Product details
Overview
1N6267A-E3/73 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 6.45 V to 7.14 V breakdown voltage (VBR) at 10 mA, 5.80 V maximum stand-off voltage (VWM), 1000 µA maximum reverse leakage at VWM, 143 A peak pulse current (IPPM), and clamps transients to ≤10.5 V at IPPM. It is used in automotive sensor interfaces and industrial power supply inputs.
For engineers reviewing the 1N6267A-E3/73 datasheet, 1N6267A-E3/73 pinout, 1N6267A-E3/73 application, or 1N6267A-E3/73 equivalent, this page delivers verified electrical parameters, JEDEC 1.5KE package details, clamping performance under 10/1000 µs surge, thermal derating behavior, and direct alternatives with documented differences in breakdown tolerance and leakage.
Technical Context
This unidirectional TVS diode uses a glass-passivated silicon junction optimized for fast transient response (<1 ns) and low incremental clamping resistance. Its 1500 W peak pulse power rating applies to 10/1000 µs waveform pulses at 0.01% duty cycle, with thermal resistance of 15.4 °C/W (junction-to-lead) enabling effective heat dissipation into PCB copper.
The device operates across –55 °C to +175 °C junction temperature range and exhibits a positive temperature coefficient of VBR (+0.057 %/°C), ensuring stable clamping during thermal transients. It complies with JESD 22-B106 (solder dip at 275 °C for 10 s) and meets UL 94 V-0 flammability requirements for its molded epoxy case.
Key Specifications
| Parameter | Value and Actual Design Meaning |

FAQ
What is the breakdown voltage tolerance for 1N6267A-E3/73?
The 1N6267A-E3/73 has a specified breakdown voltage range of 6.45 V to 7.14 V at 10 mA test current, corresponding to a ±5% tolerance around the nominal 6.8 V rating. This tight tolerance ensures predictable clamping onset across production lots and temperature extremes.
Is 1N6267A-E3/73 suitable for automotive applications?
Yes - the 1N6267A-E3/73 is RoHS-compliant and available in AEC-Q101 qualified version (1N6267AHE3_B). Its –55 °C to +175 °C operating range, 1500 W surge rating, and glass-passivated junction meet requirements for engine control units, body electronics, and ADAS sensor modules.
How does the clamping voltage of 1N6267A-E3/73 compare to its breakdown voltage?
At its rated 143 A peak pulse current (10/1000 µs), the 1N6267A-E3/73 clamps to ≤10.5 V. With a maximum VBR of 7.14 V, this yields a clamping ratio of 1.47 - confirming low dynamic impedance and efficient energy diversion without overstressing downstream 5 V logic.
What is the maximum reverse leakage current for 1N6267A-E3/73 at rated VWM?
The 1N6267A-E3/73 specifies a maximum reverse leakage current of 1000 µA at its 5.80 V stand-off voltage (VWM). This value is measured at 25 °C and remains below 5000 µA up to +125 °C, ensuring minimal standby power impact in always-on systems.
Can 1N6267A-E3/73 be used in bidirectional configurations?
No - the 1N6267A-E3/73 is strictly unidirectional. Bidirectional variants use the "CA" suffix (e.g., 1N6267CA). Using 1N6267A-E3/73 in reverse-biased AC applications would result in forward conduction and failure; correct polarity orientation is essential during PCB layout.
