Product details
Overview
1.5KE160A-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 152 V to 168 V breakdown voltage (VBR), 136 V maximum standoff voltage (VWM), 219 V clamping voltage at 6.8 A peak pulse current, 1500 W peak pulse power (10/1000 µs), and operates from –55 °C to +175 °C junction temperature - deployed in automotive power supply input stages and industrial sensor interface protection.
For engineers reviewing the 1.5KE160A-E3/54 datasheet, 1.5KE160A-E3/54 pinout, 1.5KE160A-E3/54 application, or 1.5KE160A-E3/54 equivalent, this page delivers verified electrical parameters, JEDEC 1.5KE package details, thermal resistance (RθJA = 75 °C/W), clamping behavior under surge conditions, and direct alternative part comparisons for ESD and lightning transient suppression design.
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 limits transient voltages before downstream ICs or MOSFETs experience overstress, with a 10/1000 µs waveform rating and derating above 25 °C ambient per Fig. 2.
The device complies with JEDEC standard test methods and supports soldering per J-STD-002 and JESD 22-B102. The E3 suffix confirms RoHS compliance and JESD 201 Class 1A whisker resistance; it is commercial grade only (not AEC-Q101 qualified).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 152 V / 168 V - ensures reliable conduction onset above normal operating rail (e.g., 136 V nominal 120 VAC-derived DC bus) |
| VWM | 136 V - maximum continuous reverse voltage without significant leakage (≤1 µA) |
| VC @ IPPM | 219 V - clamped voltage during 6.8 A 10/1000 µs surge, limiting stress on protected circuitry |
| PPPM | 1500 W - peak transient power handling capability for standardized lightning/surge immunity testing |
| RθJA | 75 °C/W - thermal resistance from junction to ambient, critical for PCB copper area and heatsinking decisions |
| TJ range | –55 °C to +175 °C - enables use in under-hood automotive and high-temp industrial environments |
| IFSM | 200 A - non-repetitive forward surge current rating (8.3 ms half-sine), relevant for fault-current coordination |

Applications
| Automotive Power Input Protection | Industrial PLC Analog Input Protection |
|---|---|
Use Scenario: Protecting 136 V DC power input stage of engine control unit (ECU) against load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Unidirectional TVS placed between battery rail and input filter capacitor to clamp transients before DC-DC converter.

IC Role / Device Role / Timing Role: TVS placed across optocoupler input or MOSFET gate-source to suppress inductive kickback from relay coils and BLDC drivers. Use Value: Fast <1 ns response prevents latch-up in CMOS logic; 219 V clamping protects 200 V-rated gate drivers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160A | DO-214AA package (smaller footprint), 152–168 V VBR, 219 V VC @ 6.5 A, 600 W PPPM | Lower peak power rating; suitable for space-constrained designs with moderate surge exposure | Select when PCB area is limited and surge threat level is ≤IEC 61000-4-5 Level 3 |
| 1.5SMC160A | SMD DO-214AB package, same VBR/VC, 1500 W rating, but higher thermal resistance (RθJA ≈ 100 °C/W) | Requires larger copper pour for thermal management; not axial-leaded | Choose for automated SMT assembly where through-hole mounting is unavailable |
Compared with 1.5KE160A-E3/54, SMBJ160A offers smaller size but reduced surge robustness, while 1.5SMC160A matches power rating but demands more careful thermal layout - both require revalidation of mechanical fit and board-level clamping performance.

FAQ
What is the breakdown voltage range for 1.5KE160A-E3/54?
The 1.5KE160A-E3/54 has a guaranteed breakdown voltage (VBR) range of 152 V to 168 V at 1.0 mA test current, measured per JEDEC standard. This tight tolerance ensures predictable clamping onset across production lots and supports precise coordination with downstream overvoltage protection circuits. The value is confirmed in Vishay document 88301, Table on page 2.
Is 1.5KE160A-E3/54 AEC-Q101 qualified?
No, 1.5KE160A-E3/54 is commercial grade only. AEC-Q101 qualification applies only to variants with HE3 suffix (e.g., 1.5KE160AHE3_B), as explicitly stated in the "Notes" section of Vishay document 88301. The E3/54 variant meets RoHS and JESD 201 Class 1A whisker requirements but lacks automotive qualification testing.
What is the clamping voltage of 1.5KE160A-E3/54 at its rated peak pulse current?
The 1.5KE160A-E3/54 clamps to a maximum of 219 V at its rated peak pulse current of 6.8 A (10/1000 µs waveform), per the Electrical Characteristics table in Vishay document 88301. This value defines the upper voltage limit imposed on protected circuitry during worst-case surge events and is critical for verifying margin against component absolute maximum ratings.
Can 1.5KE160A-E3/54 be used in bidirectional configurations?
No - 1.5KE160A-E3/54 is strictly unidirectional. Bidirectional versions in the 1.5KE family use the "CA" suffix (e.g., 1.5KE160CA), and the datasheet explicitly states that bidirectional types are available only up to 1.5KE220CA. The "A" suffix and absence of "C" confirm unidirectional polarity, with cathode marked by a color band.
What package type does 1.5KE160A-E3/54 use and what are its key mechanical properties?
The 1.5KE160A-E3/54 uses the JEDEC DO-201AD (Case Style 1.5KE) axial-leaded package: molded epoxy body meeting UL 94 V-0 flammability rating, matte tin-plated leads compliant with J-STD-002, and dimensions of 5.3 mm × 5.3 mm × 9.5 mm. Lead finish passes JESD 201 Class 1A whisker testing, and the body withstands solder dip at 275 °C for 10 s.
