Product details
Overview
BZT52H-B5V1,115 from Nexperia is a ±2 % tolerance Zener diode in SOD123F package, rated for 5.1 V nominal breakdown voltage at IZ = 5 mA, with 830 mW total power dissipation and 60 Ω maximum differential resistance - used for precision voltage reference and overvoltage protection in low-power DC rails.
For engineers reviewing the BZT52H-B5V1,115 datasheet, BZT52H-B5V1,115 pinout, BZT52H-B5V1,115 application, or BZT52H-B5V1,115 equivalent, this part supports stable regulation in space-constrained PCBs where thermal resistance to solder point (150 K/W) and low reverse leakage (<2 μA at 3.8 V) are critical selection criteria.
Technical Context
This Zener diode operates in reverse-biased avalanche mode with tightly controlled VZ tolerance (±2 %), enabling accurate clamping in feedback loops and reference circuits. Its 5.1 V nominal working voltage falls within the E24 series and exhibits a positive temperature coefficient of +1.2 mV/K at IZ = 5 mA.
The device uses silicon planar technology in a small-outline SMD package optimized for reflow soldering. Thermal resistance from junction to solder point is 150 K/W, and it sustains non-repetitive peak reverse current up to 6.0 A under 100 μs pulses at Tamb = 25 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage (VZ) | 5.00 V to 5.20 V at IZ = 5 mA - defines precise clamping threshold for 5 V rail stabilization |
| Differential Resistance (rdif) | ≤ 60 Ω - ensures minimal voltage shift under load current variation in regulation circuits |
| Reverse Leakage (IR) | < 2 μA at VR = 3.8 V - guarantees low quiescent current in standby-mode protection networks |
| Total Power Dissipation (Ptot) | 830 mW at Tamb ≤ 25 °C - sets maximum continuous DC power handling on standard FR4 PCB |
| Forward Voltage (VF) | ≤ 0.9 V at IF = 10 mA - confirms low conduction loss when used bidirectionally or as ESD clamp |
| Temperature Coefficient (SZ) | +1.2 mV/K at IZ = 5 mA - enables predictable drift compensation in temperature-sensitive references |
| Junction Temperature Range | –65 °C to +150 °C - supports operation in industrial ambient environments without derating |
Pinout & Package
SOD123F is a surface-mount plastic package with two leads, 3.4–3.6 mm length, 1.5–1.7 mm width, and 0.7–0.85 mm height. Cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; reverse-bias anode-to-ground configuration enables voltage clamping |
| 2 | Anode (A) | Typically tied to ground or lower-potential rail; polarity must be observed to avoid forward conduction during regulation |
Key Features
| Feature | Design Value |
|---|---|
| ±2 % VZ tolerance | Enables tighter regulation than ±5 % variants, reducing need for post-production trimming in reference designs |
| 830 mW power rating | Supports higher sustained current than standard 500 mW Zeners, allowing use in moderate-current shunt regulators |
| SOD123F footprint | Compatible with automated placement and reflow; occupies only 5.8 mm² PCB area - ideal for dense consumer PCBs |
| Low rdif (60 Ω max) | Minimizes output voltage deviation across 1–10 mA load range, improving stability in feedback-sensing applications |
| 150 K/W Rth(j-sp) | Enables direct thermal coupling to copper pour, permitting reliable operation without heatsinking at ≤300 mW |
Applications
| Power Supply Voltage Reference | Overvoltage Clamp for MCU I/O |

Use Scenario: Providing stable 5.1 V reference for ADC voltage dividers and op-amp bias networks in battery-powered sensors. IC Role / Device Role / Timing Role: Zener diode functions as two-terminal shunt reference, replacing bulkier IC references where 1 % absolute accuracy is not required. Use Value: Delivers <2 μA leakage and 60 Ω dynamic impedance, ensuring reference stability across –40 °C to +85 °C without active compensation. |
Use Scenario: Protecting 5 V-tolerant GPIO pins of microcontrollers against transient surges from nearby switching loads. IC Role / Device Role / Timing Role: Acts as fast-acting crowbar element, clamping voltage spikes above 5.2 V before damage occurs to input protection diodes. Use Value: With 6.0 A non-repetitive surge rating and 100 μs pulse capability, it absorbs >40 W peak energy without failure. |
| Low-Cost LDO Feedback Divider | Industrial Sensor Signal Conditioning |
|
Use Scenario: Setting output voltage of adjustable LDOs (e.g., TLV733 series) via resistor divider anchored to a stable Zener node. IC Role / Device Role / Timing Role: Replaces internal bandgap reference with external precision node, enabling programmable output voltages with ±0.1 V accuracy. Use Value: ±2 % VZ tolerance and +1.2 mV/K TC allow predictable output drift tracking - critical for factory-calibrated sensor modules. |
Use Scenario: Biasing bridge amplifiers and conditioning analog outputs of pressure/temperature transducers in 4–20 mA loop interfaces. IC Role / Device Role / Timing Role: Supplies clean, low-noise 5.1 V excitation to Wheatstone bridges while rejecting supply ripple through high PSRR inherent to shunt topology. Use Value: 300 pF capacitance at 0 V and <2 μA IR ensure minimal signal distortion and offset drift in µV-level measurement paths. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZT52C5V1,115 | ±5 % VZ tolerance; same SOD123F package and 830 mW rating | Acceptable where cost sensitivity outweighs tight regulation needs; higher VZ spread increases calibration burden | Select when budget constraints dominate and system-level trimming is available |
| MMSZ5222BS-7-F | ±5 % tolerance; SOD-123 package (not SOD123F); 500 mW Ptot; 170 Ω rdif | Limited to lower-power clamping; higher impedance reduces regulation fidelity in dynamic loads | Choose only if legacy footprint compatibility is mandatory and power <300 mW |
Compared with BZT52H-B5V1,115, the ±5 % alternatives trade regulation precision and thermal performance for lower unit cost, while the MMSZ5222BS lacks both the tight tolerance and power capability needed for robust industrial reference use.

FAQ
What is the maximum continuous reverse current this Zener can handle at 25 °C ambient?
At Tamb = 25 °C on a standard FR4 PCB with single-sided copper, the BZT52H-B5V1,115 supports up to 163 mA continuous reverse current (calculated as 830 mW ÷ 5.1 V), assuming negligible forward drop and no thermal derating. Derating begins above 25 °C per the 150 K/W Rth(j-sp) value.
Can this diode be used in series to achieve higher reference voltages?
Yes - multiple BZT52H-B5V1,115 units may be stacked in series to generate higher reference voltages (e.g., 10.2 V with two devices), but tolerance accumulates linearly (±4 % for two), and thermal coupling between devices must be managed to avoid mismatched drift. Parallel connection is not recommended due to VZ mismatch.
Is the SOD123F package compatible with standard reflow profiles?
Yes - Nexperia specifies reflow soldering as the only recommended method for SOD123F. The package withstands peak temperatures up to 260 °C for ≤10 seconds, matching IPC/JEDEC J-STD-020D. Footprint dimensions (2.9 × 1.6 mm pad layout) are defined in Figure 12 of the datasheet.
How does its temperature coefficient affect long-term reference stability?
With +1.2 mV/K at IZ = 5 mA, the BZT52H-B5V1,115 exhibits predictable positive drift: a 50 °C rise from 25 °C increases VZ by ~60 mV (1.2 %). For high-stability applications, this requires either temperature compensation circuitry or operation within a narrow ambient band (e.g., 0–40 °C).
