The Diodes Incorporated DESD5V0U1BB-7 is a single-channel low-capacitance bidirectional TVS diode designed to protect sensitive electronics against ESD and transient surge events. It is housed in a compact SOD523 surface-mount package and is intended for portable electronics, communications systems, computers, and peripherals.
The device has a maximum 5V reverse standoff voltage and a breakdown-voltage range of 5.5V to 9.5V, with 7V typical. Under an 8/20µs, 3A surge pulse, the typical clamping voltage is 7.2V, while peak pulse current is rated at 3A.
ESD protection is rated at ±10kV contact discharge according to IEC 61000-4-2. At a 5V reverse voltage, leakage current is 5nA typical and 100nA maximum. Typical dynamic impedance is 0.3Ω under the specified TLP test condition.
Typical channel capacitance is only 2.9pF at 0V and 1MHz, decreasing to approximately 1.9pF at 5V and 1MHz, helping minimize capacitive loading on protected signal lines.
The DESD5V0U1BB-7 has a maximum package power dissipation of 250mW and an operating/storage junction-temperature range of -65°C to +150°C. It is MSL Level 1, lead-free, RoHS compliant, halogen- and antimony-free, and supplied on 7-inch tape-and-reel with 3,000 devices per reel.
