Product details
Overview
1.5KE36CAHE3_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 36 V breakdown voltage (VBR = 34.2–37.8 V at 1 mA), 1500 W peak pulse power (10/1000 µs), clamping voltage of 49.9 V at 30.1 A, and operates across –55 °C to +175 °C junction temperature. It is used to protect MOSFETs, ICs, and sensor interfaces against lightning-induced transients and inductive switching spikes in automotive and industrial systems.
For engineers reviewing the 1.5KE36CAHE3_B/C datasheet, 1.5KE36CAHE3_B/C pinout, 1.5KE36CAHE3_B/C application, or 1.5KE36CAHE3_B/C equivalent, this device delivers verified bidirectional clamping performance with AEC-Q101 qualification, RoHS-compliant HE3 packaging, and JESD 201 Class 2 whisker resistance - critical for automotive-grade reliability and board-level ESD/surge hardening.
Technical Context
This TVS diode employs a glass-passivated silicon junction optimized for sub-nanosecond response (<1 ns) and low incremental surge resistance. Its bidirectional architecture enables symmetrical clamping in AC-coupled or floating signal paths without polarity constraints.
It is rated for 1500 W peak pulse power under standardized 10/1000 µs waveform conditions, with thermal resistance of 15.4 °C/W (junction-to-lead) and 75 °C/W (junction-to-ambient), supporting robust transient energy dissipation in compact through-hole layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 34.2 V / 37.8 V at 1 mA - defines precise clamping onset threshold for overvoltage detection |
| VWM | 30.8 V - maximum continuous reverse working voltage before leakage exceeds 1 µA |
| VC @ IPPM | 49.9 V at 30.1 A - actual clamped voltage during full 1500 W surge, limiting downstream stress |
| PPPM | 1500 W - peak transient power handling capability per 10/1000 µs waveform, enabling lightning surge compliance |
| Junction Temp Range | –55 °C to +175 °C - supports operation in under-hood automotive and industrial environments |
| Package | Case Style 1.5KE - axial-leaded DO-201AD package with 0.375" lead length, UL 94 V-0 molded epoxy body |
| AEC-Q101 Qualified | Yes - validated for automotive electronics per stress test requirements including HTOL, TCT, and HTRB |
Pinout & Package
1.5KE36CAHE3_B/C uses a two-terminal axial-leaded DO-201AD (Case Style 1.5KE) package. Bidirectional construction means no cathode/anode marking; both leads are electrically symmetric.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetric) | Transient current path | Both terminals conduct identically during positive or negative surges - no polarity orientation required on PCB |
| Leads (matte tin plated) | Thermal and electrical interface | Solderable per J-STD-002/JESD 22-B102; supports 275 °C solder dip (10 s max); JESD 201 Class 2 whisker resistant |

| 1500 W peak pulse power | Meets IEC 61000-4-5 Level 4 (4 kV line-to-line) surge immunity when properly mounted with low-inductance layout |
| Bidirectional clamping | Protects AC-coupled data lines (e.g., RS-485, CAN FD physical layer) without external polarity management |
| AEC-Q101 qualification | Validated for automotive powertrain, body control, and ADAS modules requiring zero-failure field performance |
| UL 94 V-0 epoxy molding | Prevents flame propagation during catastrophic failure, satisfying safety-critical system enclosure requirements |
Applications
| Automotive Power Distribution | Industrial Sensor Signal Conditioning |
|---|---|
Use Scenario: Protection of 12 V battery-fed ECUs against load dump (ISO 7637-2 Pulse 5a) and alternator transients. IC Role / Device Role / Timing Role: Primary shunt clamp placed upstream of DC-DC converters and microcontrollers. Use Value: Clamps to ≤49.9 V within <1 ns, preventing latch-up or gate oxide damage in downstream MOSFETs and PMICs. |
Use Scenario: Shielding 4–20 mA current loop transmitters from EFT bursts (IEC 61000-4-4) and induced surges on factory floor wiring. IC Role / Device Role / Timing Role: Bidirectional transient limiter across loop supply terminals and signal return. Use Value: Maintains loop integrity by limiting common-mode voltage excursions to <50 V while preserving analog accuracy below VWM. |
