Product details

Overview

BZV90-C7V5,115 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 7.5 V Zener voltage at 5 mA test current, with ±5% tolerance, 6–15 Ω differential resistance, and +2.5 to +4.0 mV/K temperature coefficient. It supports continuous forward current up to 400 mA and handles non-repetitive peak reverse power up to 40 W for surge protection.

For engineers reviewing the BZV90-C7V5,115 datasheet, BZV90-C7V5,115 pinout, BZV90-C7V5,115 application, or BZV90-C7V5,115 equivalent, key selection criteria include Zener voltage stability under varying load/temperature, thermal resistance (83.3 K/W), SOT223 thermal pad capability, and compatibility with 5 mA test-current-based feedback networks in SMPS and LDO circuits.

Technical Context

This Zener diode operates in reverse breakdown mode to maintain stable output voltage across variable load and input conditions. Its low differential resistance (6–15 Ω) ensures minimal voltage deviation under current changes, while its positive temperature coefficient (+2.5 to +4.0 mV/K) enables predictable drift compensation in multi-diode references.

The SOT223 package integrates a large copper collector pad for enhanced thermal dissipation-critical for sustaining 1.5 W total power dissipation at Tamb = 25 °C on FR4 PCB with 2 cm² copper area. Pin configuration (anode-cathode-anode-cathode) supports dual-anode layout flexibility in compact board designs.

Key Specifications

Parameter	Value and Actual Design Meaning
Zener Voltage (V_Z)	7.0–7.9 V at I_Ztest = 5 mA; defines regulated output level in feedback loops
Differential Resistance (r_dif)	6–15 Ω at I_Ztest = 5 mA; determines voltage variation per mA load change
Temperature Coefficient (S_Z)	+2.5 to +4.0 mV/K at I_Ztest = 5 mA; quantifies voltage drift over operating temperature range
Total Power Dissipation (P_tot)	1500 mW at T_amb = 25 °C; sets maximum steady-state thermal load on PCB copper area
Non-repetitive Peak Power (P_ZSM)	40 W for t_p = 100 μs; enables transient overvoltage clamping without failure
Junction Temperature (T_j)	− to +150 °C; defines maximum allowable silicon operating temperature under bias
Reverse Current (I_R)	≤1 μA at V_R = 5.0 V; ensures low leakage in high-impedance reference nodes

Pinout & Package

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-C7V5	Same 7.5 V nominal Zener voltage but in SOT23 package; P_tot = 300 mW; r_dif = 15 Ω typical	Limited to low-power references; unsuitable for >150 mW sustained dissipation or surge clamping	Select when board space is constrained and thermal load ≤150 mW; avoid in SMPS feedback or automotive transients
MMSZ5235B	7.5 V Zener in SOD-123; P_tot = 500 mW; r_dif = 10 Ω; T_j max = 150 °C	Lower power rating and no thermal pad; higher R_{th j-a} (~200 K/W)	Prefer for cost-sensitive consumer applications where 500 mW suffices and thermal margin is adequate

Compared with BZX84-C7V5 and MMSZ5235B, the BZV90-C7V5,115 offers 3× higher power handling and superior thermal performance via SOT223 pad-making it the only choice among the three for 1.5 W regulation or 40 W surge duty in industrial and automotive systems.

FAQ

What is the recommended PCB layout for optimal thermal performance of BZV90-C7V5,115?

Mount the device on FR4 with ≥2 cm² double-sided copper area connected directly to pins 2, 4 (cathodes) and pin 3 (thermal pad/anode). Use thermal vias under pin 3 to inner ground planes. Avoid soldermask over copper areas contacting pins 2, 3, and 4 to maximize heat transfer and sustain 1.5 W continuous dissipation.

Can BZV90-C7V5,115 be used in series or parallel configurations?

Series use is valid for higher-voltage references (e.g., two 7.5 V devices for 15 V), provided matching V_Z and temperature coefficients are verified. Parallel use is not recommended due to mismatched r_dif causing current imbalance and thermal runaway-individual devices must be isolated by series resistors if paralleled.

What is the maximum allowable reverse voltage before breakdown?

The rated Zener voltage is 7.5 V nominal with guaranteed 7.0–7.9 V range at 5 mA. Below 5.0 V reverse bias, leakage remains ≤1 μA. Breakdown onset begins near 6.5 V, but stable regulation requires operation ≥7.0 V and within the specified I_Z range (1–20 mA) per datasheet curves.

How does temperature affect regulation accuracy in practical circuits?

At +2.5 to +4.0 mV/K, V_Z increases ~0.3–0.5 V from −40 °C to +125 °C ambient. For ±0.5% regulation over temperature, pair with a negative-coefficient reference or use in closed-loop feedback where op-amp compensation mitigates drift-direct use in open-loop references requires derating.
