It delivers stable reference voltage in power supply feedback loops, overvoltage protection circuits, and precision biasing networks for analog front-ends.
For engineers reviewing the BZV49-C5V6115 datasheet, BZV49-C5V6115 pinout, BZV49-C5V6115 application, or BZV49-C5V6115 equivalent, key selection criteria include Zener voltage accuracy, thermal resistance (125 K/W), non-repetitive peak reverse power (40 W), and SOT89 thermal pad compatibility with PCB copper area for heat dissipation.
Technical Context
The BZV49-C5V6115 operates as a two-terminal shunt regulator, conducting in reverse breakdown to clamp voltage across its terminals. Its 5.6 V nominal Zener voltage is specified at IZtest = 5 mA, with differential resistance of ≤40 Ω ensuring low dynamic impedance under load variation.
Designed for surface-mount use on ceramic substrates (2.5 cm², 0.7 mm thick), it supports junction temperatures up to 150 °C and withstands non-repetitive 100 μs surges up to 40 W, enabling robust transient suppression in industrial DC rails.

FAQ
What is the nominal Zener voltage and tolerance of the BZV49-C5V6115?
The BZV49-C5V6115 has a nominal Zener voltage of 5.6 V with a tolerance of ±5%, specified at a test current of 5 mA. This means its actual breakdown voltage falls between 5.2 V and 6.0 V under standard conditions, making it suitable for applications requiring moderate precision without active trimming. The BZV49-C5V6115 achieves this tolerance through E24-series binning and process-controlled doping profiles.
How does the SOT89 package of the BZV49-C5V6115 improve thermal performance compared to SOT23 alternatives?
The SOT89 package of the BZV49-C5V6115 features an exposed thermal pad that reduces junction-to-ambient thermal resistance to 125 K/W when mounted on a 2.5 cm² ceramic substrate-nearly half that of typical SOT23 devices (~300 K/W). This allows the BZV49-C5V6115 to safely dissipate its full 1 W rated power, whereas SOT23 equivalents like BZX84-C5V6 are limited to 350 mW. The BZV49-C5V6115 thus enables higher-power regulation in industrial environments where thermal headroom is critical.
What is the differential resistance of the BZV49-C5V6115 and why does it matter in regulation circuits?
The BZV49-C5V6115 has a typical differential resistance (rdif) of 15 Ω and a maximum of 40 Ω at 5 mA test current. This low dynamic impedance ensures minimal output voltage variation when load current changes-e.g., a ±10 mA shift causes only ±150 mV deviation. In feedback loops or reference networks, this directly translates to tighter regulation accuracy. The BZV49-C5V6115's rdif is significantly lower than many SOT23 Zeners, enhancing stability in precision analog circuits.
Can the BZV49-C5V6115 be used for transient voltage suppression, and what is its surge capability?
Yes, the BZV49-C5V6115 is rated for non-repetitive peak reverse power dissipation of 40 W at 100 μs pulse width, making it suitable for clamping short-duration transients such as ESD or inductive kickback. Its surge current capability reaches 6.0 A under those conditions. Unlike TVS diodes optimized solely for surges, the BZV49-C5V6115 combines steady-state regulation with transient resilience-ideal for dual-role applications like 24 V industrial input protection where both functions coexist. The BZV49-C5V6115's specification is validated per IEC 61000-4-5 surge testing guidelines.
What is the temperature coefficient of the BZV49-C5V6115 and how does it affect long-term stability?
The BZV49-C5V6115 exhibits a positive temperature coefficient of +1.2 mV/K (typical) at 5 mA, meaning its Zener voltage increases by approximately 1.2 mV per degree Celsius rise in junction temperature. This behavior is well-characterized and predictable, allowing designers to compensate for drift in high-accuracy references-e.g., by pairing with negative-TC components. Unlike lower-voltage Zeners with negative coefficients, the BZV49-C5V6115's positive TC makes it especially useful in temperature-compensated voltage references where monotonic drift simplifies calibration. The BZV49-C5V6115's TC is measured across 25–150 °C and documented in Figure 5 of its datasheet.
