Product details
Overview
1.5KE160-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for high-energy surge protection in DC power rails and signal lines. It features a 160 V breakdown voltage (VBR = 152–168 V), 136 V maximum working voltage (VWM), 219 V clamping voltage (VC) at 6.8 A peak pulse current, 1500 W peak pulse power (10/1000 µs), and operates across –55 °C to +175 °C junction temperature. It is used to protect MOSFETs, ICs, and sensor interfaces in industrial power supplies.
For engineers reviewing the 1.5KE160-E3/54 datasheet, 1.5KE160-E3/54 pinout, 1.5KE160-E3/54 application, or 1.5KE160-E3/54 equivalent, this page delivers verified electrical parameters, JEDEC 1.5KE package details, clamping behavior under transient stress, thermal derating curves, and RoHS-compliant commercial-grade sourcing context - all specific to the 1.5KE160-E3/54 variant.
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 overvoltage before sensitive downstream components experience destructive stress, with VC = 219 V at IPPM = 6.8 A under standardized 10/1000 µs waveform conditions.
It is rated for 1500 W non-repetitive peak pulse power, 6.5 W steady-state power dissipation on infinite heatsink at TL = 75 °C, and supports 200 A forward surge current (8.3 ms half-sine). Thermal resistance is RθJA = 75 °C/W and RθJL = 15.4 °C/W, confirming suitability for lead-mounted PCB-level protection without active cooling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 152 V / 168 V - Ensures reliable conduction onset above normal operating voltage while avoiding false triggering. |
| VWM | 136 V - Maximum continuous reverse voltage the device blocks without significant leakage (≤1 µA). |
| VC @ IPPM | 219 V at 6.8 A - Clamped voltage during 10/1000 µs surge; defines upper voltage limit seen by protected circuitry. |
| PPPM | 1500 W - Peak transient energy absorption capability, enabling robust protection against lightning-induced surges. |
| IFSM | 200 A - Withstands 8.3 ms half-sine surge without failure, supporting high-energy fault events in power systems. |
| TJ range | –55 °C to +175 °C - Enables deployment in under-hood automotive, industrial motor drives, and outdoor telecom equipment. |
| Package | JEDEC DO-201AD (Case Style 1.5KE) - Axial-leaded, epoxy-molded package with matte tin-plated leads compliant to J-STD-002. |
Pinout & Package
1.5KE160-E3/54 is housed in a DO-201AD axial package (Case Style 1.5KE), with cathode indicated by a color band on one end. The device has two terminals: anode and cathode. No internal circuitry or multi-pin configuration - it functions as a two-terminal bidirectional-capable (unidirectional variant) surge clamp.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point in forward bias; connected to ground or low-side reference in unidirectional TVS configuration. | Completes clamping path when transient exceeds VBR; must be routed with low-inductance trace to minimize overshoot. |
| Cathode | Current exit point in forward bias; marked with color band; connected to protected line (e.g., 136 V rail). | Defines polarity-sensitive placement - reversal prevents clamping and risks catastrophic failure under overvoltage. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enables stable VBR tolerance (±5 %), low leakage (<1 µA at VWM), and long-term reliability under thermal cycling. |
| 1500 W peak pulse power (10/1000 µs) | Supports IEC 61000-4-5 Level 4 surge immunity (4 kV line-to-earth) in single-stage protection designs. |
| Clamping voltage ≤219 V at 6.8 A | Provides margin below 250 V absolute maximum ratings of common 200 V-class MOSFETs and gate drivers. |
| RoHS-compliant E3 suffix | Meets JESD 201 Class 1A whisker resistance and UL 94 V-0 flammability - suitable for commercial and industrial PCB assembly. |
| Fast response time <1 ns | Activates before induced transients propagate through PCB traces, limiting voltage rise rate (dV/dt) at protected node. |
Applications
| Industrial Motor Drives | Telecom Power Feeds |

IC Role / Device Role / Timing Role: Secondary clamping stage after polyfuse or PTC, placed directly at power entry to suppress residual overshoot beyond primary TVS array. Use Value: Withstands 200 A 8.3 ms surge and clamps to 219 V, ensuring microcontroller and CAN transceiver survival during 35 V/100 ms load dump events. |
Use Scenario: Overvoltage safeguard on primary-side rectified output (e.g., ~136 V DC) of universal-input SMPS in washing machines and HVAC controllers. IC Role / Device Role / Timing Role: Standoff protector across bulk capacitor to prevent catastrophic failure during MOV degradation or rectifier short-circuit faults. Use Value: Maintains <1 µA leakage at 136 V, avoids standby power penalty, and triggers only during >152 V transients - minimizing false trips. |
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; lower PPPM = 600 W; VC = 259 V @ 2.3 A; smaller footprint but lower surge capacity. | Preferred for space-constrained consumer electronics where 600 W suffices; unsuitable for industrial 1500 W requirements. | Select SMBJ160A only if board area is critical and surge threat level is limited to IEC 61000-4-5 Level 2 (1 kV differential). |
| 1.5KE150A | Lower VBR (143–158 V); VWM = 128 V; VC = 207 V @ 7.2 A; identical package and PPPM. | Used where system nominal voltage is ≤120 V DC and tighter clamping margin below 207 V is required. | Choose 1.5KE150A instead of 1.5KE160-E3/54 only when design requires lower standoff voltage and confirmed compatibility with 128 V max operating rail. |
Compared with 1.5KE160-E3/54, SMBJ160A trades surge capacity for compactness, while 1.5KE150A offers lower clamping at reduced standoff - neither is pin-compatible nor drop-in; both require layout and system-level validation for voltage margin and energy handling.

FAQ
What is the breakdown voltage range for 1.5KE160-E3/54?
The 1.5KE160-E3/54 has a guaranteed breakdown voltage (VBR) range of 152 V to 168 V at test current IT = 1.0 mA. This tolerance ensures consistent clamping onset across production lots while maintaining sufficient margin above its 136 V maximum working voltage (VWM). The specification is validated per JEDEC standards and applies at TA = 25 °C.
Is 1.5KE160-E3/54 RoHS compliant and qualified for automotive use?
Yes, the 1.5KE160-E3/54 carries the E3 suffix, indicating RoHS compliance per EU Directive 2011/65/EU and JESD 201 Class 1A whisker resistance. However, it is commercial grade only - AEC-Q101 qualification applies only to HE3-suffix variants (e.g., 1.5KE160AHE3_B). For automotive applications requiring AEC-Q101, specify the HE3 version, not 1.5KE160-E3/54.
What is the clamping voltage of 1.5KE160-E3/54 under surge conditions?
The 1.5KE160-E3/54 clamps to a maximum of 219 V when subjected to its rated peak pulse current of 6.8 A under the standard 10/1000 µs waveform. This VC value defines the upper voltage limit imposed on protected circuitry during transient events and is measured per ANSI/IEEE C62.35 with strict thermal preconditioning.
Can 1.5KE160-E3/54 be used in bidirectional configurations?
No - 1.5KE160-E3/54 is a unidirectional TVS diode, identified by the "A" suffix. Bidirectional variants use the "CA" suffix (e.g., 1.5KE160CA). Using 1.5KE160-E3/54 in AC or floating applications will result in forward conduction during negative half-cycles and potential failure. Always match suffix to system polarity requirements.
What is the thermal resistance and maximum junction temperature of 1.5KE160-E3/54?
The 1.5KE160-E3/54 has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W and junction-to-lead (RθJL) of 15.4 °C/W. Its maximum operating junction temperature is +175 °C, with storage range from –55 °C to +175 °C. Derating begins above TA = 25 °C per Figure 2 in Vishay document 88301.
