Product details
Overview
1.5KE36CAHB0G from Taiwan Semiconductor is a bidirectional 1500W transient voltage suppressor (TVS) diode in DO-201 package, with nominal breakdown voltage 36V, working stand-off voltage 29.1V, clamping voltage 52.0V at 30A peak impulse current, and AEC-Q101 qualification for automotive-grade surge protection.
For engineers reviewing the 1.5KE36CAHB0G datasheet, 1.5KE36CAHB0G pinout, 1.5KE36CAHB0G application, or 1.5KE36CAHB0G equivalent, this device serves as a robust, low-leakage (≤1µA @ 29.1V), fast-response (<5ns) bidirectional clamp for ISO 7637-2 Pulse 1/2a/2b/3a/3b compliance in automotive power line and ECU interface protection.
Technical Context
This bidirectional TVS operates symmetrically in both polarities, delivering consistent clamping performance up to 1500W peak pulse power at 10/1000μs waveform. Its junction temperature range spans −55°C to +175°C, supporting under-hood automotive environments.
It features low dynamic impedance and a temperature coefficient of VBR at 0.099%/°C, ensuring stable breakdown behavior across thermal extremes. The device meets JESD201 Class 2 whisker resistance and RoHS/halogen-free requirements per IEC 61249-2-21.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 29.1 V - Maximum continuous reverse operating voltage before leakage exceeds 1 µA; defines safe DC/AC bias margin. |
| VBR min / max | 32.4 V / 39.6 V @ 1.0 mA - Verified breakdown threshold range ensures reliable turn-on during transients without premature conduction. |
| VC @ IPP | 52.0 V @ 30 A - Clamped voltage during 10/1000μs surge; limits downstream IC stress to safe levels. |
| PPK | 1500 W - Peak pulse power handling capacity per JEDEC standard; supports high-energy load dump events. |
| IPP max | 30 A - Maximum non-repetitive peak impulse current; determines survivability against ISO 7637-2 Pulse 5a (load dump). |
| TJ max | +175 °C - Maximum junction temperature; enables placement near heat sources in engine control units. |
| Response time | <5 ns - Bidirectional turn-on latency; critical for suppressing EFT (IEC 61000-4-4) and ESD-induced edge transients. |
Pinout & Package
DO-201 axial leaded package with cathode band marking for polarity identification; leads are pure tin plated, solderable per J-STD-002, and meet UL 94V-0 flammability rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Current entry terminal in reverse bias | Connected to protected line; forms symmetrical clamp path with cathode during bidirectional surges. |
| Cathode (banded end) | Current exit terminal in reverse bias | Typically tied to ground or common reference; completes low-impedance surge shunt path. |
Key Features
| Feature | Design Value |
|---|---|

|---|---|
|
Use Scenario: Protecting LIN/CAN bus nodes and microcontroller I/O from battery line transients including load dump and jump-start spikes. IC Role / Device Role / Timing Role: Bidirectional voltage clamp placed between supply rail and ground, limiting transient overvoltage to ≤52.0 V during ISO 7637-2 Pulse 5a. Use Value: Prevents latch-up or gate oxide damage in 3.3V/5V MCUs and transceivers by holding rail voltage within safe operating area during 1500W surges. |
Use Scenario: Safeguarding analog front-end inputs of pressure, temperature, and position sensors exposed to EFT noise in factory automation systems. IC Role / Device Role / Timing Role: Fast-acting shunt element across sensor signal lines and ground, activated within 5 ns to suppress 5 kV EFT bursts per IEC 61000-4-4. Use Value: Maintains signal integrity and measurement accuracy by clamping induced transients below ADC input absolute maximum ratings (e.g., ±20 V). |
| LED Lighting Driver Protection | DC Motor Control Board Protection |
|
Use Scenario: Shielding constant-current LED driver ICs from inductive kickback generated by hot-plug events or dimmer switching. IC Role / Device Role / Timing Role: Parallel-connected TVS on output stage, conducting surge energy away from MOSFET gates and current-sense resistors during 10/1000μs transients. Use Value: Extends driver lifetime by preventing gate oxide rupture and sense resistor drift caused by repeated 30 A impulse currents. |
Use Scenario: Suppressing back-EMF spikes from brushed DC motors during PWM commutation and emergency stop in robotics actuators. IC Role / Device Role / Timing Role: Clamp mounted across motor terminals or H-bridge supply rails, diverting inductive energy before it reaches gate drivers and logic ICs. Use Value: Eliminates reset faults and erratic behavior in motor controllers by limiting voltage overshoot to ≤52.0 V during 200 A IFSM surges. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ36CA | Lower peak power (600W), smaller SMB package (vs. DO-201), higher VC (60.0 V @ 10 A). | Not rated for AEC-Q101; limited to industrial/commercial use; unsuitable for automotive load dump. | Select when space-constrained PCB layout prioritizes footprint over 1500W surge headroom. |
| 1.5SMC36CA | Same 1500W rating and DO-214AB package; VBR 32.4–39.6 V matches 1.5KE36CAHB0G, but lacks AEC-Q101 certification. | Requires external validation for automotive deployment; no ISO 7637-2 Pulse 5a guarantee. | Choose only for cost-sensitive non-automotive designs where AEC-Q101 is not mandated. |
Compared with SMBJ36CA and 1.5SMC36CA, the 1.5KE36CAHB0G uniquely combines AEC-Q101 qualification, DO-201 mechanical robustness, and guaranteed ISO 7637-2 compliance - making it the sole option for production automotive ECUs requiring zero-layout change replacement of legacy 1.5KE series devices.

FAQ
What does the "HB0G" suffix mean in 1.5KE36CAHB0G?
The "HB0G" suffix in 1.5KE36CAHB0G indicates AEC-Q101 qualification ("H"), green halogen-free molding compound ("G"), and ammo box packaging (500 units per box, "B0"). This distinguishes it from tape-and-reel variants and confirms compliance with automotive environmental and reliability standards. The 1.5KE36CAHB0G meets JESD201 Class 2 whisker resistance and RoHS directives.
Is 1.5KE36CAHB0G unidirectional or bidirectional?
The "CA" in 1.5KE36CAHB0G denotes bidirectional configuration - meaning it provides symmetrical clamping in both polarities, with identical VBR, VC, and IPP characteristics for positive and negative transients. This makes the 1.5KE36CAHB0G ideal for protecting AC-coupled interfaces or differential buses like CAN where polarity reversal occurs.
What is the maximum clamping voltage of 1.5KE36CAHB0G at rated surge current?
The maximum clamping voltage (VC) of 1.5KE36CAHB0G is 52.0 V at 30 A peak impulse current (IPP) under the standard 10/1000 μs waveform. This value is measured per JEDEC JESD22-A115 and guarantees that downstream circuitry remains within safe operating voltage limits during worst-case surge events.
Can 1.5KE36CAHB0G replace older 1.5KE36CA parts without design changes?
Yes - the 1.5KE36CAHB0G maintains identical electrical specifications, DO-201 mechanical dimensions, and pinout as legacy 1.5KE36CA variants. Its AEC-Q101 qualification and halogen-free construction add reliability without requiring PCB or schematic modifications, enabling drop-in upgrade for automotive production programs.
Does 1.5KE36CAHB0G meet ISO 7637-2 Pulse 5a (load dump) requirements?
Yes - the 1.5KE36CAHB0G is explicitly validated for ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b, and its 1500W peak power rating and 52.0 V clamping voltage enable compliance with Pulse 5a (load dump) when used with appropriate series impedance. The 1.5KE36CAHB0G's 175°C junction rating further ensures survival under sustained high-temperature load dump conditions.
