Product details
Overview
BZT52C6V2T-7 from Diodes Incorporated is a surface-mount Zener diode with nominal zener voltage 6.2 V, 5 mA test current, 10 Ω maximum zener impedance at 5 mA, 300 mW power dissipation, and SOD523 package. It provides precise voltage regulation in low-power biasing, reference, and overvoltage protection circuits for consumer and industrial electronics.
For engineers reviewing the BZT52C6V2T-7 datasheet, BZT52C6V2T-7 pinout, BZT52C6V2T-7 application, or BZT52C6V2T-7 equivalent, key selection criteria include zener voltage tolerance (±6.5% at 6.2 V), low dynamic impedance (10 Ω), thermal resistance (417 °C/W), and JEDEC-qualified reliability for non-automotive embedded systems.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable voltage across its terminals under varying load or supply conditions. Its 6.2 V nominal zener voltage exhibits a near-zero temperature coefficient (0.4 mV/°C) and supports regulation within ±0.4 V over -55°C to +150°C operating range.
The device uses alloy 42 leadframe with matte tin annealed finish, rated for 300 mW at 25°C ambient and derated linearly above 25°C per the published power derating curve. Reverse leakage remains ≤3.0 µA at 4.0 V, enabling low-quiescent-current reference designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.2 V nominal, 5.8–6.6 V range at 5 mA - ensures tight regulation for 5 V rail monitoring and feedback loops |
| Power Dissipation (PD) | 300 mW at TA = 25°C - supports continuous operation in compact PCB layouts without forced cooling |
| Zener Impedance (ZZT) | 10 Ω max at 5 mA - minimizes output voltage variation under dynamic load transients |
| Reverse Leakage (IR) | ≤3.0 µA at VR = 4.0 V - preserves accuracy in high-impedance reference nodes |
| Thermal Resistance (RθJA) | 417 °C/W - defines junction-to-ambient rise per watt; requires minimal copper area for thermal management |
| Operating Temperature | -55°C to +150°C - suitable for extended-temperature industrial and outdoor applications |
| Package | SOD523 - 1.2 mm × 0.8 mm footprint, 0.6 mm height; compatible with standard 0402 reflow profiles |
Pinout & Package
Package: SOD523 - ultra-compact surface-mount plastic package with cathode band marking; dimensions: 1.25 mm (E) × 0.85 mm (D) × 0.65 mm (A max); weight ≈ 0.001 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal / Zener cathode reference node | Connected to lower-potential side of regulated circuit; forms reference ground return path |
| Cathode | Zener breakdown terminal / voltage regulation output | Marked by band; supplies stable 6.2 V to load when reverse-biased above breakdown threshold |
Key Features
| Feature | Design Value |
|---|---|

Applications
| Overvoltage Protection | Voltage Reference |
|---|---|
Use Scenario: Clamp transient surges on 5 V I/O lines in microcontroller peripherals. IC Role / Device Role: Shunt regulator that conducts excess current when line voltage exceeds 6.2 V. Use Value: Limits voltage excursion to ≤6.6 V (max zener), protecting downstream logic inputs rated for 5.5 V absolute maximum. | Use Scenario: Provide stable bias voltage for op-amp comparators in battery-monitoring circuits. IC Role / Device Role: Precision voltage reference source with low dynamic impedance (10 Ω). Use Value: Maintains <±1% output variation across 10 µA–2 mA load current due to low ZZT and flat TC. |
| Power Supply Feedback | Signal Level Translation |
Use Scenario: Set output voltage in adjustable DC-DC converter feedback divider. IC Role / Device Role: Zener-based reference replacing higher-cost IC references where 1% accuracy suffices. Use Value: Enables cost-effective 3.3 V or 5 V regulation using standard resistor dividers with predictable VZ tolerance (±6.5%). | Use Scenario: Shift 3.3 V logic signals to interface with 5 V legacy peripherals. IC Role / Device Role: Clamp diode limiting high-side swing to 6.2 V while passing low-side transitions. Use Value: Prevents overvoltage damage to 5 V receivers without adding active level-shifting ICs or resistive dividers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5234BS-7-F | Zener voltage 6.2 V, but SOT-323 package (larger footprint, 200 mW PD) and 15 Ω ZZT | Higher thermal resistance (500 °C/W) limits power handling in dense layouts | Select when existing SOT-323 land pattern must be reused and 300 mW rating is not required |
| BZX84-C6V2 | Same 6.2 V rating but SOT-23 package (2.9 mm × 1.3 mm), 350 mW PD, 20 Ω ZZT, no JEDEC qualification | Larger size increases board area; lacks documented high-reliability qualification | Choose for cost-sensitive, non-critical applications where JEDEC compliance is unnecessary |
Compared with MMBZ5234BS-7-F and BZX84-C6V2, BZT52C6V2T-7 delivers superior power density (300 mW in 0.65 mm height), lower dynamic impedance (10 Ω), and JEDEC-qualified reliability-making it optimal for miniaturized, thermally constrained, and mission-critical industrial designs.

FAQ
What is the maximum reverse leakage current for BZT52C6V2T-7 at 4.0 V?
The maximum reverse leakage current is 3.0 µA at VR = 4.0 V and TA = 25°C, as specified in the Electrical Characteristics table. This value remains ≤10 µA up to 85°C ambient, supporting low-power reference designs where standby current must remain below 10 µA.
Is BZT52C6V2T-7 qualified for automotive applications?
No-BZT52C6V2T-7 is not AEC-Q200 qualified. Diodes offers automotive-grade variants with "Q" suffix (e.g., BZT52C6V2TQ-7) that undergo PPAP, are manufactured in IATF 16949 facilities, and meet AEC-Q200 stress testing requirements. Standard BZT52C6V2T-7 is intended for industrial and commercial use only.
What is the thermal resistance from junction to ambient (RθJA) for this device?
RθJA is 417 °C/W when mounted on a FR-4 PCB with single-sided 2 oz. copper and 1.92 mm² pad area. This value assumes natural convection and defines the temperature rise per watt dissipated; actual performance may improve with additional copper pour or thermal vias.
How is polarity identified on the SOD523 package?
Polarity is marked by a cathode band on the top surface of the SOD523 package. The band denotes the cathode terminal; the opposite end is the anode. This marking aligns with industry-standard SOD523 orientation and is visible under 10× magnification during visual inspection or automated optical recognition.
