Product details
Overview
BZT52HC6V2WF-7 from Diodes Incorporated is a surface-mount Zener diode with nominal 6.2 V zener voltage, 5 mA test current, and 10 Ω dynamic impedance at 5 mA. It features SOD123F (Type B) package, AEC-Q101 qualification for automotive reliability, and operates across −65 °C to +150 °C. Used for precision voltage regulation and overvoltage protection in power supply feedback loops.
For engineers reviewing the BZT52HC6V2WF-7 datasheet, BZT52HC6V2WF-7 pinout, BZT52HC6V2WF-7 application, or BZT52HC6V2WF-7 equivalent, key selection criteria include zener voltage tolerance (±6.5% at 6.2 V), low thermal resistance (150 °C/W with 1 cm² cathode pad), temperature coefficient (+0.4 to +3.7 mV/°C), and AEC-Q101 compliance for automotive-grade designs.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable reference voltage under varying load and temperature conditions. Its 6.2 V nominal zener voltage is specified at IZT = 5 mA, with dynamic impedance of 10 Ω and knee impedance of 150 Ω at IZK = 1 mA - enabling accurate regulation even at low currents.
The device uses a planar epitaxial construction with cathode band polarity marking and matte tin–annealed copper alloy leadframe. Thermal performance is defined for two mounting conditions: 330 °C/W on minimal FR-4 pad (375 mW rating) and 150 °C/W with 1 cm² cathode pad (830 mW rating), supporting flexible PCB layout strategies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.8 V to 6.6 V at IZT = 5 mA - ensures ±6.5% tolerance for stable 6.2 V reference in feedback networks. |
| Zener Impedance (ZZT) | 10 Ω at IZT = 5 mA - low dynamic resistance minimizes output voltage variation under load transients. |
| Temperature Coefficient (TC) | +0.4 to +3.7 mV/°C - positive TC enables predictable drift compensation in temperature-critical references. |
| Power Dissipation (PD) | 830 mW with 1 cm² cathode pad - supports higher continuous power in thermally optimized layouts. |
| Reverse Leakage (IR) | 3 µA max at VR = 4 V - low leakage preserves accuracy in high-impedance bias networks. |
| Capacitance (CT) | 200 pF max at f = 1 MHz, VR = 0 V - limits high-frequency noise coupling in analog signal paths. |
| Operating Temperature | −65 °C to +150 °C - qualified per AEC-Q101, suitable for under-hood automotive and industrial environments. |
Pinout & Package
Package: SOD123F (Type B), flat-lead surface-mount package with cathode band marking. Dimensions: 1.80 mm × 2.70 mm × 1.15 mm (L × W × H), weight ≈ 0.015 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMSZ5234B-7-F (Diodes Inc.) | Same 6.2 V nominal, but SOD-123 package (not SOD123F); 100 Ω ZZT, 500 mW PD, no AEC-Q101 qualification. | Lacks automotive qualification and thermal performance; suited for consumer-grade power supplies only. | Select when AEC-Q101 is not required and board space allows standard SOD-123 footprint. |
| BZX84-C6V2 (Nexperia) | 6.2 V nominal, SOT-23 package; 60 Ω ZZT, 300 mW PD, AEC-Q101 qualified but higher ZZT and lower power rating. | Higher impedance limits regulation accuracy in precision feedback; lower PD restricts use in high-current shunt designs. | Choose only if SOT-23 footprint is mandatory and thermal budget permits reduced power handling. |
Compared with MMSZ5234B-7-F and BZX84-C6V2, BZT52HC6V2WF-7 delivers superior thermal performance (830 mW vs. ≤500 mW), lower dynamic impedance (10 Ω vs. ≥60 Ω), and full AEC-Q101 validation - making it the preferred choice for automotive and industrial systems demanding long-term voltage stability under thermal stress.

FAQ
What is the maximum power dissipation of BZT52HC6V2WF-7 under standard PCB mounting?
The device delivers 375 mW maximum power dissipation when mounted on an FR-4 PCB with Diodes Incorporated's minimum recommended pad layout (RθJA = 330 °C/W). This value increases to 830 mW when the cathode pad area is extended to 1 cm² (RθJA = 150 °C/W), as verified in the DS36891 Rev. 4-2 datasheet Figure 1 derating curve.
Does BZT52HC6V2WF-7 have a specified forward voltage?
Yes - the forward voltage is specified as 0.9 V maximum at IF = 10 mA (DS36891 Rev. 4-2, page 2). This parameter is relevant for reverse-polarity protection configurations where the diode conducts forward during fault conditions, ensuring low-voltage drop and minimal power loss.
How is polarity identified on the BZT52HC6V2WF-7 package?
Polarity is marked by a visible cathode band on the SOD123F package body. The band denotes the cathode terminal, which must be connected to the higher-potential node in Zener regulation applications. This marking aligns with JEDEC-standard SOD123F mechanical drawings and is confirmed in the "Terminal Connections" section of DS36891.
Is BZT52HC6V2WF-7 suitable for use in life support equipment?
No - Diodes Incorporated explicitly prohibits use of this product in life support devices or systems without express written approval from its CEO, as stated in the "LIFE SUPPORT" notice on page 5 of DS36891 Rev. 4-2. It is not certified for implantable or critical-safety applications per ISO 13485 or IEC 62304 requirements.
