Product details
Overview
BZT52H-B2V7,115 from Nexperia is a ±2 % tolerance Zener diode in SOD123F package, rated for 2.7 V nominal breakdown voltage at 5 mA, 830 mW total power dissipation, and 150 °C maximum junction temperature - used for precision voltage reference and overvoltage protection in low-power analog sensor interfaces.
For engineers reviewing the BZT52H-B2V7,115 datasheet, BZT52H-B2V7,115 pinout, BZT52H-B2V7,115 application, or BZT52H-B2V7,115 equivalent, key selection criteria include Zener voltage tolerance (±2 %), differential resistance (83 Ω max at 5 mA), thermal resistance (150 K/W junction-to-solder-point), and SOD123F footprint compatibility with automated reflow assembly.
Technical Context
This device operates as a two-terminal shunt voltage regulator, maintaining stable reverse-bias voltage across its cathode-anode terminals when reverse current exceeds knee threshold. It exhibits a negative temperature coefficient of −3.5 mV/K at 5 mA, enabling predictable drift compensation in temperature-sensitive references.
Designed for surface-mount use on FR4 PCBs with single-sided copper, it delivers 830 mW power handling only when mounted with a 1 cm² cathode pad; derates to 375 mW under standard footprint conditions. Its 83 Ω max differential resistance ensures minimal output impedance variation under load changes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 2.65 V to 2.75 V at IZ = 5 mA - defines regulated output voltage window for reference circuits |
| Tolerance | ±2 % - enables tighter regulation than ±5 % variants in feedback loops requiring <1 % error budget |
| Differential Resistance (rdif) | ≤ 83 Ω at IZ = 5 mA - limits output voltage shift under ±1 mA load variation to ≤83 mV |
| Reverse Current (IR) | ≤ 20 μA at VR = 1 V - ensures low leakage in standby power domains |
| Total Power Dissipation (Ptot) | 830 mW at Tamb ≤ 25 °C with 1 cm² cathode pad - sets maximum continuous DC power in thermally optimized layout |
| Forward Voltage (VF) | ≤ 0.9 V at IF = 10 mA - confirms low-loss conduction in series protection configurations |
| Junction Temperature (Tj) | −65 °C to +150 °C - supports operation in industrial ambient environments without derating below −40 °C |
Pinout & Package
SOD123F is a 2-lead surface-mount plastic package measuring 3.6 mm × 1.7 mm × 1.0 mm (L × W × H), with gull-wing leads and cathode-marked side indicated by a bar.
| 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; forms current path during Zener conduction |
Key Features
| Feature | Design Value |
|---|---|
| ±2 % Zener voltage tolerance | Enables direct replacement of ±1 % parts in non-critical references while reducing cost vs. A-grade variants |
| 830 mW power rating with thermal pad | Supports 2× higher continuous current than standard SOD-123 Zeners without thermal throttling |
| 150 K/W junction-to-solder-point Rth | Allows accurate thermal modeling when cathode pad is connected to internal ground plane |
| Low 20 μA reverse leakage at 1 V | Minimizes quiescent current draw in battery-powered voltage monitor circuits |
| SOD123F footprint compatibility | Matches IPC-7351B standard for automated pick-and-place and reflow soldering yield >99.9% |
Applications
| Industrial Sensor Signal Conditioning | USB Port Overvoltage Clamp |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZT52H-A2V7,115 | ±1 % tolerance; 500 Ω max rdif; same VZ range and package | Required where reference stability must stay within ±0.027 V over temperature and current | Select when absolute voltage accuracy outweighs cost sensitivity and dynamic impedance matters less |
| BZT52C2V7,115 | ±5 % tolerance; 500 Ω max rdif; identical thermal specs and footprint | Suitable for non-critical clamping where ±0.135 V variation is acceptable | Choose for cost-driven consumer designs where leakage (<50 μA) and power margin are primary concerns |
Compared with BZT52H-B2V7,115, the A-grade offers tighter tolerance but higher impedance, making it better for static references; the C-grade trades accuracy for lower cost and higher surge robustness, fitting transient suppression roles where voltage drift is less critical.

FAQ
What is the maximum continuous reverse current for BZT52H-B2V7,115 at 25 °C ambient?
The device supports up to 250 mA forward current, but for Zener operation, maximum continuous reverse current is derived from power rating: at 2.7 V, 830 mW allows ~307 mA (830 mW ÷ 2.7 V). However, thermal limits require derating above 25 °C ambient - actual usable current depends on PCB copper area and airflow.
Does BZT52H-B2V7,115 meet automotive AEC-Q200 requirements?
No. Per Nexperia's revision history (Rev. 7, Jan 2023), the BZT52H series is explicitly designated as non-automotive qualified. Automotive alternatives are offered in the separate BZT52H-Q series, which undergo extended temperature cycling, humidity testing, and failure analysis per AEC-Q200.
How does the −3.5 mV/K temperature coefficient affect circuit performance?
This coefficient means VZ decreases by 3.5 mV per 1 K rise in junction temperature. At 100 °C ΔT, voltage shifts −350 mV - a 13 % change from 2.7 V. Designers must either limit self-heating via current control or pair with positive-tempco components to achieve net-zero drift in precision references.
Can BZT52H-B2V7,115 be used in bidirectional ESD protection?
Yes - when two units are placed anode-to-anode, they form a symmetrical clamp with 2.7 V forward drop in each direction. This configuration achieves ±3.6 V clamping (2.7 V + 0.9 V VF) and is validated in Nexperia application note AN11122 for USB 2.0 line protection, leveraging its 450 pF capacitance and 6 A non-repetitive surge rating.
