SLSOT05C

SLSOT Series Dual Transient Voltage Suppressors Array for ESD Protection General Description Features The SLSOT Series is a dual monolithic voltage z 2 Unidirectional Transil functions suppressor designed to protect components which z Low leakage current: IR max< 20 μA at VRM are connected to data and transmission lines z 300W peak pulse power(8/20μs) against ESD. It clamps the voltage just above the z Transient protection for data lines as per logic level supply for positive transients and to a diode drop below ground for negative transients. It can also work as bidirectional suppressor by Complies with the following standards connecting only pin1 and 2.

Pulse Waveform Fig3.Power Derating Curve Application Note Electrostatic discharge (ESD) is a major cause of failure in electronic systems. Transient Voltage Suppressors (TVS) are an ideal choice for ESD protection. They are capable of clamping the incoming transient to a low enough level such that damage to the protected semiconductor is prevented. Surface mount TVS arrays offer the best choice for minimal lead inductance. They serve as parallel protection elements, connected between the signal line to ground. As the transient rises above the operating voltage of the device, the TVS array becomes a low impedance path diverting the transient current to ground. The tiny SOT-23 package allows design flexibility in the design of high density boards where the space saving is at a premium. This enables to shorten the routing and contributes to hardening against ESD. www.slkormicro.com 3 SLSOT Series SOT-23 mechanical data Dim www.slkormicro.com 4 Millimeters Min TYP Max A 1.00 1.20 1.40 A1 0 0.05 0.10 A2 1.00 1.15 1.30 b 0.35 0.40 0.50 c 0.10 0.15 0.20 D 2.70 2.90 3.10 E 2.40 2.60 2.80 E1 1.40 1.50 1.60 e 0.85 1.00 1.15 e1 1.80 1.90 2.00 L1 0.40 . q 0° 5° 10° S 0.45 0.50 0.55
