Overview
1.5KE160CAHE3_B/C from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode designed for high-energy surge protection in power and signal lines. It features a 1500 W peak pulse power rating (10/1000 µs), 136 V standoff voltage (VWM), 152–168 V breakdown voltage (VBR), clamping voltage of 219 V at 6.8 A peak pulse current, and operates across –55 °C to +175 °C junction temperature. It is used to protect MOSFETs, ICs, and sensor interfaces in industrial power supplies and automotive ECUs.
For engineers reviewing the 1.5KE160CAHE3_B/C datasheet, 1.5KE160CAHE3_B/C pinout, 1.5KE160CAHE3_B/C application, or 1.5KE160CAHE3_B/C equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, clamping performance under standardized transients, thermal resistance data, and RoHS-compliant packaging details - all critical for ESD/surge protection design validation and BOM selection.
Technical Context
This device implements a glass-passivated silicon junction optimized for fast transient response (<1 ns) and low incremental surge resistance. Its bidirectional architecture enables symmetrical clamping in AC-coupled or floating signal paths without polarity concerns, and it complies with IEC 61000-4-2 (ESD) and IEC 61000-4-5 (surge) immunity requirements when applied per layout guidelines.
The 1.5KE160CAHE3_B/C uses a DO-201AD (Case Style 1.5KE) package with matte tin-plated leads, rated for solder dip up to 275 °C for 10 s, and meets JESD 201 Class 2 whisker resistance. It is AEC-Q101 qualified per note (2) in the datasheet, covering the full 1.5KE6.8CAHE3_B to 1.5KE220CAHE3_B range - confirming its suitability for automotive electronics.

Applications
| Automotive Power Distribution | Industrial Sensor Signal Lines |
|---|---|
Use Scenario: Protection of 12 V/24 V power rails in engine control units against load-dump transients (ISO 7637-2 Pulse 5a). IC Role / Device Role / Timing Role: Bidirectional TVS placed across input rail to clamp surges >100 V within nanoseconds. Use Value: Prevents latch-up or permanent damage to microcontrollers and power management ICs during battery disconnect events. |
Use Scenario: Shielding analog outputs (e.g., 4–20 mA current loops) in factory automation sensors from EFT and surge coupling. IC Role / Device Role / Timing Role: Low-capacitance TVS connected between signal line and ground to divert fast transients without distorting DC accuracy. Use Value: Maintains signal integrity while meeting IEC 61000-4-4 (EFT) and IEC 61000-4-5 (surge) immunity requirements. |
| Telecom Line Interface | Consumer Power Adapter Input |
Use Scenario: Surge suppression on POTS or DSL line interfaces exposed to lightning-induced surges on outdoor wiring. IC Role / Device Role / Timing Role: Primary-level TVS in series with gas discharge tube (GDT) for staged protection of line drivers and codec ICs. Use Value: Absorbs initial 1500 W energy spike, allowing GDT to handle follow-on current - extending overall system survivability. |
Use Scenario: Input-stage protection in universal-input AC/DC adapters subjected to mains-borne surges per IEC 61000-4-5 Level 3. IC Role / Device Role / Timing Role: Bidirectional TVS across bridge rectifier output to clamp differential-mode surges before bulk capacitor. Use Value: Eliminates need for additional MOVs or varistors, reducing component count while maintaining 136 V working voltage margin. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160CA | Lower peak pulse power (600 W), smaller SMB package (vs. DO-201AD), higher thermal resistance (RθJA = 110 °C/W) | Suitable for space-constrained consumer designs with lower surge threat levels; not AEC-Q101 qualified | Select when board area is limited and surge energy remains below 600 W; verify thermal derating in enclosed enclosures |
| 1.5SMC160CA | Same 1500 W rating and DO-214AB package, but non-AEC-Q101 commercial grade; slightly higher VC (225 V vs. 219 V) | Acceptable for industrial controls where automotive qualification is not required; identical footprint to 1.5KE but different lead form | Choose for cost-sensitive industrial BOMs where AEC-Q101 is unnecessary and lead-form compatibility permits substitution |
Compared with SMBJ160CA and 1.5SMC160CA, the 1.5KE160CAHE3_B/C uniquely combines AEC-Q101 qualification, DO-201AD mechanical robustness, lowest clamping voltage in its class, and proven performance in high-temperature automotive environments - making it the preferred choice for mission-critical vehicle subsystems.

FAQ
What is the clamping voltage of the 1.5KE160CAHE3_B/C at its rated peak pulse current?
The 1.5KE160CAHE3_B/C has a maximum clamping voltage (VC) of 219 V at 6.8 A peak pulse current (IPPM) under 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 worst-case transient event. The 1.5KE160CAHE3_B/C maintains this clamping performance across its full operating temperature range.
Is the 1.5KE160CAHE3_B/C AEC-Q101 qualified?
Yes, the 1.5KE160CAHE3_B/C is explicitly AEC-Q101 qualified per Note (2) in Vishay Document Number 88301, which confirms qualification for the entire 1.5KE6.8CAHE3_B to 1.5KE220CAHE3_B family. This includes testing for temperature cycling, high-temperature reverse bias, and mechanical shock - validating its use in automotive powertrain and body electronics.
What package type does the 1.5KE160CAHE3_B/C use, and what are its key mechanical properties?
The 1.5KE160CAHE3_B/C uses the DO-201AD package (Case Style 1.5KE), featuring a molded epoxy body rated UL 94 V-0, matte tin-plated leads compliant with J-STD-002, and a lead length of 0.375" (9.5 mm). Its thermal resistance from junction to lead is 15.4 °C/W, supporting efficient heat transfer to PCB copper or chassis mounts - critical for sustained surge handling.
How does the bidirectional configuration of the 1.5KE160CAHE3_B/C affect its circuit implementation?
The 1.5KE160CAHE3_B/C has no polarity marking and conducts identically in both directions, enabling direct placement across AC-coupled lines, transformer secondaries, or floating sensor interfaces without orientation checks. This eliminates risk of incorrect installation and simplifies layout in differential or isolated systems - unlike unidirectional variants that require cathode alignment relative to ground.
What is the standoff voltage (VWM) of the 1.5KE160CAHE3_B/C, and why is it important for system design?
The 1.5KE160CAHE3_B/C has a maximum working peak reverse voltage (VWM) of 136 V, meaning it remains non-conductive under normal operation up to this level. This parameter establishes the safe operating margin above nominal system voltage (e.g., 24 V automotive or 110 VAC-derived rails) and ensures no leakage current or power loss during steady-state - essential for low-power and high-efficiency designs.
