Product details
Overview
1.5KE36C from Taiwan Semiconductor is a unidirectional 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 pulse current, and junction temperature range −55°C to +175°C - designed for automotive and industrial power rail protection against ISO 7637-2 Pulse 1/2a/2b/3a/3b transients.
For engineers reviewing the 1.5KE36C datasheet, 1.5KE36C pinout, 1.5KE36C application, or 1.5KE36C equivalent, this page delivers verified electrical parameters, mechanical packaging details, real-world use cases in automotive ECU and industrial motor drives, and two validated alternative parts with documented differences in clamping performance and temperature coefficient.
Technical Context
The 1.5KE36C operates as a unidirectional avalanche diode, triggering at VBR = 32.4–39.6V (tested at 1.0mA), clamping transients to ≤52.0V at IPP = 30A under 10/1000μs waveform. Its low dynamic impedance and <1.0ps response time enable effective suppression of fast ESD and load-dump events.
It meets AEC-Q101 qualification (suffix H variant), supports steady-state power dissipation of 5W at TL = 75°C on 16mm × 16mm copper pad, and exhibits VBR temperature coefficient of 0.099%/°C - critical for stable clamping across automotive ambient ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 32.4V / 39.6V - ensures reliable turn-on above system operating voltage while avoiding false triggering |
| VWM | 29.1V - maximum continuous reverse voltage the device blocks without leakage exceeding 1µA |
| VC @ IPP = 30A | 52.0V - peak clamped voltage during 10/1000μs surge, defining protected circuit's maximum overvoltage stress |
| PPK | 1500W - single-pulse surge handling capability, sufficient for ISO 7637-2 Pulse 5a (load dump) |
| IFSM | 200A - non-repetitive forward surge rating, supporting high-current inductive switching events |
| TJ Range | −55°C to +175°C - enables deployment in under-hood automotive and industrial environments |
| Package | DO-201 - industry-standard axial leaded package with UL 94V-0 molding and tin-plated leads per J-STD-002 |
Pinout & Package
DO-201 package: axial-leaded, cylindrical epoxy body with cathode band marking for unidirectional polarity. Leads are pure tin-plated, solderable per J-STD-002, and meet JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Ground reference terminal | Connected to system ground or low-side return path; defines current flow direction during clamping |
| Cathode | Protected line terminal | Connected to the line being protected (e.g., battery rail); avalanche conduction occurs from cathode to anode during overvoltage |
Key Features
| Feature | Design Value |
|---|---|
| 1500W peak pulse power | Handles ISO 7637-2 Pulse 5a (load dump) up to 120V/350ms without failure |
| Clamping voltage ≤52.0V @ 30A | Keeps downstream 36V-rated components (e.g., MCU power supplies) within safe operating limits |
| Response time <1.0ps | Engages before ESD or fast transients propagate into sensitive analog or digital circuitry |
| AEC-Q101 qualified (H-suffix variants) | Validated for automotive electronics per stress test requirements including temperature cycling and HTRB |
| RoHS & halogen-free | Complies with IEC 61249-2-21 and EU RoHS Directive for environmentally constrained applications |
Applications
| Automotive Power Rail Protection | Industrial Motor Drive DC Bus |
|---|---|
Use Scenario: Protecting engine control unit (ECU) 12V supply from load dump transients during alternator disconnection. IC Role / Device Role / Timing Role: Unidirectional TVS placed between battery rail and input filter capacitor, conducting only during positive overvoltage events.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ36A | DO-214AC (SMA) package; VC = 58.1V @ 25.9A; 600W rating; lower thermal mass | Higher clamping voltage and lower surge rating limit use to lower-energy transients (e.g., ESD only) | Select when board space is constrained and surge energy is ≤600W; not suitable for ISO 7637-2 Pulse 5a |
| ON Semiconductor 1.5SMC36C | SMB package; VC = 58.1V @ 25.9A; same 1500W rating; 0.099%/°C tempco; RoHS/halogen-free | Identical clamping and power specs but SMB footprint requires PCB layout change | Choose for drop-in replacement if SMB is already used in design; verify thermal relief on 16mm² pad matches DO-201 derating |
Compared with 1.5KE36C, SMAJ36A offers smaller footprint but sacrifices 6.1V clamping margin and 900W surge capacity - limiting suitability to non-automotive applications; 1.5SMC36C matches power and clamping performance but demands PCB redesign due to SMB vs. DO-201 package mismatch.

FAQ
What is the exact breakdown voltage range for 1.5KE36C?
The 1.5KE36C has a guaranteed breakdown voltage range of 32.4V to 39.6V at 1.0mA test current (VBR min/max), measured per ANSI/IEEE C62.35. This range ensures consistent turn-on behavior across production lots and supports reliable coordination with upstream fusing and downstream IC voltage tolerances in 36V nominal systems.
Is 1.5KE36C unidirectional or bidirectional?
The 1.5KE36C is a unidirectional TVS diode, indicated by the "C" suffix and confirmed by its cathode band marking and specification of forward voltage (VF = 3.5V @ 50A). It conducts only during positive overvoltage events on the cathode terminal and blocks reverse voltage up to VWM = 29.1V.
What is the maximum clamping voltage of 1.5KE36C under surge conditions?
The 1.5KE36C clamps to a maximum of 52.0V at 30A peak pulse current (IPP) under the standard 10/1000μs waveform. This value is specified in the Electrical Specifications table and defines the upper voltage limit imposed on protected circuits during worst-case transient events.
Does 1.5KE36C meet automotive qualification standards?
The base 1.5KE36C is not AEC-Q101 qualified; however, the 1.5KE36CH variant (with "H" suffix) is explicitly AEC-Q101 qualified per the Ordering Information section. Engineers requiring automotive-grade reliability must specify the "H" version - the 1.5KE36C itself is suitable for industrial and commercial applications meeting ISO 7637-2.
What package type does 1.5KE36C use and what are its key mechanical properties?
The 1.5KE36C uses the DO-201 axial package: epoxy-molded, UL 94V-0 rated, with pure tin-plated leads compliant with J-STD-002 solderability and JESD 201 Class 2 whisker resistance. Its weight is approximately 0.090g, and polarity is marked by a cathode band - essential for correct orientation in unidirectional protection circuits.
