NXP Semiconductors BZA862AVL,115

Overview

BZA862AVL from Nexperia is a quadruple low-capacitance ESD suppressor diode in SOT353 (SC-88A) package, configured as common-anode for 4-line transient suppression. It delivers 6.2 V working voltage (IZ = 1 mA), ≤100 nA reverse leakage at 4 V, and 9–12 pF capacitance at 5 V reverse bias - enabling high-speed data line protection in USB, HDMI, and audio interfaces.

For engineers reviewing the BZA862AVL datasheet, BZA862AVL pinout, BZA862AVL application, or BZA862AVL equivalent, key selection criteria include clamping performance under IEC 61000-4-2 contact discharge (≥15 kV), differential resistance (≤150 Ω), thermal resistance (185 K/W all-diodes loaded), and compatibility with 5-lead SOT353 PCB footprints.

Technical Context

The BZA862AVL integrates four monolithic Zener-type ESD protection diodes sharing a single anode terminal (Pin 2), forming a compact common-anode array optimized for bidirectional transient clamping on signal lines. Each cathode (Pins 1, 3–5) connects independently to protected I/O paths while referencing the shared anode to ground or supply rail.

Its design targets low-capacitance signal integrity preservation: typical diode capacitance is 18 pF at 0 V and drops to 9–12 pF at 5 V reverse bias, minimizing signal distortion in high-frequency interfaces. Clamping is validated per IEC 61000-4-2 (contact discharge ≥15 kV) and HBM (≥10 kV), with non-repetitive peak reverse current rated at 0.85 A (tp = 1 ms).

FAQ

What is the working voltage range of the BZA862AVL?

The BZA862AVL has a specified working voltage (V_Z) range of 5.89 V to 6.51 V at test current I_Z = 1 mA. This range ensures reliable clamping onset above typical 3.3 V and 5 V logic rails while maintaining sufficient margin against normal operating voltages - critical for preventing false triggering during signal swings in interfaces like USB or I²C.

How does the common-anode configuration of the BZA862AVL affect circuit implementation?

The BZA862AVL's common-anode configuration (Pin 2) requires connection to a stable reference - typically ground for unidirectional clamping or V_CC for bidirectional protection. This architecture enables simultaneous suppression across four independent lines (Pins 1, 3–5) with matched dynamic characteristics, eliminating inter-diode timing variation and simplifying PCB routing versus discrete solutions.

What is the maximum reverse capacitance of the BZA862AVL at 5 V bias?

The BZA862AVL exhibits a maximum diode capacitance of 12 pF at 5 V reverse bias and 1 MHz frequency, with typical value at 9 pF. This low, voltage-dependent capacitance minimizes signal attenuation and phase shift in high-speed data paths - a key enabler for its use in USB 2.0 and HDMI DDC applications where impedance matching and eye diagram integrity are essential.

Can the BZA862AVL withstand multiple ESD strikes without degradation?

Yes, the BZA862AVL is rated for ≥15 kV contact discharge per IEC 61000-4-2 and ≥10 kV per HBM MIL-Std 883. Its monolithic construction and thermal design (R_{th j-a} = 410 K/W) allow dissipation of transient energy without permanent parameter shift - provided PCB layout follows Nexperia's guidelines (short traces, direct ground return, localized copper pour) to avoid localized heating.

Is the BZA862AVL RoHS compliant and halogen-free?

Yes, the BZA862AVL complies with RoHS Directive 2011/65/EU and is halogen-free per Nexperia's standard product specifications. The device uses lead-free solderable terminations and meets JEDEC J-STD-020 moisture sensitivity level (MSL) 1, supporting standard reflow profiles without preconditioning.
