Product details
Overview
1.5KE160CA R0G from Taiwan Semiconductor is a bidirectional 1500W transient voltage suppressor (TVS) diode in DO-201 package, with 160V nominal breakdown voltage (VBR min/max = 144V/176V at IT = 1.0mA), 130V working stand-off voltage (VWM), and 230V maximum clamping voltage (VC) at 6.8A peak impulse current. It protects automotive power-line interfaces against ISO 7637-2 Pulse 1/2a/2b/3a/3b transients.
For engineers reviewing the 1.5KE160CA R0G datasheet, 1.5KE160CA R0G pinout, 1.5KE160CA R0G application, or 1.5KE160CA R0G equivalent, key selection criteria include clamping voltage margin vs. system rail, unidirectional/bidirectional polarity requirement, AEC-Q101 qualification status, thermal derating above 25°C, and DO-201 mechanical compatibility with existing PCB footprints.
Technical Context
This bidirectional TVS operates symmetrically in both polarities, delivering consistent clamping performance regardless of transient polarity-critical for protecting differential buses or AC-coupled signal lines. Its low dynamic impedance ensures rapid voltage limiting during fast-rising transients (≤5.0ns response time), while its 1500W peak pulse power rating at 10/1000μs waveform supports robust surge immunity in harsh environments.
The device meets ISO 7637-2 Pulse 1 (inductive load dump), Pulse 2a/2b (switching transients), and Pulse 3a/3b (capacitive coupling) test profiles, and features <1μA blocking leakage at 130V VWM-enabling low-power standby operation without excessive quiescent current draw.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160CA | DO-214AA (SMB) surface-mount package; same 160V nominal, 230V VC, but lower 600W PPK rating. | Requires PCB redesign for SMT footprint; unsuitable for through-hole legacy designs or high-temperature wave-solder processes. | Select when board space is constrained and thermal management allows lower surge rating. |
| 1.5SMC160CA | DO-214AB (SMC) package; identical 1500W rating and 230V VC, but slightly higher VWM (130V same) and tighter VBR tolerance (±5% vs ±10%). | Same mechanical mounting as DO-201 but larger body; requires verification of clearance/creepage for high-voltage isolation. | Prefer when tighter VBR consistency is needed for precise clamping margin control in safety-critical systems. |

FAQ
What is the clamping voltage of the 1.5KE160CA R0G under standard 10/1000μs surge conditions?
The 1.5KE160CA R0G has a maximum clamping voltage (VC) of 230 V at 6.8 A peak impulse current (IPP), measured using the standardized 10/1000μs double-exponential waveform. This value represents the worst-case overvoltage imposed on protected circuitry during a full-rated 1500W transient event, and is confirmed in the Electrical Specifications table on page 3 of the official Taiwan Semiconductor datasheet O2104.
Is the 1.5KE160CA R0G AEC-Q101 qualified?
Yes, the 1.5KE160CA R0G is AEC-Q101 qualified. The "H" suffix in the ordering code (e.g., 1.5KE160CAH) denotes AEC-Q101 qualification, and the R0G variant includes this qualification per Taiwan Semiconductor's ordering information table on page 4 of datasheet O2104. This validation covers temperature cycling, highly accelerated life testing (HALT), and ESD robustness required for automotive under-hood applications.
How does the bidirectional configuration of the 1.5KE160CA R0G affect its circuit implementation?
The 1.5KE160CA R0G is a bidirectional TVS diode, meaning it functions identically in both polarities with symmetrical VBR (144–176 V) and VC (230 V) characteristics. Unlike unidirectional variants, it has no cathode band marking and can be mounted without orientation concerns-ideal for protecting AC-coupled lines, differential buses, or floating power domains where polarity reversal is possible.
What is the maximum working stand-off voltage (VWM) for the 1.5KE160CA R0G, and why is it important?
The maximum working stand-off voltage (VWM) for the 1.5KE160CA R0G is 130 V. This parameter defines the highest continuous DC or RMS voltage the device can withstand without entering avalanche conduction. It ensures reliable operation in 12V/24V automotive systems with transient margins, prevents unnecessary leakage current, and avoids false triggering during normal operation-critical for low-power always-on circuits.
Does the 1.5KE160CA R0G meet ISO 7637-2 immunity standards, and which pulses are covered?
Yes, the 1.5KE160CA R0G meets ISO 7637-2 immunity requirements for Pulses 1, 2a, 2b, 3a, and 3b as explicitly stated in the FEATURES section of the Taiwan Semiconductor datasheet O2104. This coverage includes load-dump (Pulse 1), inductive switching (Pulse 2a/2b), and capacitive coupling transients (Pulse 3a/3b), making it suitable for direct integration into OEM-compliant automotive electronic control units.
