Product details
Overview
1.5KE10A/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary-level overvoltage protection in DC power rails and signal lines. It features a 9.5 V minimum breakdown voltage (VBR), 8.55 V maximum standoff voltage (VWM), 14.5 V clamping voltage at 10 A peak pulse current, 1500 W peak pulse power rating (10/1000 µs), and operates across -55 °C to +175 °C junction temperature. It is commonly deployed to protect MOSFET gate drivers and microcontroller I/O pins against ESD and inductive switching transients.
For engineers reviewing the 1.5KE10A/54 datasheet, 1.5KE10A/54 pinout, 1.5KE10A/54 application, or 1.5KE10A/54 equivalent, this page delivers verified electrical parameters, package dimensions, clamping behavior under surge conditions, thermal derating curves, and direct alternative options - all validated against Vishay's official 88301 specification document dated 09-Aug-2022.
Technical Context
The 1.5KE10A/54 uses a glass-passivated silicon junction optimized for fast transient response (<1 ns) and low incremental surge resistance. Its unidirectional polarity enables cathode-referenced clamping on positive-going surges while blocking reverse leakage below 8.55 V.
It complies with JEDEC standard test waveforms (10/1000 µs, 8.3 ms half-sine), supports 200 A non-repetitive forward surge current (IFSM), and exhibits a temperature coefficient of VBR at +0.073 %/°C - enabling predictable voltage shift across automotive-grade operating ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 9.50 V / 10.5 V at 1.0 mA test current - defines precise clamping onset threshold for design margining |
| VWM | 8.55 V maximum - ensures reliable blocking during normal 5 V or 9 V rail operation without leakage-induced power loss |
| VC @ IPPM | 14.5 V at 10 A peak pulse - limits downstream voltage stress to safe levels for 3.3 V/5 V logic interfaces |
| PPPM | 1500 W (10/1000 µs waveform) - sustains high-energy lightning or inductive kick events without failure |
| IFSM | 200 A (8.3 ms half-sine) - withstands motor driver or relay coil turn-off surges without bond wire fusing |
| Junction Temp Range | -55 °C to +175 °C - supports under-hood automotive, industrial motor control, and outdoor telecom deployments |
| Thermal Resistance | RθJL = 15.4 °C/W - enables direct lead-to-heatsink thermal path for sustained power dissipation up to 6.5 W |
Pinout & Package
1.5KE10A/54 is housed in the industry-standard Case Style 1.5KE molded epoxy package (DO-201AD), featuring axial leads with cathode band marking. The device has two terminals: anode and cathode - polarity is critical for unidirectional clamping placement relative to protected circuit ground.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference node for clamping action | Connected to protected line (e.g., 5 V rail); conducts when voltage exceeds VBR toward cathode |
| Cathode | Clamping output terminal | Connected to system ground or lower-potential rail; sinks surge current during overvoltage events |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enables stable VBR tolerance and long-term reliability under humidity and thermal cycling |
| 1500 W peak pulse power | Handles IEC 61000-4-5 Level 4 surges (4 kV, 2 Ω source) without degradation |
| 10 ns response time | Clamps before sensitive ICs experience latch-up or gate oxide rupture |
| Low clamping ratio (VC/VBR ≈ 1.45) | Minimizes overvoltage overshoot during fast transients - critical for 3.3 V logic protection |
| AEC-Q101 qualified option available | HE3 suffix variants meet automotive qualification for engine control and body electronics |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs from load dump and alternator ripple transients. IC Role / Device Role / Timing Role: Primary overvoltage clamp placed between battery input and DC-DC converter input stage. Use Value: Limits input voltage to ≤14.5 V during 100 V/400 ms load dump events, preventing regulator latch-up and capacitor overvoltage. |
