Product details
Overview
1.5KE62CA B0G from Taiwan Semiconductor is a bidirectional 1500W transient voltage suppressor (TVS) diode in DO-201 package, with 62V nominal breakdown voltage (VBR min 55.8V, max 68.2V at 1mA), 50.2V working stand-off voltage (VWM), and 89.0V maximum clamping voltage (VC) at 17A peak pulse current. It protects automotive and industrial power rails against ISO 7637-2 Pulse 1/2a/2b/3a/3b transients.
For engineers reviewing the 1.5KE62CA B0G datasheet, 1.5KE62CA B0G pinout, 1.5KE62CA B0G application, or 1.5KE62CA B0G equivalent, this page delivers verified electrical parameters, bidirectional clamping behavior, AEC-Q101 qualification status, DO-201 mechanical data, and real-world ESD/inductive-spike protection use cases - all confirmed from Taiwan Semiconductor's official O2104 specification document.
Technical Context
This bidirectional TVS diode operates symmetrically in both polarities, delivering consistent clamping performance regardless of transient polarity. Its low dynamic impedance and sub-5ns response time ensure rapid suppression of fast-rising transients such as EFT and load dump spikes.
Designed for rugged environments, it meets ISO 7637-2 immunity requirements and supports junction temperatures from –55°C to +175°C. The device uses silicon avalanche technology with a temperature coefficient of VBR at 0.104%/°C, enabling stable overvoltage protection across wide thermal ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR @ IT = 1mA | 55.8–68.2V: Ensures reliable turn-on within defined tolerance before damaging overvoltage occurs |
| VWM | 50.2V: Maximum continuous DC or RMS voltage the device blocks without leakage exceeding 1µA |
| VC @ IPP = 17A | 89.0V: Clamped voltage seen by protected circuit during 10/1000µs surge - defines worst-case stress level |
| PPK | 1500W: Peak pulse power handling capability under standardized 10/1000µs waveform |
| Response Time | <5.0ns (bidirectional): Time from 0V to VBR onset - critical for suppressing nanosecond-scale EFT events |
| Junction Temp Range | –55°C to +175°C: Enables deployment in under-hood automotive and industrial power supply applications |
| Leakage Current ID | <1µA @ VWM: Minimizes standby power loss and avoids false triggering in high-impedance circuits |
Pinout & Package
Package: DO-201 axial lead package with cathode band marking (not applicable for bidirectional types; polarity is symmetrical). Leads are pure tin-plated, solderable per J-STD-002, and meet JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional avalanche junction | No functional polarity - either terminal serves as anode or cathode depending on transient direction |
| Lead 1 / Lead 2 | Current path terminals | Low-inductance axial leads optimized for transient energy diversion to ground or rail |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Identical VBR and VC in both directions - eliminates need for polarity-aware layout in DC bus protection |
| AEC-Q101 qualified | Validated for automotive electronics per stress test requirements - supports ASIL-B system integration |
| ISO 7637-2 compliance | Tested against Pulse 1 (inductive switch-off), Pulse 2a/2b (battery disconnect), and Pulse 3a/3b (EFT) - ready for OEM ECU designs |
| Halogen-free & RoHS | Meets IEC 61249-2-21 and EU RoHS directives - compliant for global industrial and automotive shipments |
| DO-201 mechanical robustness | UL 94V-0 molding compound and 0.090g mass - withstands vibration, thermal cycling, and reflow soldering |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64CA | Lower PPK (600W), smaller SMB package, VBR 57.6–64.0V, VC = 103V @ 5.8A | Not rated for ISO 7637-2 Pulse 1; limited to lower-energy transients | Select when space-constrained PCB layout prioritizes footprint over surge margin |
| 1.5SMC68CA | Same 1500W rating, SMC package, VBR 61.2–74.8V, VC = 110V @ 13.6A, no AEC-Q101 listing | Lacks automotive qualification; higher clamping voltage reduces protected IC margin | Choose for cost-sensitive industrial applications where AEC-Q101 is not mandated |
Compared with 1.5KE62CA B0G, SMBJ64CA offers compact size but sacrifices surge capacity and automotive compliance, while 1.5SMC68CA matches power rating but trades clamping performance and qualification for surface-mount convenience - making 1.5KE62CA B0G optimal for high-reliability 24V/48V DC systems requiring proven AEC-Q101 and ISO 7637-2 immunity.

FAQ
What does the "CA" suffix indicate in 1.5KE62CA B0G?
The "CA" suffix in 1.5KE62CA B0G denotes a bidirectional configuration - meaning the device provides symmetrical transient suppression in both voltage polarities. This eliminates polarity concerns during placement and enables protection of AC-coupled or floating DC lines. Unlike unidirectional variants (e.g., 1.5KE62A), the CA version has identical breakdown and clamping characteristics in either direction, as confirmed in Taiwan Semiconductor's O2104 datasheet Section "Devices for Bipolar Applications".
Is 1.5KE62CA B0G AEC-Q101 qualified?
Yes, 1.5KE62CA B0G is AEC-Q101 qualified, as explicitly stated in the "FEATURES" section of the official Taiwan Semiconductor 1.5KE series datasheet (Version O2104). This qualification validates its reliability for automotive electronic control units, including temperature cycling, humidity testing, and mechanical shock per the AEC-Q101 standard - making it suitable for engine control, body electronics, and ADAS subsystems.
What is the maximum clamping voltage of 1.5KE62CA B0G at rated surge current?
The maximum clamping voltage (VC) of 1.5KE62CA B0G is 89.0V at a peak pulse current (IPP) of 17A, measured under the standardized 10/1000µs waveform. This value is specified in the Electrical Specifications table on page 3 of the O2104 datasheet and defines the upper voltage limit imposed on protected circuitry during worst-case transient events - critical for ensuring compatibility with 36V or 48V-rated downstream components.
Does 1.5KE62CA B0G meet ISO 7637-2 immunity standards?
Yes, 1.5KE62CA B0G meets ISO 7637-2 immunity requirements for Pulses 1, 2a, 2b, 3a, and 3b, as documented in the "FEATURES" list of the Taiwan Semiconductor 1.5KE series datasheet (O2104). This certification confirms its suitability for protecting automotive electronics against real-world transients including load dump, battery disconnection, and electrical fast transients - essential for Tier 1 supplier compliance and OEM validation.
What is the package type and lead finish of 1.5KE62CA B0G?
1.5KE62CA B0G uses the DO-201 axial lead package with pure tin-plated leads, compliant with J-STD-002 for solderability. The molding compound meets UL 94V-0 flammability rating, and the device passes JESD 201 Class 2 whisker testing. These mechanical attributes - detailed in the "MECHANICAL DATA" section of the O2104 datasheet - ensure robustness in automated assembly, thermal cycling, and long-term field operation.
