FEATURES
♦ Plastic package has Underwriters Laboratory
Flammability Classification 94V-0
♦ Glass passivated junction
♦ 500W peak pulse power surge capability with a
10/1000µs waveform, repetition rate (duty cycle): 0.01%
♦ Excellent clamping capability

265°C/10 seconds 0.375” (9.5mm) lead length,
5lbs (2.3 kg) tension
MECHANICAL DATA
Case: JEDEC DO-204AC molded plastic body over
passivated junction
Terminals: Solder plated axial leads, solderable per
MIL-STD-750, Method 2026
Polarity: For uni-directional types the color band denotes
the cathode, which is positive with respect to the anode
under normal TVS operation
Mounting Position: Any
Weight: 0.015 ounce, 0.4 gram
DEVICES FOR BIDIRECTIONAL APPLICATIONS
For bi-directional use C or CA Suffix. (e.g. SA5.0C, SA170CA).
Electrical characteristics apply in both directions.
