Product details
Overview
BZT52H-C15,115 from Nexperia is a ±5 % tolerance Zener diode in SOD123F package, rated for 15 V nominal breakdown voltage at IZ = 5 mA, with 830 mW total power dissipation and 110 Ω maximum differential resistance - used for precision voltage reference and overvoltage clamping in low-power analog supply rails.
For engineers reviewing the BZT52H-C15,115 datasheet, BZT52H-C15,115 pinout, BZT52H-C15,115 application, or BZT52H-C15,115 equivalent, this part supports stable 15 V regulation under 5 mA test current, operates across –65 °C to +150 °C ambient, and delivers <15 μA reverse leakage at 12 V, making it suitable for compact DC-DC feedback networks and ESD-protected sensor biasing.
Technical Context
This Zener diode operates in reverse-biased avalanche mode with a specified 15 V nominal Zener voltage (VZ) at 5 mA test current, exhibiting a temperature coefficient of +9.2 mV/K and 75 pF junction capacitance at 0 V. Its thermal resistance from junction to ambient is 330 K/W on standard FR4 PCB.
The device features a cathode-anode two-terminal configuration, marked with a bar indicating the cathode, and is optimized for surface-mount reflow soldering per IPC-J-STD-020. It complies with IEC 60134 absolute maximum ratings, including 250 mA forward current and 150 °C junction temperature limit.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VZ (Nominal) | 15 V at IZ = 5 mA - defines stable regulation point for feedback or reference circuits |
| Tolerance | ±5 % - allows predictable voltage margin in non-critical regulation paths |
| Ptot | 830 mW at Tamb ≤ 25 °C - sets maximum continuous power handling on standard FR4 PCB |
| rdif | 110 Ω max - determines output impedance and load regulation sensitivity |
| IR @ VR = 12 V | <15 μA - ensures minimal quiescent current draw in standby or low-power modes |
| Package | SOD123F - 3.6 mm × 1.2 mm footprint with 0.7 mm height, compatible with automated SMT assembly |
| Tj max | 150 °C - defines upper thermal operating limit for reliability in enclosed or high-ambient environments |
Pinout & Package
SOD123F is a 2-pin surface-mount plastic package with gull-wing leads; cathode marked by a bar on the body. Mounting pad for cathode requires 1 cm² copper area for full 830 mW rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; polarity-sensitive for reverse-bias operation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5245BS-7-F (Diodes Inc.) | 15 V, ±5 %, SOT-323 package, 350 mW Ptot, 150 Ω rdif | Lower power rating limits use in >350 mW continuous regulation; smaller footprint reduces thermal mass | Select when board space is constrained and thermal load is ≤350 mW; verify layout copper area for derating. |
| BZX84-C15 (Nexperia) | 15 V, ±5 %, SOT-23 package, 300 mW Ptot, 150 Ω rdif, same marking code BN | Lower power and higher impedance reduce regulation stability under varying loads | Choose only for ultra-low-power signal-level clamping where 300 mW suffices and SOT-23 is preferred. |
Compared with MMBZ5245BS-7-F and BZX84-C15, BZT52H-C15,115 offers 2.8× higher power handling and 30 % lower dynamic impedance - critical for maintaining regulation accuracy in 5–10 mA load ranges typical of analog feedback loops.

FAQ
What is the Zener voltage test condition for BZT52H-C15,115?
The nominal 15 V Zener voltage is measured at IZ = 5 mA, Tj = 25 °C, using pulse conditions (tp ≤ 300 μs, duty cycle ≤ 0.02) to avoid self-heating effects. This ensures repeatable characterization for feedback loop design and voltage reference validation.
Can BZT52H-C15,115 be used in automotive applications?
No - BZT52H-C15,115 is not automotive-qualified. The datasheet explicitly states that this part is non-automotive and lacks AEC-Q101 qualification. For automotive use, Nexperia offers the -Q qualified BZT52H-Q series with extended temperature screening and PPAP documentation.
How does the ±5 % tolerance affect regulation accuracy in practice?
At 15 V nominal, ±5 % tolerance means VZ falls between 14.25 V and 15.75 V at 5 mA. In feedback applications, this directly translates to corresponding output voltage variation unless compensated by trimming resistors or digital calibration - acceptable for non-critical biasing but insufficient for precision references.
What is the recommended PCB layout for achieving full 830 mW power rating?
To achieve the full 830 mW rating, the cathode pad must be mounted on an FR4 PCB with single-sided 1 cm² tin-plated copper area. Standard footprint without extended copper limits Ptot to 375 mW; thermal simulation or IR imaging is advised when operating above 500 mW continuously.