| Telecom Line Interface | Consumer Appliance Motor Control |
Use Scenario: Surge protection on POTS or DSL line cards exposed to lightning-induced longitudinal surges (ITU-T K.20/K.21). IC Role / Device Role / Timing Role: First-stage protector in hybrid transformer-coupled front-end, paired with gas discharge tube (GDT). Use Value: Fast response ensures GDT triggers only after initial clamping, extending overall system surge lifetime. |
Use Scenario: Suppressing commutation spikes from brushed DC motors in washing machines and HVAC blowers. IC Role / Device Role / Timing Role: Across-motor terminals to absorb inductive kickback energy during PWM switching. Use Value: Limits flyback voltage to <50 V, eliminating need for snubber RC networks and reducing BOM count. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ36CA | Surface-mount SMB package (3.5 mm × 4.6 mm); lower 600 W PPPM; VC = 58.1 V at 10.3 A | Requires PCB rework for SMT assembly; less suitable for high-current chassis-grounded protection | Select when space-constrained layouts demand SMT integration and peak surge energy is ≤600 W |
| 1.5KE36AHE3_B/C | Unidirectional variant; same VBR, VC, and PPPM; includes cathode band marking | Only usable in DC-biased circuits where polarity is fixed; cannot protect AC or floating nodes | Choose only for unidirectional rails (e.g., +12 V supply) where polarity-aware placement is acceptable |
Compared with SMBJ36CA and 1.5KE36AHE3_B/C, the 1.5KE36CAHE3_B/C uniquely combines through-hole mechanical robustness, full 1500 W surge capacity, and true bidirectional symmetry - making it optimal for high-reliability chassis-level protection where layout flexibility and polarity independence are mandatory.

FAQ
What is the breakdown voltage tolerance of the 1.5KE36CAHE3_B/C?
The 1.5KE36CAHE3_B/C has a specified breakdown voltage range of 34.2 V to 37.8 V at 1 mA test current, corresponding to ±5.6% tolerance around the nominal 36 V rating. This tight VBR window ensures predictable clamping onset across production lots and temperature extremes, critical for coordinating with downstream overvoltage protection thresholds in systems using the 1.5KE36CAHE3_B/C.
Is the 1.5KE36CAHE3_B/C suitable for automotive applications?
Yes, the 1.5KE36CAHE3_B/C is AEC-Q101 qualified (per note 2 in the Vishay datasheet), covering stress tests including high-temperature operating life, temperature cycling, and highly accelerated stress testing. Its –55 °C to +175 °C operating range and robust DO-201AD package make it appropriate for engine control units, body electronics, and ADAS modules where the 1.5KE36CAHE3_B/C provides certified surge resilience.
How does the clamping voltage of the 1.5KE36CAHE3_B/C compare to its breakdown voltage?
The 1.5KE36CAHE3_B/C clamps to 49.9 V at its rated peak pulse current of 30.1 A, which is approximately 39% above its minimum breakdown voltage of 34.2 V. This VC/VBR ratio reflects low incremental surge resistance and efficient energy absorption - a key design parameter ensuring protected ICs see minimal overvoltage overshoot during transients handled by the 1.5KE36CAHE3_B/C.
What is the meaning of the "HE3_B/C" suffix in 1.5KE36CAHE3_B/C?
The "HE3" denotes RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance; "B/C" indicates revision level and packaging format (13" paper tape and reel, 1400 pcs per reel). This suffix confirms the 1.5KE36CAHE3_B/C meets automotive-grade reliability standards and is supplied in standard automated assembly-compatible packaging.
Can the 1.5KE36CAHE3_B/C be used in parallel to increase surge handling capacity?
While the 1.5KE36CAHE3_B/C datasheet notes TVS diodes can be used in parallel to increase peak power ratings, doing so requires matched VBR devices and careful layout to ensure current sharing. For the 1.5KE36CAHE3_B/C, parallel use is feasible but not recommended without derating and verification - single-device 1500 W capability typically suffices for most IEC 61000-4-5 Level 4 applications without adding complexity to the 1.5KE36CAHE3_B/C implementation.
