PTV7.5B-M3/85A

Single Zener Diodes Overview

The PTV7.5B-M3/85A is a surface mount power voltage-regulating diode from Vishay General Semiconductor, part of the eSMP series. It features an SMP (DO-220AA) package with a typical height of 1.0 mm. The device provides a nominal Zener voltage of 8.0 V, ranging from 7.5 V to 8.4 V at a test current of 40 mA. It exhibits a maximum dynamic impedance of 4 Ω and a maximum reverse leakage current of 4.0 μA at 4.0 V. Power dissipation reaches 1500 mW at a lead temperature of 75 °C and 600 mW at an ambient temperature of 25 °C. The component supports a maximum junction temperature of 150 °C and operates within a storage range of -65 °C to +150 °C.

Single Zener Diodes Feature Summary

• Very low profile construction suitable for automated placement
• Low Zener impedance for stable regulation performance
• Halogen-free, RoHS-compliant industrial grade material
• Meets MSL level 1 per J-STD-020 standards

Single Zener Diodes Applications

• General purpose voltage regulation circuits
• Industrial equipment protection applications
• Power supply reference voltage generation

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix /85A corresponds to the 10,000-unit reel quantity on 13-inch diameter plastic tape. Confirm compliance requirements including halogen-free status and RoHS directives against project specifications. Ensure thermal management design accounts for derating curves provided in the datasheet to maintain safe operating temperatures under load conditions.

Single Zener Diodes Selection Notes

Select this component when a compact SMP package is required for space-constrained designs. Choose based on the 8.0 V nominal voltage requirement and low impedance characteristics. Consider the 1500 mW power rating capability at elevated lead temperatures for high-power dissipation scenarios. Verify compatibility with standard SMT assembly processes and reflow soldering profiles up to 260 °C.

Single Zener Diodes Part Context

This device belongs to the PTVxxB series of surface mount power voltage-regulating diodes manufactured by Vishay General Semiconductor. The series covers a wide range of Zener voltages from 3.9 V to 36 V. All variants share the same SMP (DO-220AA) mechanical outline and feature the eSMP branding. The M3 suffix indicates compliance with environmental standards and whisker testing requirements.

Single Zener Diodes Replacement Considerations

PTV7.5B-M3/84A offers identical electrical and mechanical specifications but is supplied in 3,000-unit quantities on 7-inch reels.
