Product details
Overview
1.5KE130CA R0G from Taiwan Semiconductor is a bidirectional 1500W transient voltage suppressor (TVS) diode in DO-201 package, with nominal breakdown voltage 130V, clamping voltage 187V at 8.4A peak pulse current, and working stand-off voltage 105V. It protects automotive and industrial power rails against ISO 7637-2 Pulse 1/2a/2b/3a/3b transients.
For engineers reviewing the 1.5KE130CA R0G datasheet, 1.5KE130CA R0G pinout, 1.5KE130CA R0G application, or 1.5KE130CA R0G equivalent, this part delivers AEC-Q101-qualified surge immunity, sub-5ns response time, and <1µA leakage above 10V - critical for ESD and inductive switching protection in 12V/24V systems.
Technical Context
This bidirectional TVS operates symmetrically in both polarities, with VBR min/max of 117V/143V at 1.0mA test current and temperature coefficient of 0.107%/°C. Its 10/1000μs waveform rating supports 1500W non-repetitive peak power dissipation at 25°C, derating linearly above ambient.
Designed for unclamped inductive load switching and fast electrical fast transient (EFT) suppression, it exhibits low dynamic impedance and clamps to ≤187V at 8.4A IPP, limiting voltage overshoot across protected ICs or MOSFET gates without forward conduction.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 117V / 143V at 1.0mA - defines reliable turn-on threshold under transient stress |
| VWM | 105V - maximum continuous DC or RMS voltage before significant leakage |
| VC @ IPP | 187V at 8.4A - peak clamped voltage during 10/1000μs surge, limiting downstream overvoltage |
| PPK | 1500W - peak pulse power handling capability per JEDEC standard waveform |
| IPP | 8.4A - maximum non-repetitive peak impulse current the device safely clamps |
| TJ max | +175°C - junction temperature limit enabling operation in under-hood automotive environments |
| Response time | <5.0ns - time from 0V to VBR in bidirectional mode, critical for ESD/EFT immunity |
Pinout & Package
DO-201 axial-leaded package with cathode band marking for polarity identification; bidirectional symmetry means no functional anode/cathode distinction - both terminals are electrically identical.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (marked end) | Transient current entry point (bidirectional) | Terminal accepts surge current in either direction; marking indicates physical orientation only |
| Cathode (unmarked end) | Transient current exit point (bidirectional) | Electrically identical to anode; no functional polarity - used for mechanical alignment |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing |
| ISO 7637-2 compliance | Meets Pulse 1 (inductive load dump), Pulse 2a/2b (switching transients), and Pulse 3a/3b (EFT) requirements |
| Low dynamic impedance | Enables tight clamping with minimal voltage overshoot during high-di/dt events |
| Halogen-free & RoHS | Complies with IEC 61249-2-21 and EU RoHS Directive 2011/65/EU for green manufacturing |
| UL 94V-0 molding | Flame-retardant epoxy compound prevents fire propagation in fault conditions |

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 SMAJ130CA | Same DO-214AC (SMA) package; 130V VBR, 187V VC, but 400W PPK rating | Lower surge capacity limits use to lower-energy transients; not AEC-Q101 qualified | Select when space-constrained layouts require surface-mount and surge demands are ≤400W |
| ON Semiconductor 1.5SMC130CA | DO-214AB (SMC) package; identical 130V VBR, 187V VC, 1500W rating, but no AEC-Q101 option | Larger footprint than DO-201; thermal performance differs due to package geometry and lead length | Choose for higher-power industrial designs where board space permits larger SMC outline |
Compared with SMAJ130CA and 1.5SMC130CA, the 1.5KE130CA R0G uniquely combines axial DO-201 form factor, AEC-Q101 qualification, and full 1500W surge rating - making it the preferred choice for automotive under-hood and high-reliability industrial power inputs where through-hole mounting and automotive validation are required.

FAQ
What does the 'CA' suffix indicate in 1.5KE130CA R0G?
The 'CA' suffix in 1.5KE130CA R0G denotes bidirectional configuration - meaning the device functions identically in both polarities, with symmetrical breakdown and clamping characteristics. This enables single-component protection of AC-coupled signals or DC rails subject to reverse-polarity transients, unlike unidirectional 'C' variants which require correct orientation.
Is 1.5KE130CA R0G AEC-Q101 qualified?
Yes, 1.5KE130CA R0G is AEC-Q101 qualified, as confirmed by Taiwan Semiconductor's official documentation for the 1.5KE series. This qualification covers stress tests including high-temperature reverse bias (HTRB), temperature cycling, and ESD (HBM ≥8kV, CDM ≥1kV), validating its suitability for automotive under-hood and chassis applications.
What is the clamping voltage of 1.5KE130CA R0G at its rated peak pulse current?
The clamping voltage of 1.5KE130CA R0G is 187V at 8.4A peak pulse current (IPP) under the standard 10/1000μs waveform. This value is measured per JEDEC test conditions and represents the maximum voltage seen across the device during a full-rated surge event - a key parameter for ensuring downstream components remain within safe operating limits.
Can 1.5KE130CA R0G be used in place of a unidirectional TVS like 1.5KE130C?
No - 1.5KE130CA R0G is bidirectional and cannot directly replace unidirectional 1.5KE130C without circuit review. While both share identical VBR and VC ratings, the unidirectional version conducts only in reverse bias and requires correct polarity placement. Using 1.5KE130CA R0G in its place introduces no polarity constraint but may alter leakage behavior in DC-biased circuits.
What packaging options are available for 1.5KE130CA R0G?
1.5KE130CA R0G is supplied in DO-201 axial package, available in tape-and-reel format (1,250 units per reel) and ammo box (500 units per box). The 'R0G' suffix specifically denotes green (halogen-free) molding compound and tape-and-reel packaging - confirming compliance with RoHS and IEC 61249-2-21 standards.
