Product details
Overview
BZT52H-C4V7,115 from Nexperia is a ±5 % tolerance Zener diode in SOD123F package, rated for 4.7 V nominal breakdown voltage at IZ = 5 mA, with 830 mW total power dissipation and 78 Ω maximum differential resistance - used for precision voltage reference and overvoltage clamping in low-power analog supply rails.
For engineers reviewing the BZT52H-C4V7,115 datasheet, BZT52H-C4V7,115 pinout, BZT52H-C4V7,115 application, or BZT52H-C4V7,115 equivalent, this device serves as a stable, surface-mount voltage regulator in space-constrained DC-DC feedback networks, sensor biasing circuits, and microcontroller reset supervision where tight voltage tolerance and thermal stability are required.
Technical Context
This Zener diode operates in reverse-biased breakdown mode to maintain a stable 4.7 V reference across its terminals under regulated current conditions (IZ = 5 mA), with temperature coefficient of −3.5 mV/K to +0.2 mV/K and reverse leakage <3 μA at VR = 3.76 V. Its SOD123F package enables high-density PCB layout while supporting reflow soldering only.
The device exhibits 300 pF junction capacitance at VR = 0 V and f = 1 MHz, and supports non-repetitive peak reverse current up to 6.0 A (tp = 100 μs), making it suitable for transient suppression in low-energy signal paths without requiring external series limiting resistors in many cases.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage (VZ) | 4.40 V to 5.00 V at IZ = 5 mA - defines usable regulation window for 4.7 V nominal rail stabilization |
| Differential Resistance (rdif) | ≤ 78 Ω - ensures minimal output voltage shift under load current variations up to ±1 mA |
| Reverse Leakage (IR) | ≤ 3 μA at VR = 3.76 V - guarantees low quiescent current draw in always-on bias networks |
| Total Power Dissipation (Ptot) | 830 mW at Tamb ≤ 25 °C on FR4 PCB with 1 cm² cathode pad - sets maximum continuous DC power handling in standard layouts |
| Forward Voltage (VF) | ≤ 0.9 V at IF = 10 mA - enables use as low-drop rectifier or ESD clamp in forward conduction mode |
| Junction Temperature (Tj) | −65 °C to +150 °C - supports operation in industrial ambient environments without derating below −40 °C |
| Thermal Resistance (Rth(j-sp)) | 70 K/W - quantifies thermal path efficiency from junction to cathode solder point for thermal design margining |
Pinout & Package
SOD123F is a 2-lead surface-mount plastic package with 1.2 mm height, 3.5 mm length, and 1.6 mm width; cathode marked by a bar on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; polarity marker determines correct orientation during placement |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZT52C4V7,115 | Same electrical specs but ±5 % tolerance in legacy BZT52C series; identical SOD123F package and marking (BA) | No functional difference; BZT52H replaces BZT52C with improved thermal resistance and tighter production controls | Select BZT52H-C4V7,115 for new designs requiring latest revision compliance and enhanced thermal performance |
| MMBZ5225BS-7-F | 4.7 V ±5 %, SOT-23 package, 350 mW Ptot, 100 Ω rdif - lower power and higher impedance than BZT52H-C4V7,115 | Suitable only for ultra-low-current references (<5 mA); not recommended for >10 mA load regulation | Choose only if board space is constrained to SOT-23 footprint and power demand is <150 mW |
Compared with BZT52C4V7,115, the BZT52H-C4V7,115 offers improved thermal resistance (70 K/W vs. ~90 K/W) and tighter process control, while MMBZ5225BS-7-F trades power capability for smaller size - making the H-series optimal for robust 4.7 V regulation at moderate currents.

FAQ
What is the maximum continuous reverse current the BZT52H-C4V7,115 can sustain without degradation?
The device is rated for 250 mA maximum forward current, but in Zener operation, sustained reverse current is limited by power dissipation. At 4.7 V, continuous IZ must stay ≤175 mA to remain within 830 mW Ptot at 25 °C ambient - derating applies above 25 °C per Rth(j-a) = 330 K/W.
Does the BZT52H-C4V7,115 support wave soldering or only reflow?
Reflow soldering is the only recommended method per Nexperia's documentation. Wave soldering is not supported due to thermal stress risks on the SOD123F plastic body and internal wire bonds - use lead-free reflow profile with peak temperature ≤260 °C and time above liquidus ≤60 seconds.
How does the temperature coefficient affect regulation accuracy over −40 °C to +85 °C?
For BZT52H-C4V7,115, SZ ranges from −3.5 mV/K to +0.2 mV/K. Over −40 °C to +85 °C (ΔT = 125 K), worst-case VZ drift is ±438 mV - but typical behavior shows <±100 mV shift due to curvature compensation, verified in Fig. 6 of the datasheet.
Can this Zener be used in parallel for higher power handling?
No - Zener diodes exhibit manufacturing spread in VZ, causing current hogging when paralleled. Even matched units require ballast resistors (≥10 Ω each) to ensure balanced sharing, which defeats the purpose of increased power density; use a single higher-rated device instead.
