Product details
Overview
BZT52HC5V6WF-7 from Diodes Incorporated is a surface-mount Zener diode with nominal 5.6 V zener voltage (5.2–6.0 V range), 40 Ω zener impedance at 5 mA test current, −2.0 to +2.5 mV/°C temperature coefficient, 300 pF capacitance at 1 MHz, and 1 µA maximum reverse leakage at 2 V. It operates in SOD123F package and serves as precision voltage reference or overvoltage clamp in low-power analog signal conditioning circuits.
For engineers reviewing the BZT52HC5V6WF-7 datasheet, BZT52HC5V6WF-7 pinout, BZT52HC5V6WF-7 application, or BZT52HC5V6WF-7 equivalent, key selection criteria include zener voltage tolerance, thermal coefficient stability across −65°C to +150°C, low-capacitance clamping for high-frequency signal paths, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This Zener diode uses planar epitaxial construction to achieve tight voltage regulation and low dynamic impedance. Its −2.0 to +2.5 mV/°C temperature coefficient enables stable reference performance across industrial temperature ranges without external compensation.
The SOD123F package provides 375 mW power dissipation on standard FR-4 PCBs and up to 830 mW with enhanced cathode pad area. Reverse leakage remains ≤1 µA at VR = 2 V, supporting low-current biasing and standby-mode protection functions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.2–6.0 V at IZT = 5 mA - defines regulated output voltage window under nominal bias |
| Zener Impedance (ZZT) | 40 Ω at IZT = 5 mA - ensures minimal voltage deviation during load transients |
| Temperature Coefficient | −2.0 to +2.5 mV/°C at IZT = 5 mA - enables predictable drift behavior for temperature-critical references |
| Capacitance (CT) | 300 pF at f = 1 MHz, VR = 0 V - supports use in <10 MHz signal path clamping without excessive loading |
| Reverse Leakage (IR) | 1 µA max at VR = 2 V - maintains low quiescent current in battery-powered monitoring circuits |
| Power Dissipation (PD) | 375 mW (standard layout) / 830 mW (enhanced pad) - determines thermal design margin for continuous operation |
| Operating Temperature | −65°C to +150°C - validated for under-hood automotive and industrial control environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMSZ5232B-TP (Micro Commercial) | Zener voltage 5.6 V ±5%, ZZT = 15 Ω @ 20 mA, no AEC-Q101 rating | Higher test current shifts operating point; unsuitable for automotive under-hood use | Select when cost sensitivity outweighs automotive qualification and low-current stability needs |
| BZX84-C5V6 (Nexperia) | SOT-23 package, 5.6 V ±5%, ZZT = 60 Ω @ 5 mA, AEC-Q101 qualified | Larger footprint and 150 mW PD limit use in high-power clamping roles | Prefer for designs already using SOT-23 footprints or requiring tighter voltage tolerance at higher currents |
Compared with MMSZ5232B-TP and BZX84-C5V6, BZT52HC5V6WF-7 delivers superior low-current regulation stability (40 Ω @ 5 mA), higher power handling (375 mW), and optimized SOD123F thermal performance-making it ideal for automotive sensor references where precision and thermal resilience are critical.

FAQ
What is the maximum power dissipation of BZT52HC5V6WF-7 under standard PCB layout?
The device dissipates up to 375 mW when mounted on an FR-4 PCB using Diodes Incorporated's minimum recommended pad layout. This value assumes natural convection cooling and accounts for thermal resistance of 330°C/W junction-to-ambient. Exceeding this limit risks thermal runaway and parametric shift.
Does BZT52HC5V6WF-7 support lead-free reflow soldering?
Yes. Its matte tin-annealed copper alloy leadframe meets MIL-STD-202 Method 208 solderability requirements and is rated for lead-free reflow profiles per J-STD-020 Level 1 (unlimited floor life, peak temperature up to 260°C). No pre-baking is required.
How does the temperature coefficient affect voltage regulation accuracy?
With a specified coefficient of −2.0 to +2.5 mV/°C, the zener voltage drifts linearly across temperature. Over a 100°C span, worst-case deviation is ±0.25 V-critical for applications requiring better than ±1% regulation must include thermal compensation or operate within narrower ambient bands.
Can BZT52HC5V6WF-7 be used in bidirectional ESD protection configurations?
Yes-when paired with a second identical device anode-to-anode, it forms a symmetrical clamp for data lines. Each device conducts in reverse above 5.6 V, limiting differential swing to ~11.2 V while maintaining 300 pF total capacitance per line, suitable for USB 2.0 and RS-485 interfaces.
