CAUTIONS FOR USE

1. Regarding output noise surge pro-

tection

A high noise surge voltage applied to the

SSR load circuit can cause malfunction or

permanent damage to the device. If such

a high surge is anticipated, use a varistor

across the SSR output.

2. When used for the load less than rated

An SSR may malfunction if it is used be-

low the specified load. In such an event,

use a dummy resistor in parallel with the

load.

3. Noise and surge protection at the in-

put side

A high noise surge voltage applied to the

SSR input circuit can cause malfunction

or permanent damage to the device. If

such a high surge is anticipated, use C or

R noise absorber in the input circuit.

4. When the input terminals are con-

nected with reverse polarity

Reversing the polarity may cause perma-

nent damage to the device. Take special

care to avoid polarity reversal or use a

protection diode in the input circuit.

5. In the case of operating voltage con-

taining ripple

If the SSR control voltage contains ripple,

the peak of the ripple should not exceed

the maximum rated control voltage. The

bottom of the ripple should exceed the

minimum rated control voltage.

6. Cleaning solvents compatibility

Dip cleaning with an organic solvent is

recommended for removal of solder flux,

dust, etc. Select a cleaning solvent from

the following table. If ultrasonic cleaning

must be used, the severity of factors such

as frequency, output power and cleaning

solvent selected may cause loose wires

and other defects. Make sure these condi-

tions are correct before use. For details,

please consult us.

7. Others

(1) If an SSR is used in close proximity to

another SSR or heat-generating device,

its ambient temperature may exceed the

allowable level. Carefully plan SSR layout

and ventilation.

(2) Soldering to SSR terminals should be

completed within 5 seconds at 260°C.

(3) Terminal connections should be made

by referring to the associated wiring dia-

gram.

(4) For higher reliability, check device

quality under actual operating conditions.

8. Thermal Design

SSRs used in high-reliability equipment

require careful thermal design. In particu-

lar, junction temperature control has a sig-

nificant effect on device function and life

time. The rated load current for board-

mounting SSRs is defined as the maxi-

mum current possible at an ambient tem-

perature of 40°C (30°C) while allowing

natural cooling (self cooling). If the ambi-

ent temperature exceeds 40°C (30°C),

load current derating is necessary ac-

cording to the load current versus ambient

temperature curve. If adjacent devices act

as heat sources, the SSR should be locat-

ed more than 10 mm away from those de-

vices.
