Overview
The LM336Z-2.5#TRPBF is a two-terminal shunt voltage reference diode manufactured by Analog Devices Inc., housed in a 3-lead plastic TO-92 package. It provides a nominal reverse breakdown voltage of 2.49V at a test current of 1mA, with an initial tolerance range of 2.39V to 2.59V for the standard grade. The device features a maximum dynamic impedance of 0.6Ω and operates within a temperature range of 0°C to 70°C.
Feature Summary
- Functions as a general-purpose shunt regulator diode designed for stable operation across a wide operating current range.
- Includes an adjustable terminal that allows users to minimize the temperature coefficient or adjust the reference voltage without altering thermal stability.
- Capable of serving as either a positive or negative voltage reference due to its shunt regulator topology.
Applications
- 8-Bit A/D and D/A Reference
- Digital Voltmeters
- Current Loop Measurement and Control Systems
Procurement Notes
Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing from distributors. Confirm the manufacturer designation matches Analog Devices Inc. rather than legacy sources. Ensure the component meets RoHS compliance standards required for your assembly process before finalizing procurement orders.
Selection Notes
Select this component for applications requiring a low-cost, reliable 2.5V reference in through-hole designs. Consider the LM136 variant if a wider industrial temperature range is necessary. Evaluate the LT1009 datasheet if lower initial tolerance or superior long-term stability specifications are required for high-precision circuits.
Part Context
This part belongs to the LM136/LM336 family of precision shunt regulators. The LM336 series represents the commercial grade version of the original National Semiconductor design, now maintained under the Analog Devices portfolio following industry acquisitions and consolidation.
Replacement Considerations
Consult the LT1009 data sheet for improved performance alternatives offering lower initial tolerance and better long-term stability. The LM136H-2.5 serves as a hermetic metal can alternative for environments requiring higher temperature ranges.
