Product details

Overview

BZV90-C9V1,115 from Nexperia is a medium-power Zener voltage regulator diode in SOT223 package, designed for precision DC voltage reference and regulation in power supply feedback paths. It delivers a nominal 9.1 V Zener voltage at 5 mA test current, with ±5% tolerance, 6 Ω typical differential resistance, and −3.8 to +5.5 mV/K temperature coefficient. Used in industrial power adapters and embedded microcontroller voltage monitoring circuits.

For engineers reviewing the BZV90-C9V1,115 datasheet, BZV90-C9V1,115 pinout, BZV90-C9V1,115 application, or BZV90-C9V1,115 equivalent, key selection criteria include Zener voltage stability under varying load/temperature, thermal resistance (83.3 K/W), peak surge capability (6.0 A non-repetitive), and SOT223 thermal pad compatibility with PCB copper area design.

Technical Context

This Zener diode operates in reverse breakdown mode with tightly controlled V_Z = 8.5–9.6 V at I_Ztest = 5 mA. Its low differential resistance (6–15 Ω) ensures minimal output voltage variation across regulated current changes, critical for stable reference generation.

The device features a negative-to-positive temperature coefficient range (−3.8 to +5.5 mV/K), enabling predictable drift compensation in multi-diode reference networks. Thermal performance is defined for FR4 double-sided PCBs with 2 cm² copper area, supporting continuous 1.5 W dissipation at T_amb = 25 °C.

Equivalent & Alternatives

The following parts are listed as comparable options for similar Zener voltage reference applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BZX84-C9V1	Same V_Z (8.5–9.6 V), but SOT23 package, 350 mW P_tot, higher r_dif (20 Ω typ.)	Limited to low-power signal-level references; unsuitable for >50 mA regulation loads	Select when board space is critical and power <0.35 W; avoid in power supply feedback
MMSZ5240B	V_Z = 10 V (9.5–10.5 V), SOD-123 package, 500 mW P_tot, 17 Ω r_dif	Higher nominal voltage and lower power rating require circuit redesign for 9.1 V use cases	Choose only if 10 V reference is acceptable and thermal budget permits 500 mW limit

Compared with BZX84-C9V1 and MMSZ5240B, the BZV90-C9V1,115 provides 4.3× higher power handling and 2.8× lower differential resistance-making it uniquely suitable for shunt regulation in mid-power industrial supplies where thermal margin and voltage stability are co-critical.

FAQ

What is the maximum continuous Zener current for BZV90-C9V1,115 at 25 °C ambient?

The device supports up to 165 mA continuous Zener current at 25 °C ambient, calculated from P_tot = 1500 mW and V_Z ≈ 9.1 V. Derating begins above 25 °C per the 83.3 K/W thermal resistance; at 70 °C ambient, max current drops to ~110 mA to maintain T_j ≤ 150 °C.

Can BZV90-C9V1,115 be used in parallel for higher current handling?

No-Zener diodes exhibit negative temperature coefficients and mismatched V_Z tolerances, causing current hogging and thermal runaway when paralleled. For higher current, use a single higher-power device or implement active regulation with a pass transistor driven by this Zener reference.

Is the SOT223 package lead-free and RoHS compliant?

Yes-Nexperia confirms the BZV90-C9V1,115 SOT223 package meets RoHS Directive 2011/65/EU and is lead-free, with matte tin (Sn) termination and halogen-free molding compound. The device is qualified per JEDEC J-STD-020 moisture sensitivity level 3.

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

With S_Z = −3.8 to +5.5 mV/K, V_Z drift over 165 K span is −0.63 V to +0.91 V-i.e., total possible shift of up to ±10% from nominal 9.1 V. For high-accuracy systems, this requires either calibration, temperature compensation, or selection of tighter-coefficient alternatives like BZT52-B9V1 (±2 mV/K).
