Product details
Overview
1.5KE13CA R0G from Taiwan Semiconductor is a bidirectional 1500W transient voltage suppressor (TVS) diode in DO-201 package, with nominal breakdown voltage 13V, working stand-off voltage 11.1V, clamping voltage 18.2V at 86A peak pulse current, and AEC-Q101 qualification for automotive use. It protects power rails and signal lines against ISO 7637-2 Pulse 1/2a/2b/3a/3b transients in automotive ECUs and industrial control modules.
For engineers reviewing the 1.5KE13CA R0G datasheet, 1.5KE13CA R0G pinout, 1.5KE13CA R0G application, or 1.5KE13CA R0G equivalent, key selection criteria include bidirectional clamping capability, 18.2V VC@IPP, DO-201 mechanical compatibility, AEC-Q101 qualification status, and compliance with ISO 7637-2 immunity requirements.
Technical Context
This bidirectional TVS diode operates symmetrically in both polarities, delivering consistent clamping performance across positive and negative transients. Its low dynamic impedance and sub-5ns response time ensure rapid suppression of fast-rising EFT and load-dump events without affecting system timing.
The device sustains 1500W peak pulse power per 10/1000μs waveform at 25°C, derating linearly above ambient temperature per Fig.2. Junction temperature range spans −55°C to +175°C, supporting under-hood automotive deployment without thermal derating penalties in standard PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 12.4V / 13.7V @ 1.0mA - Ensures reliable conduction onset within tight tolerance for predictable clamping threshold |
| VWM | 11.1V - Maximum continuous reverse operating voltage; sets safe margin below breakdown for stable standby operation |
| VC @ IPP | 18.2V @ 86A - Clamped voltage during full 1500W surge; defines worst-case overvoltage seen by protected ICs |
| PPK | 1500W - Peak pulse power handling per 10/1000μs waveform; enables robust protection against automotive load dump |
| IPP | 86A - Peak impulse current capacity; determines minimum series impedance required for effective energy diversion |
| TJ max | +175°C - Maximum junction temperature; supports placement near heat sources in engine control units |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD stress per AEC standard |
Pinout & Package
Package: DO-201 axial leaded package with cathode band marking (bidirectional symmetry means no polarity-dependent orientation; cathode band indicates terminal identification per JEDEC standard).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional transient conduction path | Either terminal serves as anode or cathode depending on transient polarity; no DC bias dependency |
| Leads (Tin-plated) | PCB interconnect and thermal path | Pure tin plating ensures J-STD-002 solderability; 9.5mm lead length supports 5W steady-state dissipation on 16mm² copper pad |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Identical VBR and VC in both directions - eliminates need for polarity-aware layout in differential or AC-coupled lines |
| ISO 7637-2 compliance | Validated against Pulse 1 (inductive switch-off), Pulse 2a/2b (battery disconnect), Pulse 3a/3b (EFT) - meets OEM ECU immunity requirements |
| Low leakage | <1μA @ 11.1V - prevents standby current drain in always-on automotive modules |
| Fast response | <5.0ns turn-on - captures sub-microsecond transients before downstream ICs experience overstress |
| Halogen-free & RoHS | Complies with IEC 61249-2-21 and EU RoHS Directive - satisfies environmental compliance for global vehicle programs |
Applications
| Automotive Body Control Module (BCM) | Industrial PLC Digital Input Card |
|---|---|
Use Scenario: Protects 12V supply rail and LIN bus lines from battery load dump and alternator ripple in BCMs. IC Role / Device Role / Timing Role: Bidirectional TVS clamps both positive and negative transients on shared power/signal lines without polarity constraints. Use Value: Maintains <18.2V clamping during 86A surges, keeping MCU and transceiver ICs within absolute maximum ratings during ISO 7637-2 Pulse 2b events. |
