Product details
Overview
1.5KE10A R0G from Taiwan Semiconductor is a unidirectional 1500W transient voltage suppressor (TVS) diode in DO-201 package, with 10V nominal breakdown voltage (VBR = 9.5–10.5V @ 1.0mA), 8.55V working stand-off voltage (VWM), and 14.5V clamping voltage (VC @ 10A). It delivers fast response (<1.0ps), low dynamic impedance, and meets ISO 7637-2 Pulse 1/2a/2b/3a/3b for automotive load-dump and EFT immunity in power rail protection.
For engineers reviewing the 1.5KE10A R0G datasheet, 1.5KE10A R0G pinout, 1.5KE10A R0G application, or 1.5KE10A R0G equivalent, this page provides verified electrical parameters, DO-201 terminal polarity mapping, AEC-Q101 qualification status, clamping performance under 10/1000μs surge, and real-world use cases in automotive ECUs, industrial I/O modules, and DC power supply input stages.
Technical Context
The 1.5KE10A R0G operates as a unidirectional avalanche diode, conducting only when reverse voltage exceeds its VBR threshold (9.5–10.5V), with clamping action limiting transient energy to ≤14.5V at 10A peak impulse current. Its junction temperature range spans –55°C to +175°C, supporting under-hood automotive deployment without derating up to 75°C ambient.
It features pure tin-plated leads compliant with J-STD-002 solderability, UL 94V-0 molding compound, and passes JESD201 Class 2 whisker testing. Polarity is marked by cathode band; no bidirectional operation is supported - confirmed by absence of "C" or "CA" suffix and unidirectional-only test conditions in datasheet.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR @ IT | 9.5–10.5 V @ 1.0 mA - defines precise avalanche onset for reliable overvoltage triggering |
| VWM | 8.55 V - maximum continuous reverse voltage before leakage exceeds 1 µA, ensuring no false conduction during normal 9V system operation |
| VC @ IPP | 14.5 V @ 10 A - clamped voltage during 10/1000µs surge, limiting downstream IC stress to safe margin below 16V logic rails |
| PPK | 1500 W - peak pulse power handling per 1ms non-repetitive event, sufficient for ISO 7637-2 Pulse 5a load dump suppression |
| IPP | 10 A - peak impulse current capability, enabling protection of 12V supply lines against 100V/1Ω transients |
| Junction Temp | –55°C to +175°C - supports placement near heat sources in engine control units without thermal shutdown |
| Leakage @ VWM | <1 µA - negligible standby current draw, critical for always-on automotive modules with battery drain constraints |
Pinout & Package
Package: DO-201 axial leaded case with cathode band marking; body length 9.5 mm, diameter 5.6 mm; RoHS-compliant, halogen-free molding compound rated UL 94V-0.
| Pin/Terminal | Circuit Role | Design Meaning |

| Anode (unmarked end) | Ground reference node | Connected to system ground or low-impedance return path; carries full surge current during clamping |
| Cathode (banded end) | Protected line input | Connected to 12V rail or signal line; reverse-biased during normal operation, avalanches during overvoltage |
Key Features
| Feature | Design Value |
|---|---|
| 1500W surge rating | Enables single-device protection against ISO 7637-2 Pulse 5a (load dump) without parallel stacking |
| <1.0 ps response time | Clamps transients before propagation into sensitive analog front-ends or microcontroller I/O pins |
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, humidity bias, and mechanical shock |

