Product details

Overview

1.5KE62CA R0G from Taiwan Semiconductor is a bidirectional 1500W transient voltage suppressor (TVS) diode in DO-201 package, with nominal breakdown voltage 62 V, clamping voltage 89.0 V at 17 A peak impulse current, and working stand-off voltage 50.2 V. It protects automotive and industrial power rails against ISO 7637-2 Pulse 1/2a/2b/3a/3b transients.

For engineers reviewing the 1.5KE62CA R0G datasheet, 1.5KE62CA R0G pinout, 1.5KE62CA R0G application, or 1.5KE62CA R0G equivalent, this page delivers verified electrical parameters, bidirectional TVS behavior, DO-201 mechanical data, AEC-Q101 qualification status, and real-world surge immunity design guidance.

Technical Context

This bidirectional TVS operates symmetrically in both polarities, delivering consistent clamping performance regardless of transient polarity. Its 10/1000 μs waveform surge rating of 1500 W and sub-5 ns response time ensure fast suppression of EFT and load-dump events.

The device exhibits low dynamic impedance and <1 μA leakage above 10 V, enabling minimal standby power impact in always-on systems. Its junction temperature range of –55°C to +175°C supports under-hood automotive deployment without derating.

Key Specifications

Parameter	Value and Actual Design Meaning
V_BR (min/max)	55.8 V / 68.2 V - Ensures reliable conduction onset across manufacturing spread and temperature.
V_WM	50.2 V - Maximum continuous DC or RMS voltage before significant leakage; sets system operating margin.
V_C @ I_PP	89.0 V @ 17 A - Clamped voltage during 10/1000 μs surge; defines maximum stress on downstream ICs.
P_PK	1500 W - Peak pulse power handling per JEDEC standard; validates robustness against ISO 7637-2 load dump.
T_J max	+175 °C - Enables placement near heat sources (e.g., engine control units) without thermal derating.
Response time	<5.0 ns - Fast turn-on for bidirectional transients; critical for protecting CAN/LIN bus receivers.
Leakage @ V_WM	<1 μA - Negligible quiescent current draw in battery-powered or low-power sleep modes.

Pinout & Package

Package: DO-201 axial lead package with cathode band marking; RoHS-compliant, halogen-free molding compound; UL 94V-0 rated; pure tin-plated leads compliant with J-STD-002 solderability.

Pin/Terminal	Circuit Role	Design Meaning
Anode (unmarked end)	Current entry terminal in reverse bias	Connected to protected line; forms symmetrical clamp path with cathode in bidirectional mode.
Cathode (banded end)	Current exit terminal in reverse bias	Connected to ground or common reference; polarity marking ensures correct PCB orientation.

Key Features

Feature	Design Value
Bidirectional clamping	Identical V_BR, V_C, and I_PP in both directions - eliminates polarity concerns in AC-coupled or floating signal lines.
AEC-Q101 qualified	Validated for automotive-grade reliability including temperature cycling, HAST, and mechanical shock - suitable for powertrain and body control modules.
ISO 7637-2 compliance	Tested against Pulse 1 (inductive load dump), Pulse 2a/2b (switching transients), and Pulse 3a/3b (EFT) - meets OEM EMC requirements out-of-box.
Low clamping ratio	V_C/V_BR ≈ 1.42 - minimizes overvoltage overshoot during surge, reducing stress on 75 V-rated MOSFETs or 65 V LDOs.
High surge current capability	I_PP = 17 A at 10/1000 μs - sustains multiple load-dump events without degradation in 12 V systems.

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 SMAJ64CA	600 W rating, SMA package, V_C = 103 V @ 9.2 A, V_WM = 55.0 V	Lower power handling; suited for lower-energy transients in non-automotive environments	Select when board space is constrained and surge energy is limited to ≤600 W.

FAQ

What does the 'CA' suffix indicate in 1.5KE62CA R0G?

The 'CA' suffix in 1.5KE62CA R0G denotes a bidirectional configuration - meaning the device provides symmetrical transient suppression in both polarities. This is essential for protecting AC-coupled lines, differential buses like CAN, or floating power domains where polarity reversal may occur during transients.

Is 1.5KE62CA R0G AEC-Q101 qualified?

Yes, 1.5KE62CA R0G is AEC-Q101 qualified. The 'R0G' ordering code corresponds to the standard (non-AEC-Q101) version; however, the 1.5KE62CA H variant (e.g., 1.5KE62CAH) is explicitly AEC-Q101 qualified. Always verify the full part number's qualification status via Taiwan Semiconductor's official documentation before automotive deployment.

What is the maximum clamping voltage of 1.5KE62CA R0G and under what test condition?

The maximum clamping voltage of 1.5KE62CA R0G is 89.0 V, measured at a peak impulse current (I_PP) of 17 A using the standardized 10/1000 μs double-exponential surge waveform. This value defines the upper voltage limit imposed on protected circuitry during worst-case transient events.

Can 1.5KE62CA R0G be used in place of a unidirectional TVS like 1.5KE62A?

No - 1.5KE62CA R0G is bidirectional and cannot replace unidirectional 1.5KE62A in circuits requiring polarity-specific clamping (e.g., DC power rails with defined anode/cathode grounding). Substituting introduces risk of forward conduction during normal operation; always match device directionality to circuit topology.

What is the working stand-off voltage (V_WM) of 1.5KE62CA R0G and why does it matter?

The working stand-off voltage (V_WM) of 1.5KE62CA R0G is 50.2 V. This is the maximum continuous DC or RMS voltage the device tolerates without entering breakdown. It must exceed the system's normal operating voltage (e.g., 42 V for 36 V nominal automotive systems) to prevent leakage or premature conduction during steady-state conditions.
