Product details
Overview
BZT52C6V2-7 from Diodes Incorporated is a surface-mount 6.2 V Zener diode in SOD123 package, rated for 500 mW power dissipation at TL = +75°C and 370 mW at TA = +25°C, with 10 Ω typical zener impedance at 5 mA test current and ±5% voltage tolerance (5.8–6.6 V). It serves as a precision voltage reference or overvoltage clamp in low-power analog signal conditioning and power rail regulation circuits.
For engineers reviewing the BZT52C6V2-7 datasheet, BZT52C6V2-7 pinout, BZT52C6V2-7 application, or BZT52C6V2-7 equivalent, key selection criteria include its 6.2 V nominal zener voltage, 10 Ω dynamic impedance, 4.0 mA maximum reverse current at VR = 3.7 V, temperature coefficient of +0.4 mV/°C, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable voltage across its terminals under varying load or supply conditions. Its planar die construction ensures consistent breakdown characteristics and low leakage, while the SOD123 package supports automated assembly and provides thermal resistance of 338 °C/W (junction-to-ambient) on FR-4 PCB with 1-inch copper pad.
The device exhibits a positive temperature coefficient (+0.4 mV/°C) near 6.2 V, minimizing drift in mid-voltage references. It is specified for operation from –65 °C to +150 °C, with cathode-band polarity marking and matte tin-plated alloy 42 leadframe ensuring solderability per MIL-STD-202.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5234BS-7-F | Same 6.2 V nominal, but SOT-323 package (smaller footprint), 200 mW PD at TA = +25°C, 15 Ω ZZT | Limited thermal mass reduces pulse energy handling; unsuitable for >50 ms transients | Select when board space is constrained and peak power <150 mW; verify thermal derating on thin PCBs |
| BZX84-C6V2 | 6.2 V nominal, SOT-23 package, 300 mW PD, 10 Ω ZZT, but not AEC-Q101 qualified | No automotive qualification; higher moisture sensitivity (Level 1 vs. Level 1, but non-automotive process) | Acceptable for commercial-grade consumer products where AEC-Q101 is not mandated |
Compared with MMBZ5234BS-7-F and BZX84-C6V2, BZT52C6V2-7 offers superior thermal robustness (370 mW vs. 200/300 mW), automotive qualification, and identical zener impedance-making it optimal for industrial and automotive power monitoring where reliability and pulse survivability are critical.

FAQ
What is the maximum reverse voltage (VR) at which IR is guaranteed for BZT52C6V2-7?
The datasheet specifies IR ≤ 3.7 µA at VR = 3.7 V, measured under standard conditions (TA = +25°C). This value reflects the diode's leakage performance well below breakdown and is used to validate stability in high-impedance bias networks. It is not a breakdown threshold but a safe operating limit for reverse-bias applications prior to conduction.
Can BZT52C6V2-7 be used in parallel for higher power dissipation?
No-Zener diodes exhibit negative temperature coefficients at low voltages and positive ones above ~5.6 V, but unit-to-unit VZ variation (±5%) prevents reliable current sharing. Parallel use risks thermal runaway in one device. For higher power, select a single higher-rated Zener or implement active regulation instead.
Is the SOD123 package compatible with standard reflow profiles for lead-free soldering?
Yes-the SOD123 package uses matte tin plating qualified to MIL-STD-202, Method 208, and supports JEDEC J-STD-020D reflow profiles. Peak temperatures up to 260°C are permitted, and moisture sensitivity level 1 eliminates bake requirements before assembly.
Does BZT52C6V2-7 meet automotive qualification requirements beyond AEC-Q101?
BZT52C6V2-7 is qualified to AEC-Q101 only. It does not carry PPAP documentation, IATF 16949 manufacturing certification, or specific automotive grade markings (e.g., "Q" suffix). For full automotive compliance, use the automotive-grade variant BZT52C6V2Q-7-F, which includes additional traceability and lot-level testing.
