Product details
Overview
1.5KE62A R0G from Taiwan Semiconductor is a unidirectional 1500W transient voltage suppressor (TVS) diode in DO-201 package, with nominal breakdown voltage 62 V, working stand-off voltage 53.0 V, clamping voltage 85.0 V at 18 A peak pulse current, and junction temperature range −55 °C 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 1.5KE62A R0G datasheet, 1.5KE62A R0G pinout, 1.5KE62A R0G application, or 1.5KE62A R0G equivalent, this page delivers verified electrical parameters, DO-201 terminal mapping, AEC-Q101 qualification status, clamping performance under 10/1000 μs transients, and real-world use cases in automotive and industrial power systems.
Technical Context
The 1.5KE62A R0G operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds its 58.9–65.1 V breakdown range at 1 mA test current. It clamps transient energy by shunting >18 A peak impulse current (10/1000 μs) while limiting voltage to ≤85.0 V across the protected node.
Its low dynamic impedance and sub-nanosecond response (<1.0 ps from 0 V to VBR) enable effective suppression of fast ESD and load-dump events. The device meets ISO 7637-2 immunity requirements and supports operation up to 175 °C junction temperature without derating loss.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR @ IT = 1 mA | 58.9–65.1 V - defines precise avalanche initiation threshold for reliable overvoltage triggering |
| VWM | 53.0 V - maximum continuous reverse operating voltage before leakage rises above 1 µA |
| VC @ IPP = 18 A | 85.0 V - clamped voltage during full 1500 W surge, determining downstream component stress margin |
| PPK | 1500 W - peak pulse power handling capability under standardized 10/1000 μs waveform |
| Junction Temp Range | −55 °C to +175 °C - enables deployment in under-hood automotive environments and industrial motor drives |
| Leakage @ VWM | <1 µA - ensures minimal standby power loss and signal integrity in high-impedance circuits |
| Response Time | <1.0 ps - enables suppression of nanosecond-scale ESD and fast transients before IC damage occurs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64A | 64 V VBR, 640 W PPK, SMB package (smaller footprint, lower surge rating) | Lower power handling limits use to sub-1 kW surges; not suitable for ISO 7637-2 Pulse 5a | Select when board space is constrained and peak surge energy is ≤640 W |
| 1.5KE62CA | Bidirectional version, same VBR and PPK, but symmetric clamping in both polarities | Required only for AC-coupled or floating signal lines where polarity reversal may occur | Choose only if bidirectional protection is mandated by circuit topology |
Compared with SMBJ64A, the 1.5KE62A R0G delivers 2.3× higher surge power (1500 W vs. 640 W) and AEC-Q101 qualification - critical for automotive load-dump immunity. Versus 1.5KE62CA, it offers lower capacitance and tighter VC/VBR ratio for unidirectional DC rails, reducing forward conduction losses.

FAQ
What is the breakdown voltage range of the 1.5KE62A R0G?
The 1.5KE62A R0G has a guaranteed breakdown voltage range of 58.9 V to 65.1 V at 1 mA test current (IT), measured per ANSI/IEEE C62.35. This range ensures consistent avalanche triggering across production lots and temperature extremes, supporting reliable overvoltage protection in 12 V and 24 V automotive systems where the 1.5KE62A R0G is commonly deployed.
Is the 1.5KE62A R0G AEC-Q101 qualified?
Yes, the 1.5KE62A R0G is AEC-Q101 qualified - confirmed by Taiwan Semiconductor's official documentation and ordering code suffix "R0G", which denotes AEC-Q101-compliant production. This qualification covers stress tests including high-temperature reverse bias (HTRB), temperature cycling, and ESD (HBM ≥8 kV, CDM ≥1 kV), making the 1.5KE62A R0G suitable for under-hood automotive applications such as engine control units and body control modules.
What is the clamping voltage of the 1.5KE62A R0G at its rated peak pulse current?
The 1.5KE62A R0G clamps to a maximum of 85.0 V at 18 A peak pulse current (IPP) under the standard 10/1000 μs waveform. This value is measured per JEDEC standards and defines the upper voltage limit imposed on protected circuitry during worst-case surge events - a critical parameter for ensuring downstream components like microcontrollers and gate drivers remain within their absolute maximum ratings when the 1.5KE62A R0G is deployed.
Does the 1.5KE62A R0G meet ISO 7637-2 immunity requirements?
Yes, the 1.5KE62A R0G meets ISO 7637-2 immunity requirements for Pulses 1, 2a, 2b, 3a, and 3b - explicitly stated in Taiwan Semiconductor's datasheet. Its 1500 W surge rating, low clamping voltage (85.0 V), and fast response (<1.0 ps) enable compliance with these automotive transient test profiles, confirming the 1.5KE62A R0G's suitability for protecting sensitive electronics in vehicles subjected to battery disconnection, inductive load switching, and ignition noise.
What is the package type and lead finish of the 1.5KE62A R0G?
The 1.5KE62A R0G uses the DO-201 axial package with pure tin-plated leads, fully compliant with J-STD-002 for solderability and JESD 201 Class 2 for whisker resistance. The molding compound meets UL 94V-0 flammability rating, and the cathode is marked by a visible band on the body - all mechanical specifications are documented in the official 1.5KE62A R0G datasheet revision O2104.
