Product details
Overview
BZT52H-C3V0,115 from Nexperia is a ±5 % tolerance Zener diode in SOD123F package, designed for precision voltage regulation at 3.0 V nominal breakdown voltage with 500 Ω max differential resistance and ≤0.9 V forward voltage at 10 mA, used in low-power reference and overvoltage protection circuits.
For engineers reviewing the BZT52H-C3V0,115 datasheet, BZT52H-C3V0,115 pinout, BZT52H-C3V0,115 application, or BZT52H-C3V0,115 equivalent, key selection criteria include Zener voltage tolerance (±5 %), thermal resistance (150 K/W junction-to-solder-point), power dissipation (830 mW at Tamb ≤ 25 °C), and SOD123F surface-mount compatibility.
Technical Context
This Zener diode operates in reverse-bias breakdown mode to maintain stable 3.0 V across its terminals under regulated current conditions (IZ = 5 mA), with temperature coefficient of −3.5 mV/K and reverse current ≤10 μA at VR = 1 V. Its SOD123F package enables compact PCB layout while supporting reflow soldering only.
The device exhibits 500 Ω maximum differential resistance at IZ = 5 mA, ensuring predictable dynamic impedance behavior during transient load changes, and supports non-repetitive peak reverse current up to 6.0 A for surge immunity in clamping applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 2.80 V to 3.20 V at IZ = 5 mA - defines regulation window for stable 3.0 V reference |
| Tolerance | ±5 % - determines absolute accuracy of voltage regulation in production designs |
| Differential Resistance (rdif) | ≤500 Ω at IZ = 5 mA - limits output voltage variation under changing load current |
| Forward Voltage (VF) | ≤0.9 V at IF = 10 mA - ensures low conduction loss when used in series bias or polarity protection |
| Total Power Dissipation (Ptot) | 830 mW at Tamb ≤ 25 °C - sets maximum continuous DC power handling on standard FR4 PCB |
| Junction Temperature (Tj) | −65 °C to +150 °C - defines operational envelope for industrial ambient conditions |
| Thermal Resistance (Rth(j-sp)) | 150 K/W - quantifies heat transfer efficiency from junction to cathode solder point |
Pinout & Package
SOD123F is a 2-lead surface-mount plastic package with 3.4–3.6 mm length, 1.5–1.7 mm width, and 0.70–0.55 mm height; cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; marking bar identifies this terminal for correct PCB orientation |
| 2 | Anode (A) | Connected to ground or lower-potential rail; reverse-bias polarity required for Zener operation |
Key Features
| Feature | Design Value |
|---|---|
| Three tolerance options | ±1 %, ±2 %, and ±5 % variants enable cost-performance trade-off in voltage reference design |
| Low-profile SMD package | SOD123F footprint (2.9 × 1.6 mm) supports high-density routing and automated assembly |
| High surge capability | 6.0 A non-repetitive peak reverse current allows transient overvoltage clamping without failure |
| Stable temperature coefficient | −3.5 mV/K at IZ = 5 mA minimizes drift across −65 °C to +150 °C operating range |
| Controlled reverse leakage | ≤10 μA at VR = 1 V ensures minimal quiescent current in battery-powered regulation circuits |
Applications
| Power Supply Reference | Overvoltage Protection |
|---|---|
Use Scenario: Providing stable 3.0 V reference for ADC biasing or comparator threshold in microcontroller-based sensor interfaces. IC Role / Device Role / Timing Role: Zener diode acts as shunt voltage reference, sinking excess current to maintain fixed potential at analog input node. Use Value: ±5 % tolerance and 500 Ω differential resistance ensure <±15 mV deviation under 1 mA load change, meeting 12-bit ADC accuracy requirements. |
Use Scenario: Clamping 3.3 V logic rail against ESD or inductive spikes in industrial I/O modules. IC Role / Device Role / Timing Role: Reverse-biased Zener conducts during overvoltage events, diverting surge current away from sensitive downstream ICs. Use Value: 6.0 A non-repetitive peak reverse current rating absorbs 40 W surges (tp = 100 μs), protecting 3.3 V LDOs and GPIOs. |
| Low-Power Sensor Biasing | Signal Level Translation |
Use Scenario: Generating precise bias voltage for MEMS pressure sensor excitation in portable medical devices. IC Role / Device Role / Timing Role: Zener supplies regulated excitation voltage independent of battery discharge curve. Use Value: 830 mW power rating and −3.5 mV/K temperature coefficient enable stable 3.0 V output across 0–50 °C ambient range with <±5 mV drift. |
Use Scenario: Shifting 5 V microcontroller output to 3.0 V compatible level for interfacing with low-voltage logic. IC Role / Device Role / Timing Role: Forward-biased anode-cathode path drops ~0.9 V, enabling simple level translation without active circuitry. Use Value: ≤0.9 V forward voltage at 10 mA ensures minimal propagation delay and no signal inversion, suitable for static control lines. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZT52B-C3V0,115 | ±2 % tolerance, 95 Ω max rdif at IZ = 5 mA - tighter regulation but higher cost | Better suited for precision reference where <±10 mV error is required | Select when improved voltage stability outweighs cost sensitivity |
| BZX384-C3V0,115 | SOD323 package (2.0 × 1.25 mm), 400 Ω max rdif, same ±5 % tolerance | Smaller footprint but reduced thermal mass limits sustained power handling to 300 mW | Choose for ultra-compact layouts where peak power is <300 mW |
Compared with BZT52H-C3V0,115, the BZT52B-C3V0,115 offers tighter voltage control at higher cost, while the BZX384-C3V0,115 trades thermal performance for board space savings - both require layout and thermal validation before substitution.

FAQ
What is the maximum continuous power dissipation for BZT52H-C3V0,115?
The BZT52H-C3V0,115 has a total power dissipation limit of 830 mW at ambient temperature ≤25 °C when mounted on an FR4 PCB with single-sided copper and a 1 cm² cathode pad. Derating is required above 25 °C per the 150 K/W junction-to-solder-point thermal resistance.
How is polarity identified on the SOD123F package?
The cathode (K) terminal is marked by a visible bar on the top surface of the SOD123F package. Pin 1 (cathode) is located at the bar end; Pin 2 (anode) is at the opposite end. This marking aligns with the simplified outline in Nexperia's datasheet Figure 11.
Does BZT52H-C3V0,115 support wave or hand soldering?
No - reflow soldering is the only recommended method per Nexperia's datasheet. Wave and hand soldering are not qualified due to thermal stress risks on the SOD123F plastic body and internal wire bonds; use the footprint in Figure 12 with standard lead-free reflow profiles.
What is the reverse leakage current at 1 V applied voltage?
At VR = 1 V and Tj = 25 °C, the reverse current (IR) is ≤10 μA, as specified in Table 8 for the BZT52H-C3V0 variant. This low leakage supports energy-efficient operation in battery-backed systems and high-impedance sensing nodes.
