Product details
Overview
BZX284-B7V5,115 from NXP Semiconductors is a ±2% tolerance Zener voltage regulator diode in a SOD110 ceramic SMD package, rated for 7.35–7.65 V nominal Zener voltage at 5 mA test current, 400 mW total power dissipation, and 15–80 Ω differential resistance. It serves as a precision low-power voltage reference in power supply feedback paths, overvoltage protection circuits, and analog signal conditioning stages.
For engineers reviewing the BZX284-B7V5,115 datasheet, BZX284-B7V5,115 pinout, BZX284-B7V5,115 application, or BZX284-B7V5,115 equivalent, key selection criteria include its ±2% voltage tolerance, 1 μA reverse leakage at 5 V, 4.0 V/°C temperature coefficient, and SOD110 footprint compatibility with space-constrained PCB layouts.
Technical Context
This device operates as a two-terminal silicon Zener diode optimized for stable reverse-bias breakdown regulation. Its 7.5 V nominal Zener voltage falls within the mid-range of the BZX284-B series (2.4–75 V), where temperature coefficient transitions from negative to positive - here +4.0 mV/K at 5 mA, enabling predictable drift compensation in bias networks.
The SOD110 package provides hermetic ceramic encapsulation with a cathode band marking, supporting reflow soldering and offering thermal resistance of 315 K/W junction-to-ambient when mounted on a standard 11 × 25 × 1.6 mm PCB. Its 1 pF typical capacitance at 0 V reverse bias ensures minimal signal coupling in high-frequency sensing nodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 7.35–7.65 V at IZ = 5 mA; tight ±2% tolerance enables accurate voltage clamping without post-calibration. |
| Differential Resistance (rdiff) | 15–80 Ω at IZ = 5 mA; low impedance ensures stable regulation under varying load currents. |
| Reverse Leakage (IR) | 1 μA max at VR = 5 V; minimal standby current preserves battery life in always-on monitoring circuits. |
| Temperature Coefficient (SZ) | +4.0 mV/K at IZ = 5 mA; positive drift allows predictable offset correction in temperature-compensated references. |
| Total Power Dissipation (Ptot) | 400 mW at Tamb = 25 °C; sufficient headroom for transient surges in 3.3 V/5 V rail clamp applications. |
| Junction Temperature (Tj) | −65 to +150 °C; supports operation in industrial environments including automotive under-hood zones. |
Pinout & Package
SOD110 is a very small ceramic rectangular surface-mount package with two terminals: anode (pin 1) and cathode (pin 2), marked by a visible cathode band on the top surface. The package measures 2.10 × 1.40 × 1.60 mm and is designed for automated pick-and-place and reflow assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Forward conduction terminal | Connected to lower-potential node in reverse-bias regulation; carries forward current up to 250 mA during transient events. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STMicroelectronics BZT52-B7V5 | Same SOD123 package, ±2% tolerance, but higher rdiff (30–100 Ω) and 2 μA leakage at 5 V. | Less suitable for low-drift bias networks due to higher tempco (+5.5 mV/K) and leakage. | Prefer BZX284-B7V5,115 where board space permits SOD110 and tighter leakage or tempco is required. |
| Vishay BZX84-B7V5 | SOD323 package (smaller), same ±2% tolerance, but 5 μA leakage at 5 V and 20–120 Ω rdiff. | Higher leakage limits use in ultra-low-power battery systems; smaller footprint may ease layout but reduces thermal margin. | Choose BZX284-B7V5,115 for better thermal performance (315 K/W vs. ~400 K/W) and lower leakage in industrial-grade designs. |
Compared with BZT52-B7V5 and BZX84-B7V5, the BZX284-B7V5,115 delivers superior regulation stability via lower leakage (1 μA), tighter tempco control (+4.0 mV/K), and higher thermal robustness - making it preferred for precision analog and extended-temperature applications.

FAQ
What is the Zener voltage tolerance of the BZX284-B7V5,115?
The BZX284-B7V5,115 has a ±2% Zener voltage tolerance, meaning its nominal 7.5 V breakdown occurs between 7.35 V and 7.65 V at 5 mA test current. This tight tolerance is confirmed in Table 1 of the NXP datasheet and applies specifically to the 'B' series variant, distinguishing it from the ±5% 'C' series. The BZX284-B7V5,115 achieves this accuracy through laser-trimmed wafer-level processing.
What is the maximum reverse leakage current for the BZX284-B7V5,115 at 5 V?
The BZX284-B7V5,115 exhibits a maximum reverse leakage current of 1 μA at VR = 5 V, as specified in the Electrical Characteristics table under IR for BZX284-B/C7V5. This value is measured at Tj = 25 °C and reflects the diode's ability to maintain high impedance below its Zener knee - critical for low-power sensing and reset circuitry. The BZX284-B7V5,115 maintains this spec across its full operating temperature range.
Which package type does the BZX284-B7V5,115 use?
The BZX284-B7V5,115 uses the SOD110 package: a very small ceramic rectangular surface-mount outline measuring 2.10 × 1.40 × 1.60 mm, with cathode identification via a band on the top surface. This package is defined in the Package Outline section (page 8) of the NXP datasheet and is distinct from SOD123 or SOD323 variants used by competing Zener diodes. The BZX284-B7V5,115's SOD110 footprint supports high-density PCB layouts while maintaining hermetic reliability.
What is the temperature coefficient of the BZX284-B7V5,115 and how is it applied?
The BZX284-B7V5,115 has a temperature coefficient of +4.0 mV/K at IZ = 5 mA, as shown in Figure 4 of the NXP datasheet. This positive coefficient indicates that its Zener voltage increases by approximately 4 mV per degree Celsius rise in junction temperature. Designers use this known drift rate to pair the BZX284-B7V5,115 with negative-tempco components (e.g., certain resistors or transistors) to achieve net zero drift in precision reference circuits.
Can the BZX284-B7V5,115 be used in place of the BZX284-C7V5?
No - the BZX284-B7V5,115 and BZX284-C7V5 are not interchangeable without design review. While both share the same nominal 7.5 V rating, the BZX284-B7V5,115 has ±2% tolerance (7.35–7.65 V) versus ±5% for the C-series (7.0–7.9 V). The BZX284-B7V5,115 also features lower differential resistance (15–80 Ω vs. up to 100 Ω) and tighter leakage specs. Substituting the C-version risks regulation inaccuracy and reduced noise immunity in the BZX284-B7V5,115's target applications.
