |
| 1.5KE10CA | Same DO-201AD package and electrical specs; differs only in packaging suffix (E3/54 = tape-and-reel, CA = base part number without reel code). | No functional or application difference; identical performance and mounting. | Choose 1.5KE10CA for prototype builds or non-automated assembly; 1.5KE10C-E3/54 is preferred for high-volume SMT line feeding. |
Compared with SMBJ10CA, the 1.5KE10C-E3/54 delivers 50% higher surge power and 2.5 V lower clamping-critical for protecting 12 V systems with tight voltage margins. Versus 1.5KE10CA, it offers identical protection performance with optimized logistics for automated placement.

FAQ
What is the clamping voltage of the 1.5KE10C-E3/54 under a 10/1000 µs surge?
The 1.5KE10C-E3/54 clamps to a maximum of 14.5 V at 10.3 A peak pulse current under the standardized 10/1000 µs waveform. This value is guaranteed per Vishay's datasheet (Document Number 88301, Rev. 09-Aug-2022) and reflects worst-case device behavior at TA = 25 °C. Engineers must verify system-level voltage margins using this VC value-not VBR-when designing protection for 12 V rails or 5 V logic interfaces.
Is the 1.5KE10C-E3/54 RoHS compliant and lead-free?
Yes, the 1.5KE10C-E3/54 is RoHS compliant and lead-free. The "E3" suffix explicitly denotes commercial-grade, RoHS-compliant construction per Vishay's ordering nomenclature. Its matte tin-plated leads meet J-STD-002 solderability requirements, and the molding compound satisfies UL 94 V-0 flammability rating-making it suitable for environmentally regulated markets including EU and China RoHS.
Does the 1.5KE10C-E3/54 have polarity markings on the body?
No, the 1.5KE10C-E3/54 has no polarity markings because it is a bidirectional TVS diode. Unlike unidirectional variants (e.g., 1.5KE10A), which feature a cathode band, the "C" suffix indicates symmetrical conduction-both terminals behave identically. This allows blind installation in AC-coupled or floating circuits without orientation verification, reducing assembly errors in high-volume manufacturing.
What is the thermal resistance from junction to lead (RθJL) for the 1.5KE10C-E3/54?
The thermal resistance from junction to lead (RθJL) for the 1.5KE10C-E3/54 is 15.4 °C/W, as specified in Vishay's thermal characteristics table (Document Number 88301, page 3). This value assumes 0.375" (9.5 mm) lead length and is critical for calculating junction temperature rise during repetitive surge events-especially when mounted on PCBs with limited copper pour or in enclosed enclosures.
Can the 1.5KE10C-E3/54 be used in automotive applications?
The base 1.5KE10C-E3/54 is commercial-grade, but AEC-Q101 qualified versions exist under the HE3 suffix (e.g., 1.5KE10CHE3_B). For automotive use, specify the HE3 variant-confirmed in Vishay's datasheet notes (page 3, footnote 2)-which undergoes stress testing per AEC-Q101 including temperature cycling, HTRB, and ESD. The 1.5KE10C-E3/54 itself is not AEC-Q101 certified and should be limited to non-safety-critical or non-automotive applications unless validated per customer-specific qualification protocols.