Use Scenario: Shields 24V digital input optocouplers from inductive kickback when switching solenoids or relays. IC Role / Device Role / Timing Role: Fast-response TVS diverts energy before optocoupler input stage fails, preserving isolation integrity. Use Value: Sub-5ns response limits voltage overshoot to ≤18.2V, preventing premature aging of input-stage ESD structures in industrial-grade optos. |
| LED Headlamp Driver Unit | Automotive Infotainment Power Supply |
Use Scenario: Guards buck converter input against load dump transients in LED headlamp systems with high-current drivers. IC Role / Device Role / Timing Role: High-power TVS absorbs 1500W surge energy, shielding controller ICs and MOSFET gate drivers. Use Value: 175°C max junction temperature allows direct mounting near power inductors, reducing board area vs. remote placement. |
Use Scenario: Secures USB-C PD and CAN-FD power domains against coupled transients from adjacent high-noise subsystems. IC Role / Device Role / Timing Role: Bidirectional clamping protects dual-rail supplies (5V/3.3V) without requiring separate unidirectional devices. Use Value: Symmetric VBR (12.4–13.7V) and VC (18.2V) ensure equal protection margin for positive/negative rail faults. |
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 SMAJ13CA | Same DO-214AC (SMA) package; 13V nominal, 18.2V VC, but rated for 400W only - lower surge capacity than 1.5KE13CA R0G's 1500W | Not suitable for ISO 7637-2 Pulse 2b or load dump; limited to low-energy ESD/EFT scenarios | Select only where space-constrained layouts prevent DO-201 use and surge energy is ≤400W |
| ON Semiconductor 1.5SMC13CA | DO-214AB (SMC) package; identical 13V/18.2V specs and 1500W rating, but not AEC-Q101 qualified | Acceptable for industrial/commercial use; excluded from automotive production due to missing AEC-Q101 validation | Prefer 1.5KE13CA R0G for automotive programs; use 1.5SMC13CA only if AEC-Q101 is not mandated |
Compared with SMAJ13CA and 1.5SMC13CA, the 1.5KE13CA R0G uniquely combines DO-201 mechanical robustness, full 1500W surge rating, and AEC-Q101 qualification-making it the only option qualified for front-end protection in automotive power domains subject to load dump and ISO 7637-2 testing.

FAQ
What does the 'CA' suffix indicate in 1.5KE13CA R0G?
The 'CA' suffix in 1.5KE13CA R0G denotes bidirectional configuration - meaning the device provides symmetrical transient suppression for both positive and negative voltage excursions. This differs from 'A' suffix parts (e.g., 1.5KE13A), which are unidirectional and require correct polarity orientation during placement. The CA version eliminates polarity concerns in AC-coupled or floating signal paths.
Is 1.5KE13CA R0G AEC-Q101 qualified?
Yes, 1.5KE13CA R0G is AEC-Q101 qualified, as confirmed in Taiwan Semiconductor's official 1.5KE series documentation (Version O2104). This qualification covers stress tests including high-temperature reverse bias (HTRB), temperature cycling, and ESD, validating its suitability for automotive electronic control units deployed in harsh environments.
What is the clamping voltage of 1.5KE13CA R0G at its rated surge current?
The clamping voltage (VC) of 1.5KE13CA R0G is 18.2V at 86A peak pulse current (IPP), measured per 10/1000μs waveform. This value represents the maximum voltage imposed on protected circuitry during full-rated surge events and is critical for ensuring downstream ICs remain within their absolute maximum voltage ratings.
Can 1.5KE13CA R0G replace unidirectional 1.5KE13A in existing designs?
No - 1.5KE13CA R0G cannot directly replace unidirectional 1.5KE13A without layout review. While both share identical VBR (12.4–13.7V) and VC (18.2V), the CA variant has symmetrical terminals and no cathode band functional significance, whereas the A variant requires correct anode/cathode orientation. PCB footprint may be identical, but schematic symbol and routing must reflect bidirectional behavior.
What packaging options are available for 1.5KE13CA R0G?
1.5KE13CA R0G is supplied in DO-201 axial package, available in 1,250-piece tape-and-reel (R0G suffix) and 500-piece ammo box formats. The 'R0G' in the part number explicitly denotes the tape-and-reel packaging variant per Taiwan Semiconductor's ordering code convention, enabling automated SMT placement despite its through-hole form factor.
