Product details

Overview

BZB84-C7V5-QR from Nexperia is a dual Zener diode in SOT23 package with nominal 7.5 V regulation voltage (±5 % tolerance), common-anode configuration, 300 mW total power dissipation, and AEC-Q101 qualification for automotive use.

For engineers reviewing the BZB84-C7V5-QR datasheet, BZB84-C7V5-QR pinout, BZB84-C7V5-QR application, or BZB84-C7V5-QR equivalent, this part supports dual-rail voltage reference, overvoltage clamping, and precision biasing in space-constrained automotive ECUs and industrial sensor interfaces where thermal robustness and production-grade reliability are required.

Technical Context

This dual Zener diode integrates two independent 7.5 V Zener elements sharing a common anode terminal, enabling compact dual-voltage referencing or bidirectional transient suppression in single-package layout. Its differential resistance of ≤80 Ω at I_Z = 5 mA ensures stable regulation under load variation.

The device operates across –55 °C to +150 °C ambient, with junction-to-ambient thermal resistance of 417 K/W on FR4 PCB, and exhibits a positive temperature coefficient of +2.5 to +5.3 mV/K - critical for temperature-compensated reference designs requiring predictable drift behavior.

Key Specifications

Parameter	Value and Actual Design Meaning
Zener Voltage V_Z	7.00 V to 7.90 V at I_Z = 5 mA - defines usable regulation window for 7.5 V nominal rail
Tolerance	±5 % (C-series) - enables cost-optimized selection where tight voltage accuracy is not mission-critical
Total Power Dissipation	300 mW at T_amb ≤ 25 °C - sets maximum continuous DC power handling per device
Non-repetitive Peak Power	40 W at t_p = 100 µs - supports surge suppression for ESD or load-dump transients
Differential Resistance	≤80 Ω at I_Z = 5 mA - determines output impedance and regulation error under current step loads
Reverse Current I_R	≤1 µA at V_R = 5.0 V - ensures low leakage in standby-biased reference circuits
Thermal Resistance R_th(j-a)	417 K/W - quantifies self-heating impact on Zener voltage stability in unforced-air environments

Pinout & Package

SOT23 plastic surface-mount package (2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm pin pitch) with gull-wing leads and standardized footprint per Fig. 12–13 of Nexperia's datasheet.

Use Scenario: Clamping and biasing 4–20 mA transmitter outputs in hazardous-area pressure transmitters operating at 75 °C ambient.

IC Role / Device Role / Timing Role: Zener pair suppresses induced transients on loop-powered analog lines while supplying local bias for current-sense amplifiers.

Use Value: 40 W surge rating handles field-induced spikes up to 100 µs without degradation; ±5 % tolerance aligns with industrial 4–20 mA accuracy requirements.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
ON Semiconductor MMBZ5231BS	Single Zener (5.1 V), SOT23, ±5 %, 225 mW - no dual configuration or common-anode topology	Requires two devices and extra routing for dual-rail use; lacks integrated thermal tracking	Select only when single-rail reference suffices and board area is not constrained
Vishay BZX84-C7V5	Single Zener (7.5 V), SOT23, ±5 %, 300 mW - no second cathode or common-anode capability	Cannot support simultaneous dual-reference or bidirectional clamping without external components	Choose if only one regulated rail is needed and cost-per-function is prioritized over integration

Compared with MMBZ5231BS and BZX84-C7V5, BZB84-C7V5-QR uniquely delivers dual 7.5 V Zener regulation in one SOT23 footprint with matched thermal behavior and AEC-Q101 validation - making it the only option for space-limited automotive dual-reference designs requiring production-grade reliability.

FAQ

What is the maximum continuous reverse current for BZB84-C7V5-QR at 7.5 V?

The device is rated for continuous Zener current up to 40 mA at 7.5 V, derived from its 300 mW total power dissipation limit (P = V × I → I = 300 mW / 7.5 V = 40 mA). Operation above this level requires thermal derating per the datasheet's ambient temperature curves.

Can BZB84-C7V5-QR be used for bidirectional ESD protection?

No - its common-anode dual-cathode structure supports only unidirectional clamping from either cathode to the shared anode. For true bidirectional protection, a dedicated TVS array or back-to-back Zener pair with separate anodes is required.

How does the temperature coefficient affect regulation accuracy over –40 °C to +125 °C?

At 7.5 V, the specified temperature coefficient is +2.5 to +5.3 mV/K. Over a 165 K range, this introduces a worst-case drift of +0.87 V, meaning the actual Zener voltage may shift from ~7.0 V at –40 °C to ~7.9 V at +125 °C - a deviation within its ±5 % initial tolerance band.

Is the SOT23 footprint compatible with standard reflow profiles for lead-free assembly?

Yes - Nexperia specifies compatibility with IPC/JEDEC J-STD-020D reflow profiles. The recommended solder land pattern (Fig. 12) uses 0.6 mm × 0.6 mm pads with 0.7 mm spacing, supporting peak temperatures up to 260 °C for 10 seconds without delamination or parametric shift.
