Product details
Overview
BZV49-C13,115 from Nexperia is a medium-power Zener voltage regulator diode in SOT89 package, designed for precision DC voltage reference and stabilization in power supply rails. It delivers a nominal Zener voltage of 13 V at 5 mA test current, with ±5% tolerance, 10 Ω typical differential resistance, and −5.0 to +11.0 mV/K temperature coefficient. Used in industrial power monitoring circuits requiring stable 13 V regulation under variable thermal conditions.
For engineers reviewing the BZV49-C13,115 datasheet, BZV49-C13,115 pinout, BZV49-C13,115 application, or BZV49-C13,115 equivalent, this page provides verified electrical parameters, thermal resistance (15 K/W junction-to-tie-point), reverse current limits (≤0.1 μA at 10.4 V), non-repetitive surge capability (8.0 A peak), and SOT89 mechanical layout for PCB layout validation and thermal design.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain a stable reference voltage across its cathode-anode terminals. Its 13 V nominal working voltage is specified at IZtest = 5 mA, with differential resistance of ≤30 Ω (max) and temperature coefficient ranging from −5.0 to +11.0 mV/K depending on operating current.
The device uses silicon planar technology in a plastic SOT89 surface-mount package with an exposed collector pad for enhanced thermal conduction. It supports continuous power dissipation up to 1 W at 25 °C ambient and withstands non-repetitive peak reverse power surges of 40 W for 100 μs pulses.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 12.4 V to 14.1 V at 5 mA - defines regulated output range for 13 V nominal rail |
| Differential Resistance rdif | ≤30 Ω (max) - determines load regulation error under varying current |
| Temperature Coefficient SZ | −5.0 to +11.0 mV/K - quantifies voltage drift per degree Celsius change |
| Reverse Current IR | ≤0.1 μA at 10.4 V - ensures low leakage in standby or high-impedance bias networks |
| Non-repetitive Peak Reverse Current IZSM | 8.0 A at 100 μs - enables transient overvoltage clamping without failure |
| Total Power Dissipation Ptot | 1 W at Tamb = 25 °C - sets maximum steady-state thermal load on PCB copper area |
| Junction-to-Tie-Point Thermal Resistance Rth(j-tp) | 15 K/W - critical for calculating die temperature rise when mounted on ceramic substrate |
Pinout & Package
Package: SOT89 (SC-62), plastic surface-mounted package with exposed collector pad for thermal conduction; 3 leads, 4.6 mm × 2.6 mm footprint, 1.6 mm height.
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C13 | Same 13 V nominal Zener voltage but in smaller SOT23 package; 350 mW power rating vs. 1 W | Lower thermal mass and power handling - suitable only for low-current (<25 mA) references | Select when board space is constrained and power dissipation remains below 350 mW |
| MMSZ4686 | 13 V Zener in SOD-123; 500 mW rating; higher max reverse current (1.0 μA at 10.4 V) | Higher leakage and lower surge capability (5.0 A vs. 8.0 A) - less robust in noisy environments | Select when cost sensitivity outweighs thermal and surge performance requirements |
Compared with BZX84-C13 and MMSZ4686, the BZV49-C13,115 offers superior thermal management via SOT89 pad and 2.3× higher surge current rating - critical for industrial and automotive applications where reliability under transient stress is mandatory.

FAQ
What is the maximum continuous reverse power dissipation for BZV49-C13,115?
The BZV49-C13,115 has a maximum total power dissipation of 1 W at 25 °C ambient temperature when mounted on a 2.5 cm² ceramic substrate. Derating is required above 25 °C at 8 mW/°C based on its 125 K/W junction-to-ambient thermal resistance.
Does BZV49-C13,115 have a specified forward voltage?
Yes - the forward voltage is specified as ≤1.0 V at 50 mA forward current. This value is relevant for fault-condition analysis and reverse-polarity protection design, not for normal Zener operation which occurs in reverse bias.
Can BZV49-C13,115 be used in place of a 12 V Zener diode?
No - its nominal Zener voltage is 13 V with a guaranteed range of 12.4 V to 14.1 V. Substituting it for a 12 V part would shift regulation by ≥0.4 V, potentially violating downstream IC voltage tolerances or comparator thresholds.
What is the significance of the "115" suffix in BZV49-C13,115?
The "115" is Nexperia's internal ordering code denoting tape-and-reel packaging in 1000-unit reels, compliant with EIA-481-D standards. It does not affect electrical characteristics but identifies the logistics format for automated assembly.
