Product details
Overview
1.5KE100A-E3/54 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 95.0 V to 105 V breakdown voltage (VBR), 85.5 V maximum standoff voltage (VWM), 137 V clamping voltage at 10.9 A peak pulse current, 1500 W peak pulse power rating with 10/1000 µs waveform, and operates across -55 °C to +175 °C junction temperature range - deployed in automotive power supply inputs and industrial sensor interface protection.
For engineers reviewing the 1.5KE100A-E3/54 datasheet, 1.5KE100A-E3/54 pinout, 1.5KE100A-E3/54 application, or 1.5KE100A-E3/54 equivalent, this page delivers verified electrical parameters, JEDEC 1.5KE package details, clamping performance under surge conditions, thermal resistance data (RθJA = 75 °C/W), and direct alternatives for circuit-level ESD and lightning transient hardening.
Technical Context
This unidirectional TVS diode uses a glass-passivated silicon junction optimized for fast response (<1 ns) and low incremental surge resistance. Its clamping action begins at VBR = 95.0–105 V (tested at IT = 1.0 mA), limits transients to VC = 137 V at IPPM = 10.9 A, and sustains 1500 W non-repetitive pulse power per 10/1000 µs waveform per JEDEC standards.
Thermal design is supported by RθJL = 15.4 °C/W (junction-to-lead) and derating curves enabling operation up to TJ = 175 °C. The device complies with JESD 22-B106 (solder dip 275 °C/10 s) and JESD 201 Class 1A whisker testing (E3 suffix), confirming suitability for automated assembly in high-reliability industrial and automotive PCBs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 95.0 V / 105 V - ensures reliable conduction onset above normal 85.5 V DC rail; avoids false triggering during line tolerance variations |
| VWM | 85.5 V - maximum continuous reverse operating voltage; sets safe margin below VBR for 12 V–48 V systems |
| VC @ IPPM | 137 V - clamped voltage at 10.9 A peak pulse; defines worst-case stress on downstream ICs during 10/1000 µs surge |
| PPPM | 1500 W - peak pulse power handling per standard 10/1000 µs waveform; supports IEC 61000-4-5 Level 4 immunity |
| IPPM | 10.9 A - maximum non-repetitive surge current; determines minimum series impedance needed for coordination |
| RθJA | 75 °C/W - junction-to-ambient thermal resistance; informs heatsinking requirements for sustained surge duty cycles |
| TJ max. | +175 °C - maximum junction temperature; enables use in under-hood automotive or high-ambient industrial enclosures |

Applications
| Automotive Power Input Protection | Industrial Sensor Signal Line Protection |
|---|---|
Use Scenario: Protecting 24 V battery-fed ECUs against load dump (ISO 16750-2) and alternator switching transients. IC Role / Device Role / Timing Role: Unidirectional TVS placed between battery rail and DC-DC converter input; clamps surges within 1 ns to limit stress on upstream FETs and regulators. Use Value: Withstands 1500 W pulses while holding clamped voltage ≤137 V - prevents latch-up or gate oxide rupture in 36 V-rated power management ICs. | Use Scenario: Shielding 4–20 mA current-loop sensor outputs from ESD events and induced lightning surges on long field wiring. IC Role / Device Role / Timing Role: TVS mounted at connector entry point, cathode to signal line and anode to local ground; shunts >8 kV HBM ESD and 1 kV/50 Ω surge waveforms. Use Value: Low leakage (<1 µA at 85.5 V) preserves loop accuracy; fast response avoids signal distortion during transient suppression. |
| Telecom DC Power Feeds | Consumer Equipment AC/DC Adapter Outputs |
