Nexperia USA Inc. BZB84-B16VL

Overview

BZB84-B16VL from Nexperia is a dual common-anode Zener diode in SOT23 package, designed for precision voltage regulation and overvoltage protection in compact PCB layouts. It delivers nominal 16 V Zener voltage (±2 % tolerance), 200 mA forward current rating, 300 mW total power dissipation, and 40 W non-repetitive peak reverse power capability - used in automotive body control modules for rail stabilization.

For engineers reviewing the BZB84-B16VL datasheet, BZB84-B16VL pinout, BZB84-B16VL application, or BZB84-B16VL equivalent, key selection criteria include dual-Zener common-anode topology, AEC-Q101 qualification, 15.7–16.3 V working voltage range at I_Z = 5 mA, and thermal resistance of 417 K/W (junction-to-ambient).

Technical Context

This dual Zener diode integrates two independent Zener junctions sharing a common anode terminal (Pin 3), enabling bidirectional clamping or dual-rail regulation from a single footprint. Its ±2 % voltage tolerance and low differential resistance (200 Ω max at I_Z = 5 mA) support stable reference generation in feedback loops.

Rated for automotive-grade reliability (AEC-Q101), it operates across −55 °C to +150 °C ambient, with junction temperature limited to 150 °C. The SOT23 package supports reflow and wave soldering per JEDEC J-STD-020 and J-STD-006 standards.

Key Specifications

Pinout & Package

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual-Zener regulation applications.

Compared with BZB84-B16VL, DMN3020LSD-13 offers active switching but lacks symmetric dual-Zener clamping, while BZX84-C16 doubles assembly cost and footprint to replicate basic dual-rail protection - making BZB84-B16VL optimal for space-constrained, AEC-Q101-compliant dual-threshold designs.

FAQ

What is the maximum continuous power dissipation for BZB84-B16VL at 70 °C ambient?

At 70 °C ambient, derating applies per the thermal resistance curve: R_th(j-a) = 417 K/W. With T_j(max) = 150 °C, allowable ΔT = 80 K, so P_tot = 80 K / 417 K/W ≈ 192 mW. This ensures safe operation without exceeding junction temperature limits under sustained load.

Can BZB84-B16VL replace two separate BZX84-C16 diodes in a common-cathode configuration?

No - BZB84-B16VL has a common-anode structure (Pin 3 = anode), whereas common-cathode requires shared cathode. Using it in place of two BZX84-C16 devices would invert polarity and disrupt circuit function unless the schematic is redesigned to accommodate common-anode topology.

Is the 40 W non-repetitive peak power rating tested per diode or for the entire package?

The 40 W rating applies per diode, as confirmed in Table 1 and Section 5: "Per diode PZSM non-repetitive peak reverse power dissipation". Both diodes can independently handle 40 W surges if thermally isolated, but simultaneous full-power operation is limited by total package dissipation (300 mW DC).

Does the marking code 'PT*' on BZB84-B16VL indicate manufacturing location or lot traceability?

'PT*' is the device-specific marking code per Table 4; the asterisk denotes manufacturing origin: '-' = Hong Kong, 'p' = Hong Kong, 't' = Malaysia, 'W' = China. It does not encode lot number - full traceability requires scanning the reel label barcode per Nexperia's packaging documentation.
