High frequency switching test ©2004 Power-io's high speed test results. High speed is achieved with a strong control signal.	100% of relays are tested at 15 kHz, @ 50% duty cycle, @ 10V or greater control input, at >10mA, and a 10 volt or greater dc load. This generates a PWM switching speed of 33 microseconds "on" and 33 microseconds "off" or 15,000 ons and offs per second. With a strong control input signal, this provides: 15kHz PWM speed in the HDD-06V75 to HDD-6V15 models					100% of relays are tested at 12 - 20 kHz @ 50% duty cycle, @ 8V or greater control input, at >10mA, and a 10 volt or greater dc load. With a strong control input signal, this provides: 20kHz PWM speed in the HDD-06V75E to HDD-2V40E models 16kHz PWM speed in the HDD-6V20E models 12kHz PWM speed in the HDD-9V30E
General
Dielectric strength (input-output-base plate)	2100 Vpk, 1500 Vrms
Capacitance input to output	8 pf
Ambient operating temperature range	-40 to +85°C. Amperage derating curve decreases from full amperage at 40°C to zero amperage at 100°C when a proper heat sink and air flow pattern are in use. Design your application so that you do not exceed 80% of the max amperage at a given temperature in order to anticipate load variations.
Inductive load protection diode -- recommended for all inductive loads, even "slightly" inductive loads	All inductive DC loads require a high speed protective diode across the load. Two recommended choices are: HDD_DIODE = a 2 amp, DO-41 package, 600V reverse voltage, 75ns HDD_DIODE_1000V4A = a 4 amp, DO-201AD package, 1000V reverse voltage, 75ns These diodes are available in the price list shown above.
