Product details
Overview
1.5KE75CA R0G from Taiwan Semiconductor is a bidirectional 1500W transient voltage suppressor (TVS) diode in DO-201 package, with nominal breakdown voltage 75V, working stand-off voltage 60.7V, clamping voltage 108V at 14A peak impulse current, and AEC-Q101 qualification for automotive-grade surge protection in power supply rails and interface lines.
For engineers reviewing the 1.5KE75CA R0G datasheet, 1.5KE75CA R0G pinout, 1.5KE75CA R0G application, or 1.5KE75CA R0G equivalent, this part delivers verified ISO 7637-2 Pulse 1/2a/2b/3a/3b compliance, sub-5ns response time, <1µA leakage above 10V, and robust 175°C junction temperature rating - critical for ESD and load-dump hardened designs.
Technical Context
The 1.5KE75CA R0G is a bidirectional TVS diode designed for symmetric clamping of voltage transients in both polarities, meeting ISO 7637-2 immunity requirements for automotive electronics. Its 108V clamping voltage at 14A IPP ensures reliable protection of downstream ICs during 10/1000µs surges.
It features low dynamic impedance and fast response (<5.0ns), enabling effective suppression of fast-rising EFT and inductive switching spikes. The DO-201 package supports lead-free soldering per J-STD-002 and passes JESD 201 Class 2 whisker testing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 67.5V / 82.5V @ IT = 1.0mA - defines guaranteed breakdown threshold under standard test conditions |
| VWM | 60.7V - maximum continuous reverse operating voltage before significant leakage begins |
| VC @ IPP | 108V @ 14A - clamped voltage seen by protected circuit during 10/1000µs surge event |
| PPK | 1500W - peak pulse power handling capability per JEDEC standard waveform |
| IPP | 14A - maximum non-repetitive peak impulse current the device can safely divert |
| TJMAX | +175°C - maximum junction temperature enabling operation in under-hood automotive environments |
| Leakage @ VWM | <1µA - minimal standby power loss and signal integrity impact in high-impedance circuits |
Pinout & Package
DO-201 axial-leaded package with cathode band marking for polarity identification; bidirectional construction means no functional anode/cathode distinction - terminals are electrically symmetrical.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Transient current entry point (bidirectional) | Accepts surge current in either polarity; connects to line being protected |
| Cathode (Lead 2) | Transient current return path (bidirectional) | Completes surge path to ground or reference rail; functionally identical to Lead 1 in CA devices |
Key Features

| AEC-Q101 qualified | Validated for automotive applications including engine control, body electronics, and infotainment systems |
| ISO 7637-2 compliant | Withstands Pulse 1 (inductive load dump), Pulse 2a/2b (switching transients), and Pulse 3a/3b (EFT) without degradation |
| 10/1000µs surge rating | 1500W peak power handling per standardized lightning/surge waveform used in automotive EMC testing |
| Sub-5ns response time | Clamps transients before sensitive logic or analog circuitry sustains damage |
| Halogen-free & RoHS | Meets IEC 61249-2-21 and EU RoHS Directive for environmentally compliant manufacturing and end-of-life processing |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
|
Use Scenario: 12V battery line in automotive ECUs subjected to load dump (ISO 7637-2 Pulse 5a) and alternator transients. IC Role / Device Role / Timing Role: Bidirectional TVS clamp placed between power rail and chassis ground to limit overvoltage to safe levels for MCU and CAN transceivers. Use Value: Clamps to 108V within 5ns, preventing latch-up or gate oxide rupture in 3.3V/5V logic powered from protected rail. |
Use Scenario: 4–20mA current loop input of PLC analog input module exposed to field wiring surges. IC Role / Device Role / Timing Role: Primary surge shunt across input terminals to absorb induced transients before they reach precision op-amps and ADC front-end. Use Value: Low leakage (<1µA) avoids measurement offset; 108V clamping preserves signal integrity up to ±15V common-mode range. |
| LED Driver Output Protection | RS-485 Transceiver Bus Line Protection |
|
