Diodes Incorporated ZVN2106ASTOB

Overview

ZVN2106ASTOB from Diodes Incorporated is an N-channel enhancement-mode vertical DMOS FET rated for 60 V V_DS, 2 Ω R_DS(on) at V_GS = 10 V and I_D = 1 A, with 450 mA continuous drain current at 25°C ambient. It serves as a low-voltage logic-level power switch in compact DC-DC converters, LED drivers, and battery protection circuits.

For engineers reviewing the ZVN2106ASTOB datasheet, ZVN2106ASTOB pinout, ZVN2106ASTOB application, or ZVN2106ASTOB equivalent, key selection criteria include verified R_DS(on) ≤ 2 Ω at 10 V gate drive, TO-92-compatible leaded package thermal performance, and confirmed 60 V breakdown margin under pulsed 8 A loads.

Technical Context

This discrete MOSFET operates in enhancement mode with a gate-threshold voltage (V_GS(th)) ranging from 0.8 V to 2.4 V at I_D = 1 mA, enabling direct interface with 3.3 V and 5 V logic controllers. Its vertical DMOS structure delivers low on-resistance while maintaining robust avalanche ruggedness.

Electrical behavior is characterized by 300 mS forward transconductance (g_fs) at V_DS = 18 V and I_D = 1 A, and capacitance values of C_iss = 75 pF, C_oss = 45 pF, and C_rss = 20 pF at V_DS = 18 V, supporting efficient switching in sub-MHz power control applications.

FAQ

Is ZVN2106ASTOB suitable for 3.3 V logic-level gate drive?

Yes. With a guaranteed V_GS(th) as low as 0.8 V and typical R_DS(on) of 2 Ω at V_GS = 4.5 V (per characterization curves), it reliably turns on using 3.3 V GPIO outputs. Full enhancement occurs at ≥4.5 V, delivering near-minimum on-resistance.

What is the maximum safe operating temperature for continuous use?

The device supports junction temperatures from −55°C to +150°C. For continuous 450 mA operation in TO-92, ambient must remain ≤70°C with adequate PCB copper area (≥1 cm² per lead) to maintain T_j < 125°C per derating curves in the datasheet.

Can ZVN2106ASTOB replace a 2N7000 in existing designs?

Yes, with verification. Both are TO-92 N-channel MOSFETs, but ZVN2106ASTOB offers lower R_DS(on) (2 Ω vs. 5 Ω), higher V_DS (60 V vs. 60 V), and tighter V_GS(th) (0.8–2.4 V vs. 0.8–3.0 V), improving efficiency and drive margin in most 2N7000-replacement cases.

Does this part have built-in ESD protection?

No. ZVN2106ASTOB has no integrated ESD protection diodes. Gate-source leakage is specified at 20 nA at ±20 V, confirming absence of clamping structures. External 10 kΩ gate resistor and TVS diode are recommended for handling >2 kV HBM events in assembly and field use.
