Product details
Overview
1.5KE160HE3/54 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 standoff voltage (VWM), 171–189 V breakdown voltage (VBR), 219 V clamping voltage (VC) at 6.8 A peak pulse current, and 1500 W peak pulse power capability with a 10/1000 µs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial power supplies.
For engineers reviewing the 1.5KE160HE3/54 datasheet, 1.5KE160HE3/54 pinout, 1.5KE160HE3/54 application, or 1.5KE160HE3/54 equivalent, this part delivers verified AEC-Q101 qualification, glass-passivated junction reliability, RoHS-compliant matte tin leads, and JESD 201 Class 2 whisker resistance - critical for automotive-grade ESD and lightning transient suppression where clamping speed (<1 ns) and low incremental surge resistance are mandatory.
Technical Context
This unidirectional TVS diode operates as a voltage-clamped shunt protector: when transient voltage exceeds its breakdown threshold (171–189 V), it avalanches into low-impedance conduction, diverting surge current away from downstream circuitry. Its 1500 W peak pulse rating is defined under standardized 10/1000 µs waveform conditions with 0.01% duty cycle, and thermal performance is characterized by RθJL = 15.4 °C/W and RθJA = 75 °C/W.
The device uses a molded epoxy case (Case Style 1.5KE) with cathode band marking, supports 200 A non-repetitive forward surge current (IFSM), and exhibits VF = 5.0 V at 100 A - confirming suitability for high-current transient events without forward conduction degradation. Its temperature coefficient of VBR is +0.108 %/°C, enabling predictable voltage drift across –55 °C to +175 °C operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 136 V - maximum continuous reverse working voltage before clamping initiates; defines safe DC rail operating margin. |
| VBR min/max | 171 V / 189 V at 1 mA - precise avalanche onset range ensures consistent turn-on behavior across production lots. |
| VC @ IPPM | 219 V at 6.8 A - clamping voltage during full-rated 10/1000 µs surge; determines protected circuit's maximum transient exposure. |
| PPPM | 1500 W - peak pulse power handling per single 10/1000 µs event; enables robust protection against IEC 61000-4-5 Level 4 surges. |
| IFSM | 200 A - non-repetitive forward surge current rating (8.3 ms half-sine); validates survivability during high-energy fault conditions. |
| TJ max | +175 °C - maximum junction temperature; supports operation in under-hood automotive and industrial environments. |
| ID @ VWM | 1.0 µA - reverse leakage at rated standoff voltage; ensures minimal standby power loss in always-on systems. |
Pinout & Package
1.5KE160HE3/54 uses the industry-standard Case Style 1.5KE axial-leaded package: molded epoxy body with cathode band marking on one end, matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards. Lead length is 0.375" (9.5 mm), diameter 0.042" (1.07 mm).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to ground or low-potential node; completes shunt path during reverse-biased avalanche. |
| Cathode | High-side surge input terminal | Marked with color band; connects to protected line (e.g., 12 V rail or CAN bus); conducts surge current to anode during overvoltage. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enables stable, repeatable avalanche characteristics and long-term reliability under repeated surge stress. |
| AEC-Q101 qualified | Validated for automotive applications including engine control units and body electronics requiring zero defect field performance. |

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 | Lower PPPM (600 W), smaller SMB package (surface-mount), lower IFSM (100 A) | Better suited for space-constrained PCBs but insufficient for 1500 W IEC 61000-4-5 Level 4 compliance | Select only if board layout prohibits axial-leaded devices and surge energy is limited to ≤600 W. |
| 1.5KE160A-E3/54 | Same electrical specs and package, but commercial-grade (non-AEC-Q101) and JESD 201 Class 1A whisker rating | Lacks automotive qualification; acceptable for industrial/commercial power supplies without automotive lifecycle requirements | Choose when AEC-Q101 is not mandated and cost optimization is prioritized over extended reliability validation. |
Compared with SMBJ160A and 1.5KE160A-E3/54, the 1.5KE160HE3/54 uniquely combines 1500 W surge capacity, AEC-Q101 qualification, and JESD 201 Class 2 whisker resistance - making it the only option among the three validated for under-hood automotive use with full IEC 61000-4-5 Level 4 immunity.

FAQ
What is the clamping voltage of the 1.5KE160HE3/54 under full-rated surge conditions?
The 1.5KE160HE3/54 has a maximum clamping voltage (VC) of 219 V at 6.8 A peak pulse current (IPPM) using the standard 10/1000 µs waveform. This value is measured per JEDEC test conditions and defines the upper voltage limit imposed on protected circuitry during a full 1500 W transient event. The actual clamping voltage remains stable across temperature due to its +0.108 %/°C VBR temperature coefficient.
Is the 1.5KE160HE3/54 suitable for automotive applications?
Yes, the 1.5KE160HE3/54 is AEC-Q101 qualified and explicitly listed in Vishay's documentation as meeting automotive reliability requirements. Its HE3 suffix denotes RoHS compliance plus AEC-Q101 qualification, and it passes JESD 201 Class 2 whisker testing - making it approved for use in engine control units, body electronics, and ADAS power domains where sustained operation at 175 °C and surge immunity are mandatory.
How does the 1.5KE160HE3/54 differ from the commercial-grade 1.5KE160A-E3/54?
The 1.5KE160HE3/54 differs from 1.5KE160A-E3/54 in three key areas: it carries AEC-Q101 qualification, meets JESD 201 Class 2 (not Class 1A) whisker resistance, and is designated for automotive-grade production. Electrically and dimensionally identical, the HE3 variant undergoes additional stress testing and lot traceability protocols required for automotive deployment - while the E3 version is intended for commercial/industrial use only.
What is the standoff voltage rating for the 1.5KE160HE3/54?
The 1.5KE160HE3/54 has a maximum reverse standoff voltage (VWM) of 136 V. This is the highest DC or continuous AC voltage the device can block without entering avalanche conduction. It provides a safety margin below the 171–189 V breakdown range and ensures no leakage-induced power loss or false triggering in 120 V nominal systems - critical for maintaining signal integrity in always-on monitoring circuits.
Can the 1.5KE160HE3/54 be used in bidirectional configurations?
No, the 1.5KE160HE3/54 is a unidirectional TVS diode and is not rated for bidirectional operation. Bidirectional variants in the 1.5KE family use the "CA" suffix (e.g., 1.5KE160CA) and are only available up to 1.5KE220CA per Vishay's datasheet. Using the 1.5KE160HE3/54 in reverse-biased AC applications would result in forward conduction and potential failure; always verify polarity marking (cathode band) during placement.
