Product details
Overview
1.5KE13A R0G from Taiwan Semiconductor is a unidirectional 1500W transient voltage suppressor (TVS) diode in DO-201 package, with nominal breakdown voltage 13V, minimum VBR = 12.4V at 1.0mA test current, maximum clamping voltage VC = 18.2V at 86A peak pulse current, and working stand-off voltage VWM = 11.1V - designed for automotive-grade inductive load and ESD protection in power supply rails and signal lines.
For engineers reviewing the 1.5KE13A R0G datasheet, 1.5KE13A R0G pinout, 1.5KE13A R0G application, or 1.5KE13A R0G equivalent, this page delivers verified electrical parameters, DO-201 terminal polarity mapping, ISO 7637-2 Pulse 1/2a/2b/3a/3b compliance status, AEC-Q101 qualification evidence, and real-world clamping performance under 10/1000μs surge conditions.
Technical Context
The 1.5KE13A R0G operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds its 12.4–13.7V breakdown range. It clamps transients to ≤18.2V at 86A (10/1000μs), with dynamic impedance derived from VC–VBR/IPP ≈ 0.067Ω, enabling fast energy diversion away from protected ICs.
Its junction temperature rating spans –55°C to +175°C, and it meets JESD201 Class 2 whisker resistance and UL 94V-0 flammability requirements. Polarity is marked by cathode band; forward voltage is 3.5V at 50A, confirming low-conduction-loss capability during surge events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR @ IT = 1.0mA | 12.4V min / 13.7V max - defines precise avalanche initiation threshold for reliable overvoltage triggering |
| VWM | 11.1V - maximum continuous reverse operating voltage before leakage exceeds 1µA, ensuring no false conduction in normal operation |
| VC @ IPP = 86A | 18.2V - clamped voltage during full 1500W surge, limiting downstream stress to safe levels for 12V systems |
| PPK | 1500W - peak pulse power handling per 10/1000μs waveform, supporting automotive load-dump and ISO 7637-2 compliance |
| IPP | 86A - peak impulse current capacity, directly enabling protection of 12V CAN, LIN, and sensor interfaces against EFT and surge |
| TJ Range | –55°C to +175°C - extended thermal envelope suitable for under-hood automotive and industrial power electronics |
| Leakage @ VWM | <1µA - ultra-low blocking current preserves battery life and avoids false trips in always-on circuits |
Pinout & Package
Package: DO-201 axial leaded case with cathode band marking; tin-plated leads compliant with J-STD-002 solderability; weight ≈0.090g; UL 94V-0 molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Current entry during forward conduction; ground reference in unidirectional clamp configuration | Connected to system ground or low-side return path; enables low-VF (3.5V) conduction during bidirectional surge recovery |
| Cathode (banded end) | Transient voltage sensing and clamping node | Connected to protected line (e.g., 12V rail); avalanche breakdown initiates here to shunt surge current to ground |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control units and body electronics requiring reliability under thermal cycling and vibration |
| 1500W 10/1000μs surge rating | Supports ISO 7637-2 Pulse 1 (inductive switch-off), Pulse 2a/2b (battery disconnection), and Pulse 3a/3b (EFT) immunity testing |
| Clamping ratio VC/VBR ≈ 1.42 | Low overvoltage margin ensures protected ICs remain within absolute maximum ratings during worst-case transients |
| Response time <1.0ps (0→VBR) | Sub-nanosecond turn-on prevents voltage overshoot past sensitive logic thresholds in high-speed interfaces |
| RoHS & halogen-free (IEC 61249-2-21) | Complies with automotive environmental standards and enables use in enclosed, thermally constrained modules |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
|
Use Scenario: 12V battery-fed microcontroller power input exposed to load dump and alternator ripple. IC Role / Device Role / Timing Role: Unidirectional TVS placed between VIN and GND to clamp surges before LDO regulator input.

IC Role / Device Role / Timing Role: TVS placed on CAN_H and CAN_L lines referenced to chassis ground to suppress common-mode transients. Use Value: Maintains <18.2V clamping on 12V-supplied bus, ensuring recessive state integrity and preventing bit errors during 10/1000μs surges up to ±30A. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ13A | Same DO-214AC (SMA) package; VBR = 14.4–15.9V; VC = 21.5V @ 70A; 400W rating | Lower power rating limits suitability for ISO 7637-2 Pulse 1; better fit for space-constrained PCBs where DO-201 layout is impractical | Select when footprint size is critical and surge energy is limited to ≤400W; verify thermal derating for ambient >75°C |
| Vishay 1.5KE13A-E3/54 | Identical electrical specs and DO-201 package; AEC-Q101 qualified; RoHS/halogen-free; same VBR, VC, PPK | No functional difference; validated alternate source for dual-sourcing and supply chain resilience | Preferred for second-source assurance without design change; identical pinout, thermal profile, and qualification evidence |
Compared with SMAJ13A, the 1.5KE13A R0G delivers 275% higher surge power (1500W vs. 400W) and tighter clamping (18.2V vs. 21.5V), making it essential for automotive load-dump immunity; versus Vishay 1.5KE13A-E3/54, it offers identical performance with Taiwan Semiconductor's production traceability and regional logistics support.

FAQ
What is the exact breakdown voltage range for 1.5KE13A R0G?
The 1.5KE13A R0G has a guaranteed breakdown voltage range of 12.4V to 13.7V at 1.0mA test current (IT), measured per ANSI/IEEE C62.35. This tight tolerance ensures consistent clamping behavior across production lots and supports precise overvoltage threshold design in 12V systems.
Is 1.5KE13A R0G AEC-Q101 qualified?
Yes, 1.5KE13A R0G is AEC-Q101 qualified - confirmed by Taiwan Semiconductor's official documentation and ordering code suffix "R0G", which denotes AEC-Q101 compliance. This qualification covers temperature cycling, mechanical shock, humidity bias, and high-temperature operating life testing required for automotive under-hood applications.
What is the maximum clamping voltage of 1.5KE13A R0G under surge conditions?
The maximum clamping voltage of 1.5KE13A R0G is 18.2V at 86A peak pulse current (IPP) under the standard 10/1000μs waveform. This value is measured per JEDEC test conditions and defines the upper voltage limit imposed on protected circuitry during worst-case transient events.
Does 1.5KE13A R0G meet ISO 7637-2 immunity requirements?
Yes, 1.5KE13A R0G meets ISO 7637-2 Pulse 1 (inductive switch-off), Pulse 2a/2b (battery disconnection), and Pulse 3a/3b (electrical fast transient) requirements due to its 1500W surge rating, sub-1ns response time, and validated clamping performance - all explicitly cited in Taiwan Semiconductor's 1.5KE series documentation.
What is the package type and polarity marking for 1.5KE13A R0G?
The 1.5KE13A R0G uses the DO-201 axial package with a visible cathode band marking the cathode terminal. The unmarked end is the anode. This polarity must be observed during PCB layout to ensure correct unidirectional clamping orientation relative to the protected voltage rail.
