Product details
Overview
1N6275A-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 1500 W peak pulse power rating (10/1000 µs), 14.3–15.8 V breakdown voltage at 1.0 mA test current, 12.8 V maximum standoff voltage, 21.2 V clamping voltage at 70.8 A peak pulse current, and operates across –55 °C to +175 °C junction temperature range - deployed in automotive power supply inputs and industrial sensor interface protection.
For engineers reviewing the 1N6275A-E3/54 datasheet, 1N6275A-E3/54 pinout, 1N6275A-E3/54 application, or 1N6275A-E3/54 equivalent, this page delivers verified electrical parameters, thermal derating behavior, clamping performance under surge conditions, RoHS-compliant packaging details, and direct alternative part comparisons for ESD and lightning transient suppression design validation.
Technical Context
This unidirectional TVS diode uses a glass-passivated silicon junction optimized for fast response (<1 ns) and low incremental surge resistance. Its 1500 W peak pulse power rating is defined per 10/1000 µs waveform with 0.01 % duty cycle, and it maintains stable clamping up to 175 °C junction temperature.
The device exhibits a 0.084 %/°C temperature coefficient of breakdown voltage and a typical thermal resistance of 15.4 °C/W (junction-to-lead), enabling reliable operation without external heatsinking in moderate-power transient events. Standoff voltage (12.8 V) and clamping voltage (21.2 V at 70.8 A) define its protection window for 12 V nominal systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VBR | 14.3–15.8 V at 1.0 mA - defines minimum voltage at which clamping initiates; ensures reliable turn-on before damage to downstream 12 V logic or power ICs |
| Standoff Voltage VWM | 12.8 V max - maximum continuous reverse voltage tolerated without significant leakage; compatible with 12 V rail operation |
| Clamping Voltage VC | 21.2 V at 70.8 A IPPM - peak voltage seen by protected circuit during 1500 W transient; limits stress on 24 V tolerant components |
| Peak Pulse Power PPPM | 1500 W (10/1000 µs) - energy-handling capacity for lightning-induced surges or inductive switch-off spikes in automotive/industrial environments |
| Junction Temperature Range | –55 °C to +175 °C - supports under-hood automotive, motor drive, and industrial control applications without derating below ambient |
| Leakage Current ID | 1.0 µA max at VWM - negligible standby power loss and no interference with high-impedance sensor bias networks |
| Thermal Resistance RθJL | 15.4 °C/W - enables direct PCB copper pour conduction cooling; no heatsink required for single-event transients |
Pinout & Package
Package: Axial-leaded DO-201AD (Case Style 1.5KE), molded epoxy body with matte tin-plated leads; RoHS compliant (E3 suffix), commercial grade; 0.968 g unit weight; supplied in 13" paper tape and reel (54 mm carrier pitch, 1400 pcs/reel).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point in forward bias; connected to system ground or low-side reference | Provides low forward voltage drop (≤3.5 V at 100 A) during surge conduction to ground path |
| Cathode | Current exit point in reverse bias; marked with color band; connected to protected line | Defines polarity-sensitive clamping: conducts only when protected line exceeds VBR above ground |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ15A | DO-214AA package (SMB), 1500 W rating, 14.3–15.8 V VBR, but lower IPPM (100 A vs. 70.8 A) and higher VC (24.4 V) | Surface-mount footprint; better suited for space-constrained PCBs but requires thermal pad for equivalent power handling | Select SMBJ15A when board real estate is limited and thermal vias can be added; avoid if axial lead mounting or legacy through-hole compatibility is required. |
| 1.5KE15A | Same DO-201AD package, identical electrical specs (VBR, VWM, VC, PPPM), but base P/N lacks E3/54 tape-and-reel packaging code | No functional difference; differs only in packaging format (bulk vs. 13" reel) and traceability marking | Choose 1.5KE15A for manual prototyping or low-volume hand-soldering; 1N6275A-E3/54 is preferred for automated SMT line integration with verified reel logistics. |
Compared with SMBJ15A, 1N6275A-E3/54 offers lower clamping voltage and axial-leaded mechanical robustness for high-vibration environments; versus 1.5KE15A, it provides guaranteed RoHS compliance, JESD 201 Class 1A whisker resistance, and standardized reel delivery for production scalability.

FAQ
What is the clamping voltage of the 1N6275A-E3/54 under maximum rated surge current?
The 1N6275A-E3/54 has a maximum clamping voltage (VC) of 21.2 V at 70.8 A peak pulse current (IPPM) using the standard 10/1000 µs waveform. This value is measured per JEDEC test conditions and represents the highest voltage imposed on the protected circuit during a full-rated transient event. The 1N6275A-E3/54 maintains this clamping performance across its full operating temperature range.
Is the 1N6275A-E3/54 suitable for automotive applications requiring AEC-Q101 qualification?
No, the 1N6275A-E3/54 is a commercial-grade part (E3 suffix) and not AEC-Q101 qualified. For automotive use, Vishay offers the 1.5KE15AHE3_B variant, which carries the HE3 suffix and explicit AEC-Q101 qualification. The 1N6275A-E3/54 meets all electrical and thermal specifications of the family but lacks the extended reliability testing required for automotive under-hood deployment.
How does the standoff voltage of 1N6275A-E3/54 relate to 12 V system compatibility?
The 1N6275A-E3/54 has a maximum standoff voltage (VWM) of 12.8 V, making it compatible with nominal 12 V DC systems where operating voltages may reach up to 14.5 V during charging. Its 14.3–15.8 V breakdown range ensures activation only during overvoltage events, avoiding false triggering during normal regulation. The 1N6275A-E3/54 thus provides margin between steady-state rail and clamping onset.
What is the thermal resistance from junction to lead for the 1N6275A-E3/54, and why does it matter?
The 1N6275A-E3/54 has a typical junction-to-lead thermal resistance (RθJL) of 15.4 °C/W. This low value allows heat generated during transient conduction to dissipate efficiently into PCB copper pours or chassis connections without requiring external heatsinks. It directly supports reliable single-pulse operation in high-temperature environments and simplifies thermal design for 1N6275A-E3/54-based protection circuits.
Can the 1N6275A-E3/54 be used in bidirectional configurations?
No, the 1N6275A-E3/54 is a unidirectional TVS diode, indicated by the "A" suffix and cathode band marking. Bidirectional variants in this family use the "CA" suffix (e.g., 1.5KE15CA). Using the 1N6275A-E3/54 in a bidirectional application would result in forward conduction during negative transients, potentially damaging the device or failing to protect the circuit. Always verify polarity designation before layout placement of the 1N6275A-E3/54.
