Product details
Overview
1.5KE180A R0G from Taiwan Semiconductor is a unidirectional 1500W transient voltage suppressor (TVS) diode in DO-201 package, with nominal breakdown voltage 180 V, working stand-off voltage 154 V, clamping voltage 246 V at 6.4 A peak pulse current, and junction temperature range −55 °C to +175 °C. It protects automotive power rails and industrial I/O interfaces against ISO 7637-2 Pulse 1/2a/2b/3a/3b transients.
For engineers reviewing the 1.5KE180A R0G datasheet, 1.5KE180A R0G pinout, 1.5KE180A R0G application, or 1.5KE180A R0G equivalent, this page delivers verified electrical parameters, DO-201 terminal polarity marking, clamping performance under 10/1000 μs surge, leakage behavior at 154 V, and AEC-Q101-compliant alternatives for automotive-grade ESD and load-dump protection.
Technical Context
This unidirectional TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds 171 V (min VBR) at 1 mA test current, it avalanches to limit transient energy. Its low dynamic impedance ensures rapid response (<1 ps from 0 V to VBR) and stable clamping at 246 V under 6.4 A 10/1000 μs surge.
Designed for high-reliability automotive applications, it meets AEC-Q101 stress requirements and ISO 7637-2 immunity standards. The DO-201 package supports lead-free soldering per J-STD-002, withstands 200 A non-repetitive forward surge, and maintains <1 μA leakage above 10 V - critical for low-power standby circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 171 V / 189 V at 1 mA - defines precise avalanche onset window for predictable clamping threshold |
| VWM | 154 V - maximum continuous reverse voltage before leakage exceeds 1 μA, enabling safe operation on 130–150 V DC systems |
| VC @ IPP | 246 V at 6.4 A - peak clamped voltage during 10/1000 μs surge, limiting downstream IC stress to ≤246 V |
| PPK | 1500 W - single-pulse surge power handling capability, derated linearly above 25 °C ambient |
| IFSM | 200 A - non-repetitive forward surge rating (8.3 ms half-sine), supporting inductive load switching without failure |
| TJ max | +175 °C - maximum junction temperature, enabling use in under-hood automotive environments |
| Leakage @ VWM | <1 μA - ultra-low reverse leakage preserves battery life in always-on vehicle modules |
Pinout & Package
DO-201 axial-leaded package with cathode band marking; anode and cathode terminals are identified by polarity band (cathode) on body. Leads are pure tin-plated, solderable per J-STD-002, and meet JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Reverse-biased avalanche node | Connected to protected line; conducts during overvoltage to clamp voltage to VC |
| Anode (unbanded end) | Reference/ground return path | Typically tied to system ground or low-impedance return; completes shunt path for transient current |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive under-hood use including temperature cycling, humidity bias, and mechanical shock |
| 1500 W 10/1000 μs surge rating | Withstands high-energy load dump and alternator transients without degradation |
| Clamping voltage 246 V @ 6.4 A | Ensures protected ICs see ≤246 V during worst-case ISO 7637-2 Pulse 5a events |
| Leakage <1 μA @ 154 V | Minimizes quiescent current draw in battery-powered telematics and sensor modules |
| DO-201 package with UL 94V-0 molding | Enables manual or automated through-hole assembly while meeting flammability safety standards |

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 SMAJ180A | Same DO-214AC (SMA) package; 180 V nominal, 246 V clamping, but rated for 400 W only | Lower surge rating limits use to lower-energy transients (e.g., ESD only); not suitable for ISO 7637-2 Pulse 5a | Select only for space-constrained PCBs where 400 W surge margin suffices and DO-201 footprint is unavailable |
| ON Semiconductor 1.5SMC180A | DO-214AB (SMC) package; identical 180 V VNOM, 246 V VC, 1500 W rating, but AEC-Q101 not documented | Approved for industrial use; lacks automotive qualification evidence required for Tier 1 vehicle programs | Prefer for cost-sensitive industrial designs where AEC-Q101 is not mandated; verify qualification status per batch |
Compared with 1.5KE180A R0G, SMAJ180A offers smaller footprint but sacrifices 73% surge capacity, while 1.5SMC180A matches power rating but lacks AEC-Q101 validation - making 1.5KE180A R0G the sole choice for production automotive systems requiring certified reliability.

What is the breakdown voltage range of the 1.5KE180A R0G?
The 1.5KE180A R0G has a guaranteed breakdown voltage range of 171 V to 189 V at 1 mA test current, measured per ANSI/IEEE C62.35. This tight 10% tolerance ensures consistent clamping behavior across production lots and enables reliable design margining against 180 V nominal systems.
Does the 1.5KE180A R0G meet AEC-Q101 qualification?
Yes, the 1.5KE180A R0G is explicitly AEC-Q101 qualified per Taiwan Semiconductor's documentation (Version O2104). It undergoes stress testing for temperature cycling, high-temperature operating life, and mechanical shock - confirming suitability for automotive under-hood applications.
What is the maximum clamping voltage of the 1.5KE180A R0G under surge conditions?
The 1.5KE180A R0G clamps to a maximum of 246 V when subjected to its rated 6.4 A peak pulse current (IPP) under the standard 10/1000 μs waveform. This value is guaranteed across temperature and lifetime, ensuring downstream components remain within safe voltage limits.
How does the 1.5KE180A R0G differ from the non-A version (1.5KE180 R0G)?
The 1.5KE180A R0G features tighter VBR tolerance (171–189 V vs. 162–198 V for 1.5KE180), lower clamping voltage (246 V vs. 258 V), and full AEC-Q101 qualification - whereas the non-A variant lacks automotive qualification and has wider parametric spread, limiting its use to industrial applications.
What package type and marking does the 1.5KE180A R0G use?
The 1.5KE180A R0G uses the DO-201 axial-leaded package with cathode band marking. Its marking code is "180A" followed by date and factory codes; the "R0G" suffix indicates green compound and tape-and-reel packaging (1250 pcs/reel), compliant with RoHS and halogen-free standards.
