Product details
Overview
1.5KE36A R0G 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 30.8V, clamping voltage 49.9V at 31A peak pulse current, and fast response time <1.0ps - used for automotive power line surge protection per ISO 7637-2 Pulse 1/2a/2b/3a/3b.
For engineers reviewing the 1.5KE36A R0G datasheet, 1.5KE36A R0G pinout, 1.5KE36A R0G application, or 1.5KE36A R0G equivalent, key selection criteria include VWM (30.8V), VC (49.9V @ 31A), TJ max (175°C), AEC-Q101 qualification status, and DO-201 mechanical compatibility with high-surge industrial PCB layouts.
Technical Context
This unidirectional TVS diode operates as a clamping device across DC power rails or signal lines, triggering when transient voltage exceeds its 34.2–37.8V breakdown range at 1mA test current. It delivers 1500W peak pulse power under 10/1000μs waveform while maintaining low dynamic impedance and sub-1.0ps response from 0V to VBR.
Designed for robustness in harsh environments, it meets ISO 7637-2 immunity requirements for automotive electronics and supports steady-state power dissipation of 5W at TL = 75°C on 16mm × 16mm copper pad. Its junction temperature range spans −55°C to +175°C, and leakage current remains below 1μA above 10V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR Min/Max | 34.2V / 37.8V at IT = 1mA - defines reliable turn-on threshold for overvoltage clamping |
| VWM | 30.8V - maximum continuous operating voltage before leakage rises significantly |
| VC @ IPP | 49.9V at 31A - clamped voltage during 10/1000μs surge, limiting downstream IC stress |
| PPK | 1500W - peak surge power handling capability under standardized transient waveform |
| IPP | 31A - maximum non-repetitive peak impulse current the device safely clamps |
| TJ Max | +175°C - enables operation in under-hood automotive or high-ambient industrial environments |
| Leakage ID | <1μA @ VWM - ensures minimal standby power loss and signal integrity in always-on circuits |
Pinout & Package
DO-201 axial-leaded package with cathode band marking; leads are pure tin plated, solderable per J-STD-002, and meet JESD 201 Class 2 whisker resistance. Weight ≈ 0.090g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference node | Connected to ground or low-voltage rail; forms clamping path with cathode |
| Cathode | High-side transient input node | Connected to protected line (e.g., 24V supply); conducts surge current to ground when VAK > VBR |
Key Features

| 1500W surge rating | Withstands severe load dump and inductive switching transients without degradation |
| Clamping voltage 49.9V | Keeps protected 3.3V/5V/12V logic and MCU I/O within safe operating limits during surges |
| Response time <1.0ps | Engages before most system-level transients propagate, minimizing propagation delay risk |
| RoHS & halogen-free | Complies with IEC 61249-2-21 and global environmental directives for PCB assembly |
Applications
| Automotive Power Line Protection | Industrial PLC Input Protection |
|---|---|
Use Scenario: 12V/24V battery-fed ECUs exposed to ISO 7637-2 Pulse 1 (inductive load disconnect) and Pulse 2a (supply interruption). IC Role / Device Role: Unidirectional TVS placed between power rail and chassis ground to clamp negative-going transients. Use Value: Limits voltage excursion to ≤49.9V, protecting CAN transceivers, microcontrollers, and voltage regulators from permanent damage. | Use Scenario: Digital input modules receiving 24VDC signals from field sensors in factory automation systems. IC Role / Device Role: Front-end transient suppressor on each input channel before optocoupler or level-shifter. Use Value: Absorbs EFT bursts (IEC 61000-4-4) and lightning-induced surges up to 1500W without latch-up or parameter shift. |
| LED Driver Overvoltage Clamp | Telecom DC Feed Protection |
Use Scenario: Constant-current LED drivers powered from unregulated 36V bus in outdoor signage or street lighting. IC Role / Device Role: Standoff protector parallel to driver IC input to prevent overvoltage failure during hot-plug or capacitor discharge events. Use Value: Maintains VWM = 30.8V margin below nominal 36V rail while clamping spikes to 49.9V - preserving driver FET gate oxide integrity. | Use Scenario: Central office equipment supplying −48V DC power over long copper pairs to remote DSLAMs or VoIP phones. IC Role / Device Role: Bidirectional-capable variant not applicable; this unidirectional 1.5KE36A R0G used on positive side of split-supply feed circuits. Use Value: Blocks positive surges on +24V auxiliary rails while allowing normal bias current flow - critical for fault-tolerant telecom power distribution. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ36A | Same DO-214AC (SMA) package; lower PPK = 400W; VC = 58.1V @ 6.9A | Not suitable for 1500W ISO 7637-2 Pulse 5a; limited to lower-energy ESD/EFT scenarios | Select only where space constraints favor surface-mount and surge energy is ≤400W |
| ON Semiconductor 1N6284A | Identical electrical specs and DO-201 package; same VBR, VC, PPK, and AEC-Q101 qualification | No functional difference; validated drop-in replacement per manufacturer cross-reference | Preferred for dual-sourcing; identical performance and footprint - no layout change required |
Compared with SMAJ36A, 1.5KE36A R0G delivers 3.75× higher surge power and 8.2V lower clamping voltage, enabling robust automotive compliance; versus 1N6284A, it offers identical protection but differs in traceability, date coding, and regional manufacturing origin - both are electrically interchangeable.

FAQ
What is the breakdown voltage range of the 1.5KE36A R0G?
The 1.5KE36A R0G has a guaranteed breakdown voltage range of 34.2V to 37.8V at 1mA test current (VBR), measured per JEDEC standard. This range ensures predictable clamping onset across production lots and temperature extremes, supporting reliable overvoltage protection design margins in 36V nominal systems.
Is the 1.5KE36A R0G AEC-Q101 qualified?
Yes, the 1.5KE36A R0G is AEC-Q101 qualified, as confirmed by Taiwan Semiconductor's official documentation and ordering code suffix "A" (indicating AEC-Q101 compliance). This qualification covers stress tests including high-temperature reverse bias, temperature cycling, and ESD, making 1.5KE36A R0G suitable for automotive powertrain and body electronics applications.
What is the maximum clamping voltage of the 1.5KE36A R0G during a surge event?
The maximum clamping voltage of the 1.5KE36A R0G is 49.9V at 31A peak pulse current (IPP) under the 10/1000μs waveform. This value represents the upper limit of voltage seen by downstream circuitry during worst-case surge conditions, directly informing safe operating area calculations for protected ICs and MOSFETs in the 1.5KE36A R0G application.
Can the 1.5KE36A R0G be used in bidirectional configurations?
No, the 1.5KE36A R0G is a unidirectional TVS diode and must be used with correct polarity - cathode to the protected line, anode to ground. For bidirectional protection, Taiwan Semiconductor specifies part numbers ending in "CA" (e.g., 1.5KE36CA); using 1.5KE36A R0G in reverse-biased configuration will not provide symmetrical clamping and may fail catastrophically under negative transients.
What package type does the 1.5KE36A R0G use, and what are its mechanical features?
The 1.5KE36A R0G uses the DO-201 axial-leaded package with cathode band marking, pure tin-plated leads compliant with J-STD-002 solderability, and UL 94V-0 molding compound. Its weight is approximately 0.090g, and it meets JESD 201 Class 2 whisker resistance - all verified in Taiwan Semiconductor's mechanical data sheet for the 1.5KE36A R0G.
