Product details
Overview
1.5KE75A B0G from Taiwan Semiconductor is a unidirectional 1500W transient voltage suppressor (TVS) diode in DO-201 package, with 75V nominal breakdown voltage (VBR min/max = 71.3V/78.8V at 1mA), 64.1V working stand-off voltage (VWM), and 103V maximum clamping voltage (VC) at 15A peak impulse current. It protects automotive and industrial power rails against ISO 7637-2 Pulse 1/2a/2b/3a/3b transients.
For engineers reviewing the 1.5KE75A B0G datasheet, 1.5KE75A B0G pinout, 1.5KE75A B0G application, or 1.5KE75A B0G equivalent, key selection criteria include clamping performance under 10/1000μs surge, low leakage (<1μA @ 64.1V), AEC-Q101 qualification status, thermal derating above 25°C, and DO-201 mechanical compatibility with high-current PCB layouts.
Technical Context
This unidirectional TVS diode operates as a voltage-clamped shunt protector: it remains high-impedance below VWM (64.1V), triggers avalanche conduction at VBR (71.3–78.8V), and limits transient energy by clamping to ≤103V at 15A IPP. Its fast response (<1.0ps from 0V to VBR) ensures protection before downstream ICs experience overvoltage stress.
Designed for automotive-grade reliability, the 1.5KE75A B0G meets ISO 7637-2 immunity requirements and supports steady-state power dissipation of 5W at TL = 75°C on 16mm × 16mm copper pads. Junction temperature range is –55°C to +175°C, enabling use in under-hood and industrial control environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 64.1 V - Maximum continuous reverse voltage before leakage exceeds 1 μA; defines safe operating margin below clamping threshold. |
| VBR @ IT=1mA | 71.3–78.8 V - Breakdown voltage range at 1mA test current; determines precise turn-on point for transient suppression. |
| VC @ IPP=15A | 103 V - Clamping voltage during 10/1000μs surge; limits peak stress on protected circuitry. |
| PPK | 1500 W - Peak pulse power rating at TA=25°C; defines single-event surge energy handling capability. |
| ID @ VWM | <1 μA - Reverse leakage current at working voltage; ensures minimal standby power loss and signal integrity. |
| TJ max | +175 °C - Maximum junction temperature; enables operation in high-ambient environments like engine compartments. |
| Package | DO-201 - Axial-leaded, epoxy-molded package rated UL 94V-0; supports manual and automated through-hole assembly. |
Pinout & Package
DO-201 package: axial-leaded, cylindrical epoxy body with cathode band marking. Cathode terminal is marked by a colored band; anode is unmarked lead. Leads are pure tin-plated per J-STD-002 for reliable solderability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Transient current sink | Connected to protected line; conducts surge current to ground when voltage exceeds VBR. |
| Anode (unmarked end) | Reference node | Typically tied to system ground or low-impedance return path; completes clamping loop during overvoltage events. |
Key Features

IC Role / Device Role / Timing Role: Secondary-side TVS on DC output rail to suppress common-mode transients coupled from adjacent data cables. Use Value: Maintains <1μA leakage at 64.1V to avoid disrupting 48V/100mA PoE negotiation, while clamping to 103V to protect IEEE 802.3af/at PHY interfaces. |
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 SMAJ75A | Same DO-214AC (SMA) package; lower PPK (400W); VBR 71.3–78.8V; VC = 121V @ 10.6A. | Lower surge rating and higher clamping voltage limit suitability to consumer-grade rather than automotive or industrial 1500W-class protection. | Select when space-constrained SMT layout is required and surge energy is ≤400W. |
| ON Semiconductor 1N6292A | Identical electrical specs and DO-201 package; same VWM/VBR/VC/IPP; manufactured to different process control standards. | No functional difference in circuit behavior; validated for same ISO 7637-2 pulses and AEC-Q101 testing scope. | Drop-in alternative where dual-sourcing or second-source qualification is mandated for production continuity. |
Compared with 1.5KE75A B0G, SMAJ75A offers surface-mount convenience but sacrifices 65% surge power handling and increases clamping voltage by 17.5%, while 1N6292A delivers identical protection performance in the same through-hole form factor-making it ideal for supply chain diversification without design change.

FAQ
What is the clamping voltage of the 1.5KE75A B0G under standard 10/1000μs surge conditions?
The 1.5KE75A B0G clamps to a maximum of 103 V at 15 A peak impulse current (IPP) under the standardized 10/1000μs double-exponential waveform. This value is measured per JEDEC test conditions and guarantees that protected downstream components see no more than 103 V during surge events, provided layout minimizes parasitic inductance in the clamping path.
Is the 1.5KE75A B0G AEC-Q101 qualified?
Yes, the 1.5KE75A B0G is AEC-Q101 qualified. The "A" suffix in the part number denotes compliance with the AEC-Q101 stress test standard for discrete semiconductors, including high-temperature operating life, temperature cycling, and humidity bias testing-making it suitable for automotive powertrain and chassis applications.
What does the "B0G" suffix indicate in 1.5KE75A B0G?
The "B0G" suffix in 1.5KE75A B0G specifies packaging and environmental compliance: "B" indicates tape-and-reel packaging (1,250 pcs per reel), "0" is a revision code, and "G" denotes halogen-free construction per IEC 61249-2-21. It does not affect electrical specifications or qualification status.
How does the 1.5KE75A B0G compare to bidirectional variants like 1.5KE75CA?
The 1.5KE75A B0G is unidirectional and intended for DC line-to-ground protection, whereas 1.5KE75CA is bidirectional for AC or differential-line applications. The 1.5KE75A B0G has a cathode band marking and forward voltage (~3.5 V at 50 A), while 1.5KE75CA exhibits symmetrical clamping in both directions and lacks polarity marking-making them non-interchangeable without circuit redesign.
What is the maximum steady-state power dissipation for the 1.5KE75A B0G at elevated temperatures?
The 1.5KE75A B0G has a steady-state power dissipation (PD) rating of 5 W at lead temperature TL = 75°C, mounted on a 16 mm × 16 mm copper pad. Derating follows Fig.2 in the datasheet: PD decreases linearly to zero at +175°C junction temperature, requiring thermal analysis for continuous operation above 75°C ambient.