Applications
| Automotive Engine Control Unit (ECU) Power Input | Industrial PLC Digital Input Module |
|---|---|
Use Scenario: 12V battery rail exposed to alternator load dump (up to 120V, 400ms) and ignition coil switching noise. IC Role / Device Role / Timing Role: Primary overvoltage clamp on main power entry, placed upstream of DC-DC converter input. Use Value: Limits rail voltage to ≤14.5V during 10A surge, preventing damage to 16V-rated buck controller and MCU power pins. | Use Scenario: 24V digital input channel subject to inductive kickback from solenoid valves and relay coils. IC Role / Device Role / Timing Role: Front-end transient suppressor on optocoupler input side, before series current-limiting resistor. Use Value: Clamps 500V/100ns spikes to <15V, ensuring optocoupler LED remains within safe forward voltage and lifetime spec. |
| LED Headlamp Driver Power Stage | Telecom DC Power Feeder Protection |
Use Scenario: High-current 12V supply to LED driver ICs in automotive headlamps, where PWM switching induces ringing and back-EMF. IC Role / Device Role / Timing Role: Localized TVS at driver IC VCC pin, adjacent to bulk capacitor. Use Value: Absorbs sub-microsecond ringing peaks without affecting PWM timing integrity or causing false overvoltage shutdown. | Use Scenario: -48V telecom power feed line exposed to lightning-induced surges and hot-swap transients. IC Role / Device Role / Timing Role: Secondary-level protector after primary gas discharge tube, shunting residual energy before DC-DC isolation stage. Use Value: Provides precise 14.5V clamping on secondary 12V output rail, safeguarding isolated controller and monitoring circuitry. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10A | DO-214AA (SMB) package; 10V VBR, 16.7V VC @ 11.7A; 600W rating | Lower surge capacity; surface-mount only; unsuitable for through-hole legacy designs | Select SMBJ10A only when board space is constrained and 600W clamping suffices for target threat level |
| 1N6271A | Same die, identical specs, but obsolete JEDEC part number; no R0G tape-and-reel packaging option | No functional difference; lacks modern green compound (G) and date-code traceability | Prefer 1.5KE10A R0G for new designs requiring RoHS compliance, AEC-Q101 validation, and full traceability |
Compared with SMBJ10A, the 1.5KE10A R0G delivers 2.5× higher surge power (1500W vs. 600W) and axial-leaded DO-201 compatibility for high-reliability through-hole mounting; versus 1N6271A, it adds green compound, AEC-Q101 qualification, and standardized R0G reel packaging for automated assembly.

FAQ
What is the clamping voltage of the 1.5KE10A R0G under standard test conditions?
The 1.5KE10A R0G has a maximum clamping voltage (VC) of 14.5 V at 10 A peak impulse current with a 10/1000 µs waveform. This value is measured per JEDEC standards and ensures predictable voltage limiting during automotive load-dump events. The 1.5KE10A R0G maintains this clamping performance across its full operating temperature range (–55°C to +175°C), with minimal drift due to its 0.073%/°C VBR temperature coefficient.
Is the 1.5KE10A R0G suitable for bidirectional transient suppression?
No, the 1.5KE10A R0G is strictly unidirectional. Its datasheet specifies cathode-band polarity, lists only unidirectional test conditions (e.g., IFSM, VF), and omits bidirectional VBR symmetry data. For bidirectional protection, select 1.5KE10CA R0G or equivalent - the "A" suffix here denotes tighter VBR tolerance, not polarity. The 1.5KE10A R0G must be oriented with cathode toward the protected line.
Does the 1.5KE10A R0G meet AEC-Q101 requirements?
Yes, the 1.5KE10A R0G is AEC-Q101 qualified, as explicitly stated in the product series documentation and ordering code notes (R0G denotes green compound and tape-and-reel packaging compatible with AEC-Q101 certified lots). This qualification covers stress tests including temperature cycling, high-temperature operating life, and mechanical shock - confirming suitability for automotive under-hood applications.
What is the maximum steady-state power dissipation for the 1.5KE10A R0G?
The 1.5KE10A R0G has a steady-state power dissipation (PD) of 5 W at lead temperature (TL) = 75°C with 0.375" (9.5 mm) lead lengths mounted on a 16 mm × 16 mm copper pad. This rating applies only to continuous DC or low-frequency operation - not transient suppression. During surge events, the device relies on its 1500 W peak power rating (PPK) for short-duration energy absorption, not PD.
How does the 1.5KE10A R0G compare to the older 1N6271A in terms of reliability and compliance?
The 1.5KE10A R0G supersedes 1N6271A with enhanced reliability: it uses halogen-free, RoHS-compliant green compound (per IEC 61249-2-21), passes JESD201 Class 2 whisker testing, and carries full AEC-Q101 qualification - whereas 1N6271A lacks documented qualification status and modern environmental compliance. Both share identical electrical specs, but the 1.5KE10A R0G ensures traceable lot control and long-term supply stability absent in the obsolete 1N6271A.
