Product details
Overview
1.5KE160AHE3_B/C from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 152 V to 168 V breakdown voltage (VBR), 136 V maximum working voltage (VWM), 219 V clamping voltage 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 against lightning-induced surges and inductive switching transients.
For engineers reviewing the 1.5KE160AHE3_B/C datasheet, 1.5KE160AHE3_B/C pinout, 1.5KE160AHE3_B/C application, or 1.5KE160AHE3_B/C equivalent, this part delivers verified AEC-Q101 qualification (per note 2), RoHS-compliant matte tin plating, JESD 201 Class 2 whisker resistance, and UL 94 V-0 molded epoxy packaging - critical for automotive and industrial reliability validation.
Technical Context
This unidirectional TVS diode employs a glass-passivated silicon junction optimized for fast transient response (<1 ns) and low incremental surge resistance. Its clamping behavior is defined by a 10/1000 µs waveform with 0.01% duty cycle, and it maintains stable performance up to 175 °C junction temperature with thermal resistance RθJL = 15.4 °C/W.
The device exhibits a typical forward voltage of 5.0 V at 100 A (per note 3), supports 200 A non-repetitive forward surge current (8.3 ms half-sine), and achieves 219 V clamping at its rated 6.8 A peak pulse current - enabling robust protection without compromising system-level voltage margins.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 152 V / 168 V - defines precise voltage threshold at which clamping initiates under 1 mA test current |
| VWM | 136 V - maximum continuous reverse operating voltage before leakage exceeds 1 µA |
| VC @ IPPM | 219 V at 6.8 A - clamped voltage during full 1500 W transient, limiting stress on downstream components |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160A-E3/52 | DO-214AA package (SMB), lower 600 W PPPM, 136 V VWM, 221 V VC @ 2.7 A | Lower power handling; suited for space-constrained PCBs where 1500 W surge is not required | Select SMBJ160A-E3/52 when board area is limited and peak surge energy remains below 600 W. |
| 1.5KE160A-E3/54 | Same 1.5KE package and electrical specs, but commercial-grade (non-AEC-Q101), no HE3 suffix | Lacks automotive qualification and JESD 201 Class 2 whisker resistance; suitable for industrial/commercial use only | Choose 1.5KE160A-E3/54 for cost-sensitive non-automotive designs where AEC-Q101 is not mandated. |
Compared with 1.5KE160AHE3_B/C, SMBJ160A-E3/52 trades package size and surge capacity for footprint reduction, while 1.5KE160A-E3/54 retains identical protection performance but omits automotive qualification - making the HE3_B/C variant the sole choice for AEC-Q101–compliant vehicle subsystems.

FAQ
What is the breakdown voltage tolerance for 1.5KE160AHE3_B/C?
The 1.5KE160AHE3_B/C has a specified breakdown voltage (VBR) range of 152 V to 168 V at 1 mA test current, corresponding to ±5% tolerance around the nominal 160 V rating. This tight tolerance ensures predictable clamping onset and simplifies system-level margin analysis for overvoltage protection design.
Is 1.5KE160AHE3_B/C suitable for automotive applications?
Yes, 1.5KE160AHE3_B/C is AEC-Q101 qualified per document note (2), covering the full 1.5KE6.8AHE3_B to 1.5KE220AHE3_B range. Its construction includes JESD 201 Class 2 whisker resistance, UL 94 V-0 molding, and operation up to +175 °C - meeting critical requirements for engine control, body electronics, and ADAS power systems.
What is the clamping voltage of 1.5KE160AHE3_B/C at its rated peak pulse current?
The 1.5KE160AHE3_B/C clamps to a maximum of 219 V at its rated peak pulse current of 6.8 A (10/1000 µs waveform). This value is measured per JEDEC standard test conditions and defines the upper voltage limit imposed on protected circuitry during worst-case surge events.
Does 1.5KE160AHE3_B/C have bidirectional capability?
No, 1.5KE160AHE3_B/C is a unidirectional TVS diode. Bidirectional variants in the 1.5KE family use the "CA" suffix (e.g., 1.5KE160CA) and are only available up to 1.5KE220CA per the datasheet note. The "A" suffix and absence of "C" confirm unidirectional polarity for 1.5KE160AHE3_B/C.
What package type does 1.5KE160AHE3_B/C use, and what are its key mechanical properties?
1.5KE160AHE3_B/C uses the DO-201AD (Case Style 1.5KE) axial-leaded package with 0.375" (9.5 mm) lead length.
