Germanium Diode Spice Model

Varying this 10k value may require adjusting the series resistor of the schottky diodes to match germanium diode response. For eg we can assume the standard value of 11 ev while its 07 ev for schottky diode and 067 ev for germanium diodes.

Germanium diode spice model. Consult the manufacturers web site. I have found several online libraries of spice models for diodes but none of them have the 1n270. Find ltspice germanium diodes related suppliers manufacturers products and specifications on globalspec a trusted source of ltspice germanium diodes information.

Spice modeling of a diode from datasheet. A fallback strategy is to build a spice model from those parameters listed on the data sheet. If you do not find the spice model you need please click o the spice model request button below and fill in all the fields.

The tuner diode and schottky diode ranges use a standard spice diode model and a typical file appears as follows. A google search didnt find it although i found a couple of postings where the author used a model for 1n270 so i think it must exist somewhere. Simulating a silicon diode with a dc sweep and plotting the graph is no problem.

I only have the free version of pspice and it does not have germanium diodes. Spice models for diodes. Table below lists the model parameters for some selected diodes.

I can edit the properties of a. Spice models request form. Zetex zc830a spice model v10 last revised 4392.

Does anyone have the spice model for the 1n270 germanium diode. The feedback resistor is 100 kohm for a x10 gain of the opamp. Diodes incorporated is currently developing spice models for many of our products.

Pspice model library includes parameterized models such as bjts jfets mosfets igbts scrs discretes operational amplifiers optocouplers regulators and pwm controllers from various ic vendors. The series resistor value required to match germanium diode response in this case is 250 ohms. Hello everyone i am trying to simulate the germainium diode characteristics in pspice.

The easiest approach to take for a spice model is the same as for a data sheet.
