Product details
Overview
BZV49-C7V5 from Nexperia is a medium-power Zener voltage regulator diode in SOT89 package, designed for precision DC voltage reference and regulation at nominal 7.5 V with ±5% tolerance, 5 mA test current, 6–15 Ω differential resistance, and −40 °C to +150 °C junction temperature range; used in power supply feedback loops and analog sensor biasing.
For engineers reviewing the BZV49-C7V5 datasheet, BZV49-C7V5 pinout, BZV49-C7V5 application, or BZV49-C7V5 equivalent, key selection criteria include Zener voltage accuracy at 5 mA, thermal resistance (15 K/W junction-to-tie-point), non-repetitive peak reverse power (40 W), and SOT89 thermal pad compatibility with PCB copper area.
Technical Context
The BZV49-C7V5 operates as a two-terminal shunt regulator, maintaining stable output voltage by conducting reverse current above its specified Zener breakdown threshold. Its 7.0–7.9 V working voltage range (min/max at 25 °C) and +2.5 to +5.3 mV/K positive temperature coefficient enable predictable drift compensation in mid-voltage rails.
Designed for surface-mount implementation on ceramic substrates (2.5 cm², 0.7 mm thick), it delivers 1 W total power dissipation with 125 K/W junction-to-ambient thermal resistance-requiring careful PCB copper pour design to sustain continuous operation near rated limits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 7.0–7.9 V at IZtest = 5 mA; defines regulated output voltage window under standard test conditions |
| Differential Resistance rdif | 6–15 Ω; determines output impedance and load regulation sensitivity near operating point |
| Temp. Coefficient SZ | +2.5 to +5.3 mV/K; quantifies voltage drift per degree Celsius rise in junction temperature |
| Power Dissipation Ptot | 1 W at Tamb = 25 °C; maximum continuous power before thermal derating applies |
| Non-repetitive Peak Power | 40 W for tp = 100 μs; supports transient overvoltage clamping without failure |
| Junction Temperature Tj | −65 to +150 °C; sets operational envelope for reliability in industrial environments |
| Reverse Current IR | ≤1 μA at VR = 5.0 V; ensures low leakage in standby or high-impedance bias networks |
Pinout & Package
SOT89 plastic surface-mounted package with exposed collector pad (Pin 3) for enhanced thermal conduction; 3-lead outline compliant with JEDEC TO-243/SC-62 standards; requires minimum 2.5 cm² ceramic substrate for full 1 W rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode | Forward current entry point; connected to lower-potential node in shunt regulation configuration |
| 2 | Cathode | Zener breakdown terminal; connected to regulated voltage rail and current-limiting resistor |
| 3 | Anode (tie-point) | Thermal pad tied internally to anode; must be soldered to PCB copper for thermal management |
Key Features
| Feature | Design Value |
|---|---|
| E24 ±5% voltage tolerance | Enables precise binning across 37 types (2.4–75 V); reduces need for post-production calibration |
| 15 K/W junction-to-tie-point Rth | Allows effective heat transfer from die to PCB copper via Pin 3, supporting sustained 1 W operation |
| 40 W non-repetitive peak power | Clamps short-duration transients (e.g., ESD, inductive kickback) without degradation |
| Low 150 pF capacitance at 0 V | Minimizes signal distortion in high-frequency bias or reference applications up to ~1 MHz |

FAQ
What is the maximum continuous reverse current the BZV49-C7V5 can handle at 25 °C?
The BZV49-C7V5 has no specified maximum continuous reverse current rating; instead, its safe operating limit is defined by total power dissipation (1 W). At nominal 7.5 V Zener voltage, this corresponds to approximately 133 mA average reverse current (P = V × I), assuming adequate PCB thermal design per the 2.5 cm² ceramic substrate requirement.
Can the BZV49-C7V5 replace a 1N4733A in a 5 V circuit?
No-the BZV49-C7V5 is a 7.5 V Zener diode and cannot substitute for the 5.1 V 1N4733A. Its minimum Zener voltage is 7.0 V, exceeding the 1N4733A's 4.8–5.4 V range. Using it in a 5 V circuit would prevent proper regulation and risk excessive power dissipation in the current-limiting resistor.
How does the SOT89 package's Pin 3 function electrically and thermally?
Pin 3 is internally connected to the anode and serves as the thermal tie-point-not an independent electrical terminal. It must be soldered to a PCB copper pour to conduct heat away from the junction. Electrically, it is shorted to Pin 1; thermally, it reduces Rth(j-tp) to 15 K/W, enabling higher continuous power handling than standard SOD-123 packages.
Is the BZV49-C7V5 suitable for use in automotive applications?
While the BZV49-C7V5 meets AEC-Q200 stress test recommendations for passive components, it is not officially AEC-Q101 qualified as a discrete semiconductor. For automotive-grade designs, Nexperia offers the BZX84-C7V5 (SOT23) and BZX384-C7V5 (SOD323) as qualified alternatives; this part is recommended for industrial and commercial applications only.
