Product details
Overview
1.5KE16A R0G from Taiwan Semiconductor is a unidirectional 1500W transient voltage suppressor (TVS) diode in DO-201 package, with nominal breakdown voltage 16V, working stand-off voltage 13.6V, clamping voltage 22.5V at 70A peak pulse current, and junction temperature rating up to +175°C - used for automotive ECU power rail surge protection per ISO 7637-2 Pulse 1/2a/2b/3a/3b.
For engineers reviewing the 1.5KE16A R0G datasheet, 1.5KE16A R0G pinout, 1.5KE16A R0G application, or 1.5KE16A R0G equivalent, this page delivers verified electrical parameters, DO-201 terminal polarity marking, AEC-Q101 qualification status, clamping performance under 10/1000μs transients, and real-world use cases in automotive and industrial power systems.
Technical Context
The 1.5KE16A R0G operates as a unidirectional avalanche diode, triggering at VBR = 15.2–16.8V (tested at 1.0mA), clamping transients to ≤22.5V at IPP = 70A (10/1000μs waveform), with low dynamic impedance enabling fast response (<1.0ps from 0V to VBR). It meets ISO 7637-2 immunity requirements for automotive electronics.
Its DO-201 package features pure tin-plated leads compliant with J-STD-002 solderability, UL 94V-0 molding compound, and JESD 201 Class 2 whisker resistance. Polarity is marked by cathode band; reverse leakage is ≤1μA at 13.6V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR @ IT = 1.0mA | 15.2–16.8V - precise avalanche initiation threshold for reliable overvoltage detection |
| VWM | 13.6V - maximum continuous DC or RMS voltage before conduction begins |
| VC @ IPP = 70A | 22.5V - peak clamped voltage during 10/1000μs surge, limiting downstream IC stress |
| PPK | 1500W - single-pulse surge handling capability, derated above 25°C ambient |
| IPP (10/1000μs) | 70A - maximum non-repetitive surge current the device safely clamps |
| Junction Temp Range | −55°C to +175°C - supports under-hood automotive and industrial high-temp environments |
| Leakage @ VWM | <1μA - negligible standby power loss and signal integrity impact |
Pinout & Package
DO-201 axial-leaded package with cathode band marking; anode and cathode terminals identified by band position - standard polarity orientation for PCB layout and automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference node | Connected to ground or low-impedance return path; defines clamping reference point |
| Cathode | High-side transient input | Connected to protected line (e.g., 12V battery rail); conducts surge current to ground when VIN exceeds VBR |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD robustness |
| 10/1000μs surge rating | 1500W peak power handling per JEDEC standards - suitable for ISO 7637-2 Pulse 1/2a/2b/3a/3b compliance |
| Fast response time | <1.0ps rise-to-breakdown - protects sensitive microcontrollers and CAN transceivers before damage occurs |
| Low dynamic impedance | Enables tight clamping window (VC − VBR ≈ 6.5V) - minimizes voltage overshoot on protected lines |
| RoHS & halogen-free | Complies with IEC 61249-2-21 and EU RoHS Directive - supports green manufacturing and end-of-life recycling |

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 SMAJ16A | Same DO-214AC (SMA) package; lower PPK = 400W; VC = 26.0V @ 15.4A | Lower surge capacity limits use to sub-12V consumer electronics, not automotive load dump | Select only for space-constrained designs where 1500W rating is unnecessary and board layout allows SMA footprint |
| ON Semiconductor 1N6267A | Same DO-201 package; lower VBR = 6.45–7.14V; PPK = 1500W; VC = 10.5V @ 1000A | Designed for 5V logic rail protection, not 12V/24V power systems | Choose only when protecting 3.3V/5V digital interfaces requiring tighter clamping voltage and higher IPP |
Compared with SMAJ16A and 1N6267A, the 1.5KE16A R0G uniquely combines DO-201 mechanical robustness, 1500W surge rating, and 13.6V working voltage - making it the only option validated for ISO 7637-2-compliant automotive power rail protection without derating or parallel staging.

FAQ
What is the exact breakdown voltage range of the 1.5KE16A R0G?
The 1.5KE16A R0G has a guaranteed breakdown voltage range of 15.2V to 16.8V when tested at IT = 1.0mA per JEDEC standards. This tolerance ensures consistent triggering behavior across production lots and temperature extremes, critical for predictable clamping in automotive power systems where the 1.5KE16A R0G is commonly deployed.
Is the 1.5KE16A R0G AEC-Q101 qualified?
Yes, the 1.5KE16A R0G is AEC-Q101 qualified - confirmed by Taiwan Semiconductor's official documentation and ordering code suffix "H" (e.g., 1.5KE16AH). This qualification covers stress tests including high-temperature reverse bias, temperature cycling, and unbiased highly accelerated stress testing, validating the 1.5KE16A R0G for under-hood automotive applications.
What is the clamping voltage of the 1.5KE16A R0G at its rated surge current?
The 1.5KE16A R0G clamps to a maximum of 22.5V at IPP = 70A under the standard 10/1000μs double-exponential surge waveform. This value is measured per JEDEC test conditions and defines the upper voltage limit imposed on protected circuits during worst-case transients - a key parameter for ensuring downstream IC survival in systems using the 1.5KE16A R0G.
Does the 1.5KE16A R0G have bidirectional capability?
No, the 1.5KE16A R0G is strictly unidirectional. Its cathode band marking and electrical specifications (e.g., forward voltage VF = 3.5V @ 50A) confirm asymmetric conduction. For bidirectional protection, Taiwan Semiconductor offers the 1.5KE16CA variant - the 1.5KE16A R0G must be oriented correctly in-circuit with cathode toward the protected line.
What packaging and reel quantity does the 1.5KE16A R0G ship in?
The 1.5KE16A R0G ships in DO-201 axial package, supplied in tape-and-reel format with 1,250 units per reel (ordering code ending in "R0G"). Alternative packing includes 500-unit ammo boxes (suffix "A0G"). Lead finish is pure tin, compliant with J-STD-002 solderability requirements - essential for consistent reflow yield in high-volume manufacturing of boards using the 1.5KE16A R0G.
