Product details
Overview
BZT52H-C2V7,115 from Nexperia is a ±5 % tolerance Zener diode in SOD123F package, rated for 2.7 V nominal breakdown voltage at 5 mA, with 830 mW total power dissipation and 500 Ω maximum differential resistance, used for precision voltage reference and overvoltage protection in low-power analog circuits.
For engineers reviewing the BZT52H-C2V7,115 datasheet, BZT52H-C2V7,115 pinout, BZT52H-C2V7,115 application, or BZT52H-C2V7,115 equivalent, this page delivers verified Zener parameters, thermal performance under PCB mounting conditions, cathode/anode terminal mapping, and direct-fit alternatives for 2.7 V regulation in space-constrained SMD designs.
Technical Context
This Zener operates in reverse-biased breakdown mode with a temperature coefficient of –3.5 to 0.0 mV/K at IZ = 5 mA, enabling stable reference generation across –65 °C to +150 °C ambient range. Its 450 pF capacitance at 0 V and 20 μA reverse current at 1 V support low-frequency regulation without signal coupling issues.
The device uses silicon planar technology with metallized cathode termination, optimized for reflow soldering on FR4 PCBs with single-sided copper and tin plating. Thermal resistance from junction to solder point is 70 K/W, confirming suitability for thermally constrained layouts where heat spreading is limited.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage (VZ) | 2.50 V to 2.90 V at IZ = 5 mA - defines usable regulation window for 2.7 V nominal rail stabilization |
| Differential Resistance (rdif) | 500 Ω max - limits output impedance drift under load variation, critical for reference stability |
| Total Power Dissipation (Ptot) | 830 mW at Tamb ≤ 25 °C on 1 cm² cathode pad - sets maximum continuous DC power before thermal derating |
| Forward Voltage (VF) | 0.9 V max at IF = 10 mA - ensures low conduction loss when used as clamp or ESD path in forward bias |
| Reverse Current (IR) | 20 μA max at VR = 1 V - guarantees minimal leakage below knee voltage, preserving battery life in standby |
| Junction Temperature (Tj) | 150 °C max - determines maximum allowable internal operating temperature under worst-case power/ambient conditions |
| Package | SOD123F - 3.6 mm × 1.2 mm footprint with flat leads, compatible with standard 0805 reflow profiles |
Pinout & Package
SOD123F is a surface-mount plastic package with two terminals: cathode (K) marked by a bar on the body, and anode (A). The package measures 3.6 mm × 1.2 mm × 1.0 mm and is designed for automated placement and reflow soldering on FR4 PCBs.
| 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 ground or lower-potential rail; completes bias path for reverse breakdown conduction |
Key Features
| Feature | Design Value |
|---|---|
| ±5 % VZ tolerance | Enables cost-optimized selection for non-critical 2.7 V references where tight regulation is not required |
| 830 mW power rating | Supports higher-current shunt regulation than standard 500 mW Zeners, reducing need for external series resistors |
| Low 500 Ω rdif | Maintains <1 % output voltage shift across 1 mA load change, improving line regulation in feedback paths |
| SOD123F footprint | Reduces board area by 30 % vs. DO-214AC while retaining mechanical robustness for high-volume assembly |
| –65 °C to +150 °C operation | Validates use in industrial control modules and automotive under-hood auxiliary circuits (non-automotive qualified) |
Applications
| Power Supply Reference | Overvoltage Clamp |
|---|---|
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZT52C2V7,115 | Same SOD123F package and 2.7 V nominal VZ, but ±5 % tolerance (identical); identical thermal specs and pinout | No functional difference; alternate ordering code for same device family | Select when cross-referencing legacy BOMs or distributor stock codes |
| MMBZ5223BS-7-F | 2.7 V nominal, ±5 %, SOT-23 package; 350 mW Ptot; 600 Ω rdif; 100 °C max Tj | Lower power rating and thermal limit restrict use to sub-100 mA regulation; smaller footprint increases layout density | Choose only if board space is constrained and power demand stays below 200 mW |
Compared with BZT52H-C2V7,115, BZT52C2V7,115 offers identical electrical and thermal behavior with no design impact, while MMBZ5223BS-7-F trades 35 % lower power handling and reduced thermal margin for 40 % smaller footprint-making it viable only in ultra-low-power, space-limited roles.

FAQ
What is the maximum reverse current at 1 V for BZT52H-C2V7,115?
The maximum reverse current (IR) is 20 μA at VR = 1 V and Tj = 25 °C, per Table 8 of the datasheet. This low leakage ensures minimal power drain in always-on circuits and supports accurate threshold detection in comparator-based protection schemes.
Can BZT52H-C2V7,115 be used in automotive applications?
No-this part is explicitly marked as non-automotive qualified in the revision history (Rev. 7, January 2023). It lacks AEC-Q200 qualification and has not undergone automotive-grade stress testing; Nexperia recommends its -Q automotive series for under-hood or safety-critical systems.
What is the thermal resistance from junction to solder point?
Rth(j-sp) is 70 K/W, measured at the cathode solder point under specified mounting conditions (FR4 PCB, single-sided copper, tin-plated, 1 cm² cathode pad), enabling accurate junction temperature estimation during thermal design.
How does the temperature coefficient affect regulation accuracy?
With a temperature coefficient of –3.5 to 0.0 mV/K at IZ = 5 mA, the breakdown voltage shifts up to –0.53 mV/°C over the full –65 °C to +150 °C range, resulting in ±117 mV total drift-acceptable for non-precision references but requiring compensation in high-stability designs.
