Product details
Overview
BZT52H-B6V2,115 from Nexperia is a ±2 % tolerance Zener diode in SOD123F package, rated for 6.2 V nominal breakdown voltage at IZ = 5 mA, with 150 Ω typical differential resistance, 3 μA max reverse current at VR = 4.96 V, and 830 mW total power dissipation at Tamb ≤ 25 °C - used for precision voltage reference and overvoltage clamping in low-power analog signal conditioning circuits.
For engineers reviewing the BZT52H-B6V2,115 datasheet, BZT52H-B6V2,115 pinout, BZT52H-B6V2,115 application, or BZT52H-B6V2,115 equivalent, key selection criteria include Zener voltage tolerance (±2 %), thermal resistance (150 K/W junction-to-solder-point), cathode-anode polarity marking, SOD123F footprint compatibility, and non-automotive qualification status per Rev. 7 (Jan 2023).
Technical Context
This device operates as a two-terminal voltage reference diode, conducting in reverse bias above its specified Zener voltage (6.2 V) with tightly controlled dynamic impedance (150 Ω typ.) and low temperature coefficient (+0.4 to +3.7 mV/K). It exhibits stable regulation under DC and low-frequency transient conditions up to 250 mA forward current and 40 W non-repetitive peak reverse power.
Designed for surface-mount use on FR4 PCBs with single-sided copper, it relies on defined thermal mounting (1 cm² cathode pad) to achieve rated 830 mW power dissipation and 150 °C maximum junction temperature - performance validated per IEC 60134 absolute maximum ratings.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.08 V to 6.32 V at IZ = 5 mA - defines precise clamping threshold for 6.2 V nominal rail regulation |
| Tolerance | ±2 % - enables tighter output voltage control than ±5 % variants in feedback loops |
| Differential Resistance (rdif) | 150 Ω max - determines regulation stiffness and load-induced voltage deviation |
| Reverse Current (IR) | 3 μA max at VR = 4.96 V - ensures minimal leakage in standby or high-impedance sensing nodes |
| Total Power Dissipation (Ptot) | 830 mW at Tamb ≤ 25 °C with 1 cm² cathode pad - sets continuous DC power handling limit |
| Forward Voltage (VF) | 0.9 V max at IF = 10 mA - defines conduction loss when used in series forward configuration |
| Junction Temperature (Tj) | −65 °C to +150 °C - specifies operational thermal envelope for industrial ambient environments |
Pinout & Package
SOD123F is a small-outline, flat-lead, surface-mounted plastic package with 2 terminals and standardized reflow footprint (2.9 mm × 1.6 mm occupied area); cathode marked by a bar on the device body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; marking bar identifies this terminal; carries reverse current during Zener operation |
| 2 | Anode (A) | Connected to reference ground or lower-potential rail; completes reverse-bias path for voltage regulation |
Key Features
| Feature | Design Value |
|---|---|
| Power rating | 830 mW at Tamb ≤ 25 °C with defined PCB copper area - supports higher continuous current than standard 500 mW Zeners |
| Voltage tolerance | ±2 % option - reduces variation in feedback networks versus ±5 % parts, improving system-level accuracy |
| Thermal resistance | 150 K/W junction-to-solder-point - enables predictable derating curves for thermal design on standard FR4 |
| Package size | SOD123F (3.6 mm × 1.7 mm × 1.0 mm) - fits high-density layouts while maintaining hand-solderability and AOI inspectability |
| Non-repetitive surge | 6.0 A IZSM at tp = 100 μs - provides transient overvoltage immunity without external TVS staging |
Applications
| Power Supply Reference | Signal Level Clamping |
|---|---|
Use Scenario: Stabilizing feedback voltage in low-current linear regulators or op-amp reference inputs. IC Role / Device Role: Provides fixed 6.2 V reference point for error amplifier comparison. Use Value: ±2 % tolerance ensures output voltage drift remains within ±12.4 mV across production units. |
Use Scenario: Limiting analog sensor output swing to protect ADC input stages. IC Role / Device Role: Shunts excess voltage above 6.2 V to ground during transients. Use Value: 150 Ω rdif limits clamping error to <150 mV at 1 mA overvoltage current. |
| Microcontroller Reset Circuit | ESD-Sensitive Interface Protection |
Use Scenario: Generating clean reset pulse during power-up or brown-out in embedded systems. IC Role / Device Role: Holds reset line low until supply reaches stable 6.2 V threshold. Use Value: Low 3 μA IR prevents premature release due to leakage in RC timing network. |
Use Scenario: Protecting UART or I²C lines from electrostatic discharge events. IC Role / Device Role: Absorbs ESD energy by entering Zener conduction before IC damage threshold. Use Value: 6.0 A non-repetitive surge rating handles IEC 61000-4-2 Level 4 contact discharge (8 kV) pulses. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZT52C6V2,115 | ±5 % tolerance, 100 Ω rdif, same SOD123F package | Higher voltage variation acceptable in cost-sensitive power rails | Select when ±5 % regulation accuracy suffices and lower BOM cost is prioritized |
| MMSZ5234B-7-F | ±5 % tolerance, 6.2 V nominal, SOD-123 package, 500 mW Ptot | Limited power handling requires derating above 70 °C ambient | Choose only for legacy designs where MMSZ footprint compatibility is mandatory |
Compared with BZT52H-B6V2,115, the BZT52C6V2,115 trades tighter voltage control for lower unit cost, while MMSZ5234B-7-F sacrifices 330 mW of power margin and lacks the 150 K/W Rth(j-sp) thermal spec needed for thermally constrained PCBs.

FAQ
What is the marking code for BZT52H-B6V2,115?
The marking code for BZT52H-B6V2,115 is "DN", printed on the cathode side of the SOD123F package. This two-character code uniquely identifies the 6.2 V ±2 % variant within the BZT52H series and matches Table 4 in the Rev. 7 datasheet. The bar adjacent to the marking denotes the cathode terminal.
Can BZT52H-B6V2,115 be used in automotive applications?
No - BZT52H-B6V2,115 is explicitly designated as non-automotive qualified per Rev. 7 (Jan 2023) revision history. It has not undergone AEC-Q101 stress testing or automotive-grade process controls. For automotive use, Nexperia offers separate -Q qualified variants; this part must not be deployed in safety-critical or vehicle subsystems.
What is the maximum reverse current at 4.96 V?
The maximum reverse current (IR) for BZT52H-B6V2,115 at VR = 4.96 V is 3 μA, specified in Table 8 under "Reverse current IR (μA)" for the B-series 6.2 V type. This value is measured at Tj = 25 °C and defines leakage behavior below the Zener knee, critical for high-impedance bias networks.
How does thermal resistance affect power derating?
With Rth(j-sp) = 150 K/W (junction-to-solder-point), power must be linearly derated above 25 °C ambient: Ptot = 830 mW − [(Tamb − 25) × 5.53 mW/°C]. At 70 °C ambient, usable power drops to ~580 mW. This derating curve assumes the cathode pad is soldered to a 1 cm² copper area as defined in Table 5 footnote [3].