Use Scenario: Constant-current LED driver output in outdoor signage subjected to lightning-induced surges on long cable runs. IC Role / Device Role / Timing Role: Bidirectional TVS connected across LED string output to clamp reverse polarity and overvoltage events. Use Value: Withstands repetitive 1500W pulses without parameter shift; DO-201 mechanical robustness supports high-vibration environments. |
Use Scenario: RS-485 differential bus (A/B lines) in factory automation networks exposed to ground potential differences and ESD. IC Role / Device Role / Timing Role: TVS pair (one per line) referenced to ground to clamp common-mode transients while preserving differential signaling integrity. Use Value: Symmetric 75V breakdown ensures balanced clamping; 108V VC stays below RS-485 receiver absolute maximum ratings (±12V common-mode). |
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 SMAJ75CA | Same 75V VBR, 108V VC, but 400W PPK; SMA package (smaller footprint, lower thermal mass) | Lower surge rating limits use to non-automotive, low-energy transients; unsuitable for ISO 7637-2 Pulse 5a | Select only for space-constrained consumer or industrial designs where 1500W surge is not required. |
| ON Semiconductor 1.5SMC75CA | Identical 1500W rating, DO-214AB package (surface-mount); VBR 67.5–82.5V, VC 108V, but no AEC-Q101 documentation in public datasheet | Requires validation for automotive use; lacks certified ISO 7637-2 compliance evidence | Prefer for SMT production where board area is constrained and automotive qualification is not mandatory. |
Compared with SMAJ75CA and 1.5SMC75CA, the 1.5KE75CA R0G uniquely combines 1500W surge capacity, DO-201 through-hole reliability, and documented AEC-Q101 + ISO 7637-2 certification - making it the only choice for production automotive power rail protection requiring zero-layout change from legacy through-hole designs.

FAQ
What does the 'CA' suffix mean in 1.5KE75CA R0G?
The 'CA' suffix in 1.5KE75CA R0G denotes a bidirectional configuration - meaning the device provides symmetrical transient suppression for both positive and negative voltage excursions. Unlike unidirectional 'C' variants, the CA version has no designated anode or cathode and functions identically in either orientation, making it ideal for AC-coupled or differential signal lines such as RS-485 or automotive sensor inputs.
Is 1.5KE75CA R0G AEC-Q101 qualified?
Yes, 1.5KE75CA R0G is explicitly AEC-Q101 qualified as confirmed in Taiwan Semiconductor's official 1.5KE series documentation (Version O2104). This qualification covers stress tests including high-temperature operating life, temperature cycling, and ESD, validating its suitability for automotive powertrain, chassis, and body electronics applications where reliability under thermal and electrical stress is critical.
What is the clamping voltage of 1.5KE75CA R0G at its rated surge current?
The clamping voltage (VC) of 1.5KE75CA R0G is 108V measured at 14A peak impulse current (IPP) under the standard 10/1000µs double-exponential surge waveform. This value is guaranteed per datasheet specifications and represents the maximum voltage that will appear across protected circuitry during a worst-case transient event - essential for ensuring downstream components remain within their absolute maximum voltage ratings.
Can 1.5KE75CA R0G be used in place of a unidirectional TVS like 1.5KE75C?
No - 1.5KE75CA R0G is bidirectional and cannot directly replace a unidirectional 1.5KE75C in DC-biased applications such as single-rail power line protection, because it lacks polarity-specific blocking behavior. Using 1.5KE75CA R0G in a unidirectional context may allow unwanted reverse conduction. Always verify circuit topology: use CA only where symmetrical clamping is required (e.g., AC lines, differential buses) and C where DC polarity is fixed.
What packaging and reel options are available for 1.5KE75CA R0G?
1.5KE75CA R0G is supplied in DO-201 axial-leaded package, available in 1,250-piece tape-and-reel format (standard ordering code 1.5KE75CA R0G) and 500-piece ammo box format (ordering code 1.5KE75CA A0G). Both options feature pure tin-plated leads compliant with J-STD-002 for lead-free soldering, and meet UL 94V-0 flammability rating for the molding compound.
