Product details

Overview

BZB84-B22,215 from Nexperia is a dual common-anode Zener diode in SOT23 package, designed for precision voltage regulation and transient suppression in compact DC power rails. It delivers nominal 22 V Zener voltage (21.6–22.4 V), ±2 % tolerance, 250 Ω differential resistance at 5 mA, and supports 1.25 A non-repetitive peak reverse current under 100 µs surge conditions - used in automotive ECU power supply clamping and industrial sensor biasing.

For engineers reviewing the BZB84-B22,215 datasheet, BZB84-B22,215 pinout, BZB84-B22,215 application, or BZB84-B22,215 equivalent, key selection criteria include dual-Zener common-anode topology, AEC-Q101 qualification, 300 mW total power dissipation, thermal resistance of 417 K/W (junction-to-ambient), and SOT23 footprint compatibility with high-density PCB layouts.

Technical Context

This dual Zener diode integrates two independent 22 V Zener elements sharing a common anode (Pin 3), enabling bidirectional voltage clamping or dual-rail reference generation from a single package. Its design supports symmetric reverse breakdown behavior with matched temperature coefficients (±15.4 to ±20.0 mV/K) and low capacitance (60 pF at 1 MHz).

The device operates across −55 °C to +150 °C ambient range, with junction temperature limited to 150 °C. It complies with IEC 60134 absolute maximum ratings and uses FR4 PCB mounting per standard footprint - critical for automotive-grade reliability in engine control and body electronics modules.

Key Specifications

Parameter	Value and Actual Design Meaning
Zener Voltage (V_Z)	21.6 V to 22.4 V at I_Z = 5 mA - defines stable regulation point for 22 V rail protection
Tolerance	±2 % - ensures tight voltage accuracy without post-production trimming
Differential Resistance (r_dif)	250 Ω max at I_Z = 5 mA - determines regulation stiffness under load variation
Total Power Dissipation (P_tot)	300 mW at T_amb ≤ 25 °C - sets continuous DC power handling limit on standard PCB
Non-repetitive Peak Reverse Current (I_ZSM)	1.25 A at t_p = 100 µs - enables transient overvoltage absorption in CAN/LIN bus interfaces
Thermal Resistance (R_th(j-a))	417 K/W - dictates junction temperature rise under steady-state operation on FR4 board
Reverse Current (I_R)	0.05 µA max at V_R = 17.6 V - ensures minimal leakage in high-impedance bias networks

Pinout & Package

SOT23 (TO-236AB) plastic surface-mount package: 3-pin, small outline, lead pitch 0.95 mm, body size 2.9 × 1.3 × 1.0 mm - optimized for automated placement and reflow soldering in space-constrained designs.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
BZB84-C22,215	±5 % Zener tolerance (vs. ±2 %); identical 22 V nominal, same SOT23 package and pinout	Lower cost for non-critical biasing where 22 V ±1.1 V is acceptable	Select when tighter voltage accuracy is unnecessary and BOM cost reduction is prioritized
MMBZ5248BS-7-F	Single Zener (22 V, ±5 %), SOT363 package, 200 mW P_tot, no common-anode dual configuration	Requires two devices for dual-clamp function; higher board area and assembly cost	Choose only if existing design uses SOT363 footprint and dual functionality is implemented discretely

Compared with BZB84-C22,215, the BZB84-B22,215 offers tighter regulation for precision references; versus MMBZ5248BS-7-F, it provides integrated dual-clamp capability in half the footprint and eliminates inter-device matching variance.

FAQ

What is the maximum continuous forward current rating for BZB84-B22,215?

The absolute maximum forward current is 200 mA per diode, specified under DC conditions with ambient temperature ≤25 °C. This rating assumes proper PCB thermal relief and accounts for self-heating effects - exceeding this value risks irreversible junction damage even if average power remains below 300 mW.

How does the common-anode configuration affect circuit implementation?

The common-anode (Pin 3) forces both Zener cathodes (Pins 1 and 2) to be independently connected to separate nodes needing clamping or referencing. This enables bidirectional voltage limiting relative to ground or allows creation of symmetrical ±22 V references using external resistors - unlike single-Zener parts requiring discrete anode ties.

Is BZB84-B22,215 suitable for use in high-frequency signal paths?

Yes - its 60 pF capacitance at 1 MHz and low differential resistance (250 Ω) make it appropriate for clamping RF-coupled transients on analog sensor lines or digital I/O, provided layout minimizes parasitic inductance. However, it is not intended as a high-speed switching element due to Zener recovery time limitations.

What is the thermal resistance from junction to solder point (R_th(j-sp)) and why does it matter?

R_th(j-sp) is 100 K/W, measured between die junction and solder joints at Pins 1 and 2. This parameter directly impacts transient thermal performance: during short surges, heat flows preferentially into copper traces via solder points rather than ambient air, allowing higher peak power handling before junction overheating occurs.