Use Scenario: Shielding 4–20 mA current loop transmitters from field wiring ESD and inductive coupling. IC Role / Device Role / Timing Role: Bidirectional clamping not applicable; 1.5KE10A/54 used unidirectionally on supply side of loop-powered sensor. Use Value: Clamps induced surges to <15 V, preserving analog front-end accuracy and avoiding ADC saturation or op-amp rail-to-rail clipping. |
| Consumer USB Port Surge Suppression | Telecom Line Card Transient Protection |
Use Scenario: Adding secondary surge immunity to USB VBUS lines in set-top boxes and docking stations. IC Role / Device Role / Timing Role: Standoff-rated TVS placed upstream of USB power switch to absorb hot-plug spikes and contact bounce. Use Value: Blocks >8.55 V transients while maintaining <1 µA leakage at 5 V - no impact on USB enumeration or power budget. |
Use Scenario: Front-end protection for Ethernet PHY power supplies in DSLAM and ONU line cards. IC Role / Device Role / Timing Role: Unidirectional clamp on +3.3 V or +5 V bias rail feeding magnetics and PHY ICs. Use Value: Withstands repeated 1.5 kV ring wave surges per ITU-T K.21, ensuring >100,000 surge cycles without parameter drift. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10A | Lower PPPM (600 W), smaller SMB package (vs. DO-201AD), same VWM/VC profile | Better suited for space-constrained PCBs; limited to lower-energy surges (IEC 61000-4-5 Level 2) | Select SMBJ10A when board area is constrained and surge energy does not exceed 600 W capability. |
| 1.5KE10CA | Bidirectional variant; identical VBR, VWM, VC, and PPPM, but symmetric clamping in both polarities | Required for AC-coupled lines or floating references where negative transients occur (e.g., RS-485, CAN bus) | Choose 1.5KE10CA only when bidirectional clamping is mandated by signal polarity or interface standard. |
Compared with SMBJ10A and 1.5KE10CA, the 1.5KE10A/54 offers higher surge robustness in a through-hole package ideal for high-reliability power entry points, while retaining compatibility with legacy DO-201AD footprints and automated axial tape-and-reel assembly (54 mm reel pitch).

FAQ
What is the exact breakdown voltage range for 1.5KE10A/54?
The 1.5KE10A/54 has a guaranteed breakdown voltage (VBR) range of 9.50 V to 10.5 V at 1.0 mA test current, per Vishay Document Number 88301. This tight tolerance ensures consistent clamping onset across production lots and supports robust design margining for 5 V or 9 V systems. The 1.5KE10A/54 achieves this via precision diffusion and glass passivation of the silicon junction.
Does 1.5KE10A/54 support automotive qualification?
The base 1.5KE10A/54 is commercial-grade; however, the AEC-Q101 qualified version is available as 1.5KE10AHE3_B (with HE3 suffix and revision code B). This variant meets stress testing requirements for temperature cycling, humidity, and mechanical shock per AEC-Q101 Rev D, making it suitable for engine control, body electronics, and ADAS power domains. The 1.5KE10A/54 itself is not AEC-Q101 certified.
What is the maximum clamping voltage of 1.5KE10A/54 under surge conditions?
The 1.5KE10A/54 clamps to a maximum of 14.5 V at 10 A peak pulse current (IPPM) using the standardized 10/1000 µs waveform. This value is measured per JEDEC test method and reflects worst-case voltage seen by downstream components during surge events. The 1.5KE10A/54 maintains this clamping performance across its full operating temperature range (-55 °C to +175 °C).
Can 1.5KE10A/54 be used in bidirectional protection circuits?
No - the 1.5KE10A/54 is strictly unidirectional and must be oriented with its cathode band toward ground to function correctly. For bidirectional protection, the designated part is 1.5KE10CA, which provides symmetrical clamping for both positive and negative transients. Using 1.5KE10A/54 in a bidirectional configuration would result in forward conduction and potential failure during negative excursions.
What package type and lead finish does 1.5KE10A/54 use?
The 1.5KE10A/54 uses the DO-201AD (Case Style 1.5KE) axial-leaded package with matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards. The molding compound meets UL 94 V-0 flammability rating, and the E3 suffix indicates RoHS compliance and JESD 201 Class 1A whisker resistance. The 1.5KE10A/54 is supplied on 13" paper tape reels with 1400 units per reel (54 mm pitch).
