LM136H-5.0

Overview

The LM136H-5.0 is a precision 5.0V shunt voltage reference diode manufactured by Texas Instruments. It operates as a fixed voltage reference with an initial accuracy of ±2% and a maximum output current of 10 mA. The device features a low temperature coefficient, ensuring stable performance across its operating range. It is housed in a 3-pin TO-46 metal can package, designed for through-hole mounting. The component functions within a minimum input voltage of 4.9 V and a maximum input voltage of 5.1 V, supporting a load regulation of 20 mV.

Feature Summary

• Precision 5.0V fixed voltage reference operation
• Low temperature coefficient for thermal stability
• Monolithic IC construction for reliability

Applications

• Precision analog circuits requiring stable reference voltages
• Shunt regulator applications
• Test and measurement equipment

Procurement Notes

Verify the specific suffix (e.g., /883 or QML) against project requirements, as these indicate military or aerospace qualification standards distinct from the standard commercial grade. Confirm the package type matches the PCB footprint, as the TO-46 metal can differs significantly from plastic packages like TO-92 used in other series members. Ensure input voltage constraints are respected to maintain regulation.

Selection Notes

Select this component when a hermetically sealed metal package is required for harsh environments or high-reliability applications. Compare the ±2% initial accuracy against tighter tolerance needs; if higher precision is necessary, consider the LM136A variant. Verify that the 10 mA output current capability meets the circuit's biasing requirements without exceeding the device's power dissipation limits in the TO-46 package.

Part Context

The LM136H-5.0 belongs to the LM136/LM236/LM336 family of 5.0V reference diodes. While sharing core electrical characteristics, the 'H' designation typically denotes the TO-46 metal can package, distinguishing it from plastic package variants like the LM336Z. This family provides a cost-effective solution for precision voltage referencing in industrial and commercial systems.

Replacement Considerations

LM136H-5.0/NOPB is a lead-free version of the same device. LM136-5.0MD8 is a die variant. Cross-reference with LM236H-5.0 or LM336H-5.0 for extended temperature ranges or different accuracy grades within the same package.