Use Scenario: Safeguarding PoE-powered devices (e.g., IP cameras, access points) against surges entering via 48 V DC feed lines. IC Role / Device Role / Timing Role: Primary TVS on PSE-side output or PD-side input; coordinated with secondary MOVs and current-limiting resistors. Use Value: 137 V clamping voltage ensures downstream 60 V-rated Ethernet PHYs remain within absolute maximum ratings during 10/1000 µs surges. | Use Scenario: Adding secondary-side surge protection to offline SMPS outputs (e.g., 12 V/19 V laptop adapters) before USB-C or barrel-jack connectors. IC Role / Device Role / Timing Role: Unidirectional clamp between output rail and chassis ground; absorbs coupling from nearby lightning-induced common-mode noise. Use Value: 85.5 V standoff allows compatibility with 12 V–24 V regulated outputs; 175 °C max junction temperature supports sealed enclosure thermal profiles. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100A | DO-214AA package (smaller footprint); 100 V VBR min (90–111 V); 1000 W PPPM; lower IPPM (11.1 A) | Lower power rating suits space-constrained consumer electronics; less suitable for industrial 1500 W surge compliance | Select SMBJ100A only if board area is constrained and 1000 W surge level suffices per IEC 61000-4-5 Level 3 |
| 1.5KE100CA | Bidirectional variant; same VBR/VC specs but symmetrical clamping; no polarity marking; higher capacitance due to dual-junction structure | Required for AC-coupled or floating signal lines (e.g., RS-485, audio); not usable on polarized DC rails without redesign | Choose 1.5KE100CA only when protecting bidirectional interfaces; unidirectional 1.5KE100A-E3/54 remains optimal for DC power rails |
Compared with SMBJ100A, 1.5KE100A-E3/54 delivers 50 % higher surge power headroom and superior thermal robustness in larger DO-201AD package; versus 1.5KE100CA, it offers lower capacitance and simpler layout for DC applications where polarity is fixed.

FAQ
What is the breakdown voltage tolerance for 1.5KE100A-E3/54?
The 1.5KE100A-E3/54 has a specified breakdown voltage range of 95.0 V to 105 V at test current IT = 1.0 mA, representing a ±5 % tolerance about the nominal 100 V rating. This tight VBR window ensures predictable clamping onset across production lots and temperature extremes, critical for coordinating with downstream overvoltage protection circuits. All units meet this specification per Vishay Document Number 88301 Rev. 09-Aug-2022.
Is 1.5KE100A-E3/54 suitable for automotive applications?
The 1.5KE100A-E3/54 is commercial-grade (E3 suffix) and not AEC-Q101 qualified; however, its 175 °C maximum junction temperature, glass-passivated junction, and robust surge capability make it widely used in non-safety-critical automotive subsystems such as infotainment power supplies and body control modules. For AEC-Q101-compliant designs, specify the HE3 variant (e.g., 1.5KE100AHE3_B). The 1.5KE100A-E3/54 itself meets JESD 201 Class 1A whisker testing and solder dip requirements per JESD 22-B106.
How does the clamping voltage of 1.5KE100A-E3/54 compare to its breakdown voltage?
The 1.5KE100A-E3/54 clamps transients to 137 V at its rated peak pulse current of 10.9 A (10/1000 µs waveform), which is 32–42 V above its 95.0–105 V breakdown voltage range. This 35–40 % overvoltage margin reflects the device's incremental surge resistance and ensures downstream components see controlled stress during surge events. The relationship is fixed per JEDEC test conditions and documented in Vishay's 88301 datasheet.
Can 1.5KE100A-E3/54 be used in bidirectional signal protection?
No - the 1.5KE100A-E3/54 is strictly unidirectional, with cathode marked by a color band and intended for DC rail protection where polarity is fixed. For bidirectional signal lines (e.g., RS-485, USB D+/D−), the bidirectional variant 1.5KE100CA must be used instead. Using 1.5KE100A-E3/54 on AC or floating signals risks forward conduction during negative half-cycles and failure to suppress negative transients.
What is the thermal resistance of 1.5KE100A-E3/54, and how does it affect layout?
The 1.5KE100A-E3/54 has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W and junction-to-lead resistance (RθJL) of 15.4 °C/W. In PCB layout, this means copper pour area under the cathode/anode leads significantly reduces thermal impedance; for repeated surge events, minimizing trace length and maximizing pad copper improves heat dissipation. Layout guidance is provided in Vishay's 88301 datasheet Figure 5 and thermal derating curves.
