Product details
Overview
1.5KE62A B0G 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 rating up to +175°C. It protects automotive power rails and industrial I/O interfaces against ISO 7637-2 Pulse 1/2a/2b/3a/3b transients.
For engineers reviewing the 1.5KE62A B0G datasheet, 1.5KE62A B0G pinout, 1.5KE62A B0G application, or 1.5KE62A B0G equivalent, key selection criteria include clamping performance under 10/1000 μs surge, low leakage (<1 µA above 10 V), AEC-Q101 qualification status, thermal derating behavior, and DO-201 mechanical compatibility with high-current PCB layouts.
Technical Context
This unidirectional TVS diode operates as a voltage-clamped shunt protector, triggering when transient voltage exceeds its 58.9–65.1 V breakdown range at 1 mA test current. Its low dynamic impedance ensures rapid energy diversion during 10/1000 μs surges, limiting downstream voltage to ≤85.0 V at 18 A.
Designed for automotive-grade reliability, it meets ISO 7637-2 immunity requirements and supports steady-state power dissipation of 5 W at 75°C lead temperature. The device exhibits a temperature coefficient of 0.104 %/°C for VBR, enabling predictable clamping shift across -55°C to +175°C operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR @ IT = 1 mA | 58.9–65.1 V - defines precise conduction onset for accurate overvoltage thresholding |
| VWM | 53.0 V - maximum continuous reverse voltage before leakage rises significantly |
| VC @ IPP = 18 A | 85.0 V - clamped voltage during worst-case 10/1000 μs surge, protecting downstream ICs |
| PPK | 1500 W - peak surge power handling capability per single non-repetitive event |
| IPP max | 18 A - maximum peak impulse current supported without degradation |
| Junction temp. (TJ) | -55°C to +175°C - enables deployment in under-hood automotive and industrial environments |
| Leakage @ VWM | <1 µA - minimizes standby power loss and avoids false triggering in high-impedance circuits |
Pinout & Package
Package: DO-201 axial-leaded through-hole package with cathode band marking; tin-plated leads compliant with J-STD-002 solderability; UL 94V-0 molding compound; weight ≈0.090 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward conduction | Connected to protected line side; conducts only during positive surges in unidirectional configuration |
| Cathode | Current exit point during reverse-biased clamping | Connected to ground or low-impedance return path; carries full surge current during transient suppression |
Key Features
| Feature | Design Value |
|---|---|
| Surge rating | 1500 W at 10/1000 μs waveform - handles automotive load-dump and inductive switching events |
| Clamping ratio | VC/VBR ≈ 1.30 - tight voltage control preserves margin for 60 V-rated downstream components |
| Response time | <1.0 ps from 0 V to VBR - faster than most ESD diodes, critical for sub-nanosecond edge transients |
| AEC-Q101 qualification | Available in H-suffix variants - validated for automotive electronics per stress-test requirements |
| Thermal robustness | 175°C max junction temperature - supports operation near hot engine compartments or power converters |
Applications
| Automotive Power Rail Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Suppresses load-dump transients on 12 V battery-fed ECUs per ISO 7637-2 Pulse 5a. IC Role / Device Role / Timing Role: Unidirectional shunt TVS placed between battery rail and ground, clamping surges within 1 ns. Use Value: Limits voltage to ≤85.0 V during 1500 W events, preventing damage to 60 V-rated DC-DC controllers and CAN transceivers. | Use Scenario: Shields 24 V digital input modules from inductive kickback when switching solenoids or relays. IC Role / Device Role / Timing Role: Standoff protection element connected across input terminals, conducting only during overvoltage. Use Value: Withstands 18 A peak impulse current while maintaining <1 µA leakage at 24 V nominal, ensuring signal integrity during normal operation. |
| Lighting System Surge Suppression | ESD-Sensitive Sensor Interface Protection |
Use Scenario: Guards LED driver inputs against ISO 7637-2 Pulse 1 (inductive switch-off) and Pulse 2b (battery disconnect). IC Role / Device Role / Timing Role: Primary clamping device on main power feed, sized for 1500 W single-event tolerance.

IC Role / Device Role / Timing Role: Secondary-level TVS placed after connector, complementing primary ESD diodes. Use Value: Low dynamic impedance ensures fast clamping response (<1 ps), reducing voltage overshoot that could latch or damage precision op-amps. |
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 SMAJ60A | DO-214AC (SMA) package, 60 V VBR min, 87.1 V VC @ 17.2 A, 400 W PPK | Lower surge rating and different footprint - suitable for space-constrained consumer designs, not automotive load-dump | Select when board area is limited and peak surge energy is ≤400 W; requires layout change due to SMD package. |
| ON Semiconductor 1.5SMC62A | SMB package, same 62 V nominal, 85 V VC @ 17.6 A, but rated for 1500 W with different thermal derating curve | Surface-mount alternative with comparable clamping but lower thermal mass - better for reflow assembly, less suited for high-temperature ambient | Choose for automated SMT production where DO-201 through-hole is impractical; verify thermal relief pad design for 175°C operation. |
Compared with 1.5KE62A B0G, SMAJ60A offers smaller size but sacrifices 60% surge capacity and automotive qualification; 1.5SMC62A matches clamping performance and power rating but shifts to SMB package, altering thermal management and assembly process requirements.

FAQ
What is the breakdown voltage range of the 1.5KE62A B0G?
The 1.5KE62A B0G has a guaranteed breakdown voltage range of 58.9 V to 65.1 V at 1 mA test current, measured per JEDEC standard. This range ensures consistent clamping onset across production lots and supports reliable overvoltage thresholding in 12 V and 24 V systems. The nominal 62 V rating reflects the midpoint of this specification window, and the 1.5KE62A B0G maintains this tolerance under specified thermal conditions.
Is the 1.5KE62A B0G AEC-Q101 qualified?
The 1.5KE62A B0G itself is not AEC-Q101 qualified; qualification applies only to variants marked with the "H" suffix (e.g., 1.5KE62AH). The "B0G" suffix indicates green compound and ammo box packaging, not automotive stress testing. For AEC-Q101 compliance, specify 1.5KE62AH or confirm qualification status via Taiwan Semiconductor's official documentation before use in automotive safety-critical applications.
What is the maximum clamping voltage of the 1.5KE62A B0G under surge conditions?
The 1.5KE62A B0G 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 at TA = 25°C and represents the upper limit of voltage seen by downstream circuitry during worst-case transient events. The 1.5KE62A B0G achieves this clamping performance while maintaining low dynamic impedance and sub-nanosecond response time.
Can the 1.5KE62A B0G be used in bidirectional configurations?
No - the 1.5KE62A B0G is a unidirectional TVS diode, intended for use with defined polarity (cathode to ground). Bidirectional operation requires CA-suffix parts such as 1.5KE62CA. Using the 1.5KE62A B0G in reverse-biased AC applications risks permanent failure due to forward conduction during negative half-cycles. Always match the 1.5KE62A B0G polarity to system grounding architecture.
What is the thermal derating behavior of the 1.5KE62A B0G above 25°C ambient?
The 1.5KE62A B0G follows a linear derating curve: peak pulse power decreases from 1500 W at 25°C ambient to zero at 175°C junction temperature. Derating is defined per Figure 2 in the datasheet, with distinct curves for "with heat sink" and "without heat sink" mounting. At 75°C ambient, the 1.5KE62A B0G supports full 1500 W only if mounted on a 16 mm × 16 mm copper pad; otherwise, steady-state power must be limited to 5 W.
