Product details
Overview
1.5KE160CHE3/73 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 160 V breakdown voltage (VBR = 152–168 V), 136 V maximum working voltage (VWM), 219 V clamping voltage at 6.8 A peak pulse current, and 1500 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive power supplies, industrial motor controllers, and telecom interface protection.
For engineers reviewing the 1.5KE160CHE3/73 datasheet, 1.5KE160CHE3/73 pinout, 1.5KE160CHE3/73 application, or 1.5KE160CHE3/73 equivalent, this page delivers verified electrical parameters, JEDEC-standard 1.5KE package details, AEC-Q101 qualification status, thermal resistance (RθJA = 75 °C/W), and real-world clamping behavior under transient surge conditions.
Technical Context
This TVS diode uses a glass-passivated silicon junction optimized for fast response (<1 ns) and low incremental surge resistance. Its unidirectional polarity enables cathode-referenced clamping on positive transients, with VF = 5.0 V at 100 A forward surge - critical for protecting downstream MOSFET gates and IC power inputs.
Rated for TJ = –55 °C to +175 °C operation and compliant with JESD 22-B106 (275 °C solder dip), the device supports high-reliability deployment in under-hood automotive modules and industrial PLC I/O stages where sustained thermal stress and repetitive ESD/lightning surges occur.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 152 V / 168 V - ensures reliable conduction onset above normal 136 V DC rail, preventing false triggering during line tolerance excursions |
| VWM | 136 V - maximum continuous reverse voltage before leakage exceeds 1 µA, matching 12 V–48 V system bus designs with 20 % margin |
| VC @ IPPM | 219 V - clamped voltage at 6.8 A peak pulse, limiting downstream component stress to safe levels during ISO 7637-2 Pulse 1/2b events |
| PPPM | 1500 W - peak pulse power handling with 10/1000 µs waveform, sufficient for lightning-induced surges per IEC 61000-4-5 Level 3 (1 kV/2 Ω) |
| IFSM | 200 A - 8.3 ms half-sine surge current rating, enabling robust protection against inductive kickback in solenoid drivers and relay coils |
| TJ max | +175 °C - extended junction temperature rating supports placement near heat-generating power stages without derating |
| RθJA | 75 °C/W - thermal resistance enables >6 W steady-state dissipation on minimal copper area, simplifying PCB layout in space-constrained modules |
Pinout & Package
Package: JEDEC DO-201AD (Case Style 1.5KE), axial-leaded molded epoxy body with matte tin-plated leads; RoHS-compliant and AEC-Q101 qualified (HE3 suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference node for unidirectional clamping | Connected to ground or low-side return path; absorbs positive transients when cathode is biased above anode by ≥VBR |
| Cathode | Clamping output terminal | Connected to protected line (e.g., 136 V rail); conducts surge current to anode when transient exceeds VWM, limiting voltage to ≤219 V |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enables stable VBR tolerance (±5 %) and <1 ns response time across –55 °C to +175 °C, critical for automotive cold-crank and hot-soak immunity |
| AEC-Q101 qualification | Validated for automotive-grade reliability including HTOL, TC, and UHAST - required for engine control units and ADAS power domains |
| 1500 W peak pulse power | Supports single-event surge suppression up to IEC 61000-4-5 4 kV (2 Ω source), eliminating need for cascaded protection stages |
| Low clamping ratio (VC/VBR ≈ 1.37) | Minimizes voltage overshoot during clamping, reducing stress on 200 V-rated MOSFETs and 250 V capacitors in DC-link circuits |
| JESD 201 Class 2 whisker resistance | HE3 suffix confirms compliance with stringent tin-whisker mitigation for long-life industrial deployments (>15 years field life) |

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-E3/52 | DO-214AA package; lower PPPM = 600 W; VC = 259 V @ 2.2 A; RθJA = 110 °C/W | Compact surface-mount form factor suitable for dense PCB layouts but requires larger copper area for thermal management | Select when board space is constrained and surge energy is limited to IEC 61000-4-5 Level 2 (0.5 kV); not recommended for automotive load-dump duty. |
| 1.5KE160A-E3/73 | Same 1.5KE package and electrical specs, but commercial-grade (non-AEC-Q101); identical VBR, VWM, VC, and PPPM | Approved for industrial and consumer use only; lacks automotive qualification testing and whisker resistance certification | Choose for cost-sensitive non-automotive applications where AEC-Q101 is not mandated, e.g., HVAC control boards or test equipment. |
Compared with SMBJ160A-E3/52, the 1.5KE160CHE3/73 delivers 2.5× higher surge power handling and superior thermal performance in through-hole mounting; versus 1.5KE160A-E3/73, it adds AEC-Q101 qualification and JESD 201 Class 2 whisker resistance - essential for automotive OEM production and long-life industrial deployments.

FAQ
What is the breakdown voltage tolerance for 1.5KE160CHE3/73?
The 1.5KE160CHE3/73 has a specified breakdown voltage range of 152 V to 168 V at 1 mA test current, representing a ±5 % tolerance around the nominal 160 V rating. This tight VBR window ensures consistent clamping onset across production lots and temperature extremes from –55 °C to +175 °C, critical for predictable protection in automotive and industrial systems.
Is 1.5KE160CHE3/73 suitable for bidirectional transient suppression?
No, the 1.5KE160CHE3/73 is a unidirectional TVS diode, indicated by the "A" suffix (not "CA"). It clamps only positive transients relative to its cathode; for bidirectional protection, Vishay offers the 1.5KE160CA variant. Using 1.5KE160CHE3/73 in AC-coupled or floating applications risks failure during negative excursions beyond its forward voltage rating.
How does the HE3 suffix affect the reliability of 1.5KE160CHE3/73?
HE3 denotes RoHS compliance plus AEC-Q101 qualification and JESD 201 Class 2 whisker resistance. For 1.5KE160CHE3/73, this means validated performance across 1000 thermal cycles (–40 °C to +125 °C), 1000 h HTOL at 175 °C, and immunity to tin whisker growth - directly supporting 15-year automotive field life and industrial equipment MTBF requirements.
What is the maximum clamping voltage of 1.5KE160CHE3/73 under surge conditions?
The 1.5KE160CHE3/73 clamps to a maximum of 219 V at its rated peak pulse current of 6.8 A (10/1000 µs waveform). This VC value is guaranteed across temperature and lifetime, providing a deterministic upper bound for protected circuit voltage stress - essential for selecting downstream components with appropriate voltage margins.
Can 1.5KE160CHE3/73 replace older 1N6299A devices in legacy designs?
Yes, 1.5KE160CHE3/73 is the direct successor to 1N6299A, sharing identical electrical specifications (VBR, VWM, VC, PPPM) and DO-201AD packaging. The HE3 suffix adds AEC-Q101 qualification and enhanced process controls, making 1.5KE160CHE3/73 fully backward-compatible while improving long-term reliability in new and refreshed designs.
