Product details
Overview
BZT52H-C8V2,115 from Nexperia is a ±5 % tolerance Zener diode in SOD123F package, designed for precision voltage regulation and reference applications at 8.2 V nominal breakdown voltage with 150 Ω typical differential resistance at IZ = 5 mA and 830 mW total power dissipation at Tamb ≤ 25 °C. It serves as a stable shunt regulator in low-power analog circuits, power supply feedback paths, and overvoltage protection clamps.
For engineers reviewing the BZT52H-C8V2,115 datasheet, BZT52H-C8V2,115 pinout, BZT52H-C8V2,115 application, or BZT52H-C8V2,115 equivalent, this page delivers verified Zener parameters-including VZ, IZ, rdif, temperature coefficient, and thermal resistance-alongside real-world use cases, pin-confirmed layout guidance, and validated alternative parts for design flexibility.
Technical Context
This Zener diode operates in reverse-biased breakdown mode to maintain a stable 8.2 V reference across load variations, with a temperature coefficient of +3.2 to +6.2 mV/K (typical) ensuring predictable drift under thermal stress. Its SOD123F package enables compact PCB placement while supporting 830 mW steady-state dissipation on standard FR4 with 1 cm² cathode pad.
The device exhibits 150 Ω maximum differential resistance at 5 mA test current, enabling tight regulation in low-current feedback loops, and supports non-repetitive peak reverse currents up to 4.0 A (100 μs pulse), making it suitable for transient suppression in conjunction with series impedance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VZ (Nominal) | 8.2 V - Stable reverse breakdown voltage at IZ = 5 mA, defining primary regulation point |
| Tolerance | ±5 % - Specifies allowable deviation (7.7 V to 8.7 V) for cost-sensitive non-critical references |
| rdif | 150 Ω max - Low dynamic impedance ensures minimal output voltage variation under changing load current |
| Ptot | 830 mW - Maximum continuous power dissipation on FR4 PCB with 1 cm² cathode copper pad |
| IZSM | 4.0 A - Non-repetitive peak reverse surge current capability for transient clamping (100 μs, Tj = 25 °C) |
| SZ | +3.2 to +6.2 mV/K - Positive temperature coefficient enables predictable, monotonic VZ drift with junction heating |
| Rth(j-sp) | 70 K/W - Thermal resistance from junction to solder point confirms effective heat transfer through cathode tab |
Pinout & Package
SOD123F surface-mount plastic package: 2-terminal, flat lead, small outline (3.6 mm × 1.7 mm × 1.0 mm), cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to regulated output node; marking bar identifies this terminal; carries reverse current during regulation |
| 2 (A) | Anode | Connected to ground or lower potential; completes reverse-bias path; must be routed with low-inductance trace for stability |
Key Features
| Feature | Design Value |
|---|---|
| Three tolerance options | ±1 %, ±2 %, and ±5 % variants enable trade-off between precision and cost for different system accuracy tiers |
| Wide voltage range | 2.4 V to 75 V coverage (E24 series) allows single-family reuse across diverse supply rail and reference needs |
| Low-profile SMD package | SOD123F footprint (3.6 mm × 1.7 mm) supports high-density board layouts and automated reflow assembly |
| Thermal performance | Rth(j-sp) = 70 K/W enables reliable operation up to 150 °C junction temperature with proper pad design |
| Transient robustness | 4.0 A non-repetitive IZSM rating permits brief overvoltage clamping without degradation when used with current-limiting resistor |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZT52C8V2,115 | Same SOD123F package and 8.2 V nominal VZ, but ±5 % tolerance (identical); differs only in ordering code suffix - functionally identical part | No functional difference; same use cases and layout compatibility | Select when cross-referencing legacy Nexperia part numbering; no design impact |
| MMBZ5231BS-7-F | 8.2 V ±5 %, SOT-23 package, 350 mW Ptot, 200 Ω rdif; smaller footprint but lower power and higher impedance | Suitable for ultra-low-power (<0.5 mA) references; not recommended for >300 mW dissipation or high-stability feedback | Choose only for space-constrained designs where 350 mW derating and 200 Ω rdif are acceptable |
Compared with BZT52H-C8V2,115, BZT52C8V2,115 is a direct form-fit-function match, while MMBZ5231BS-7-F trades 480 mW lower power headroom and +50 Ω higher impedance for 40 % smaller board area-making it viable only in sub-300 mW, non-critical reference roles.

FAQ
What is the maximum continuous reverse current for BZT52H-C8V2,115 at 25 °C ambient?
The device does not specify a maximum continuous reverse current independent of power dissipation. At Tamb ≤ 25 °C, its 830 mW total power limit implies a maximum steady-state reverse current of approximately 101 mA (830 mW ÷ 8.2 V), assuming operation at nominal VZ. Derating is required above 25 °C per Rth(j-a) = 330 K/W.
Can BZT52H-C8V2,115 replace BZT52B8V2 in an existing design?
Yes, with verification of thermal margin: BZT52H-C8V2,115 has identical 8.2 V nominal VZ and ±5 % tolerance as BZT52B8V2, but offers higher Ptot (830 mW vs. 375 mW) and lower rdif (150 Ω vs. ~170 Ω). Layout remains compatible (SOD123F), but thermal relief may be reduced due to improved dissipation capability.
What is the reverse leakage current at 6.0 V for BZT52H-C8V2,115?
Per Table 8, the maximum reverse current IR at VR = 6.0 V is 0.7 μA (typical value not specified; only max given). This low leakage ensures minimal quiescent power loss in high-impedance reference networks and preserves accuracy in battery-operated systems.
Is BZT52H-C8V2,115 qualified for automotive applications?
No. Per Revision History (Section 13), the BZT52H series was changed to non-automotive qualification in Rev. 7 (Jan 2023). Automotive alternatives are designated with "-Q" suffix (e.g., BZT52H-C8V2-Q) and require separate qualification documentation; this part is intended for industrial, consumer, and computing use only.
