Nexperia USA Inc. PESD2CANFD27V-QBZ

Overview

PESD2CANFD27V-QBZ from Nexperia is a dual-channel automotive-grade ESD protection diode in DFN1110D-3 (SOT8015) package, designed for bidirectional transient suppression on CAN-FD and CAN bus lines. It delivers 27 V reverse standoff voltage, 33 V clamping at 1 A, 6 pF capacitance, 20 kV IEC 61000-4-2 ESD rating, and AEC-Q101 qualification for under-hood vehicle networks.

For engineers reviewing the PESD2CANFD27V-QBZ datasheet, PESD2CANFD27V-QBZ pinout, PESD2CANFD27V-QBZ application, or PESD2CANFD27V-QBZ equivalent, key selection criteria include low clamping voltage for signal integrity, side-wettable flank package for automated optical inspection, matched diode capacitance (<0.5% ΔCd/Cd), and common-cathode topology enabling compact two-line protection without shared anodes.

Technical Context

This device implements a dual-channel common-cathode TVS diode architecture with independent cathodes (K1, K2) tied to a shared cathode terminal (CC), enabling simultaneous protection of two differential bus lines while minimizing PCB footprint. Its ultra-low 6 pF capacitance per channel ensures minimal signal distortion on high-speed CAN-FD (up to 5 Mbps) and legacy CAN (1 Mbps) interfaces.

The DFN1110D-3 package features side-wettable flanks for solder joint inspection via AOI, 0.65 mm pitch, and 1.1 mm × 1.0 mm × 0.48 mm body dimensions. Thermal performance supports junction temperatures up to 150 °C, validated per AEC-Q101 stress test conditions including temperature cycling, HTRB, and ESD robustness.

FAQ

What is the maximum allowable junction temperature for continuous operation?

The PESD2CANFD27V-QBZ supports continuous operation up to 150 °C junction temperature, verified per AEC-Q101 thermal stress tests including HTGB and temperature cycling. Derating curves in Figure 7 show peak pulse power drops to 40% of rated value at 125 °C, confirming suitability for under-hood environments.

Can this device protect both CAN-H and CAN-L simultaneously using a single footprint?

Yes. Pin 1 (K1) connects to CAN-H, Pin 2 (K2) to CAN-L, and Pin 3 (CC) to system ground or transceiver VSS. This common-cathode configuration protects both lines with matched capacitance and identical clamping behavior, eliminating skew and simplifying layout versus dual-discrete solutions.

Is the 6 pF capacitance specified per channel or total?

The 6 pF capacitance is specified per channel-measured between Pin 1 and Pin 3 (K1–CC) and independently between Pin 2 and Pin 3 (K2–CC)-with matching tolerance ≤0.5% ΔCd/Cd. This ensures symmetrical signal loading on differential bus pairs.

Does the side-wettable flank design require special stencil or reflow profile adjustments?

No. The DFN1110D-3 package uses standard reflow profiles per J-STD-020. Figure 13 provides recommended solder paste land pattern (0.34 mm × 0.88 mm pads, 0.1 mm stencil thickness), and side-wettable flanks are compatible with standard AOI systems without process modification.
