Product details
Overview
BZT52C6V2LP-7 from Diodes Incorporated is a surface-mount Zener diode with nominal zener voltage 6.2 V, ±5% tolerance (5.8–6.6 V), 250 mW power dissipation, and low dynamic impedance of 10 Ω at 5 mA test current - used for precision voltage regulation and overvoltage protection in compact DC power rails.
For engineers reviewing the BZT52C6V2LP-7 datasheet, BZT52C6V2LP-7 pinout, BZT52C6V2LP-7 application, or BZT52C6V2LP-7 equivalent, this device serves as a stable, AEC-Q101-qualified voltage reference in automotive body electronics, industrial sensor interfaces, and portable battery-powered systems where space-constrained DFN1006-2 packaging and low leakage (<3 µA @ 4.0 V) are critical.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain a stable reference voltage across its terminals under varying load and temperature conditions. Its 10 Ω zener impedance at 5 mA ensures minimal voltage deviation during transient current changes, and its −2.0 to +0.4 mV/°C temperature coefficient enables predictable drift behavior in ambient ranges from −65 °C to +150 °C.
The device uses a NiPdAu-plated copper leadframe and green molding compound compliant with UL 94V-0, supporting reflow soldering per J-STD-020C Level 1 moisture sensitivity. Cathode identification is marked by a dot on the top surface of the DFN1006-2 package.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.2 V nominal, 5.8–6.6 V range at 5 mA - defines regulated output voltage under standard bias |
| Power Dissipation (PD) | 250 mW at TA = 25 °C - sets maximum continuous power handling on FR-4 PCB with recommended pad layout |
| Zener Impedance (ZZT) | 10 Ω at IZT = 5 mA - determines voltage stability against load current variation |
| Reverse Leakage (IR) | 3.0 µA max at VR = 4.0 V - limits standby current in low-power voltage clamp circuits |
| Temp. Coefficient (αVZ) | −2.0 to +0.4 mV/°C at IZTC = 5 mA - quantifies voltage drift over operating temperature range |
| Forward Voltage (VF) | 0.9 V at IF = 10 mA - relevant for polarity-check or dual-function rectifier/Zener applications |
| Package | DFN1006-2 (1.0 × 0.6 × 0.5 mm) - ultra-small footprint enabling high-density PCB layouts |
Pinout & Package
DFN1006-2 package: 2-terminal surface-mount device with exposed cathode terminal (marked by dot) and anode terminal. No internal die bonding wire; terminals are formed from single copper leadframe.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (Dot-marked side) | Reverse-biased Zener terminal | Connected to higher-potential node in regulation/clamp configuration; defines polarity for breakdown conduction |
| Anode | Reference/ground terminal | Typically tied to system ground or lower-voltage rail; completes reverse-bias path for Zener operation |
Key Features

| Green molding compound | UL 94V-0 rated flame-retardant plastic enabling safer operation in enclosed environments |
| Level 1 moisture sensitivity | Unlimited floor life at ≤30 °C/60% RH - eliminates bake requirement prior to reflow assembly |
| NiPdAu terminal finish | Solderable per MIL-STD-202 Method 208; supports consistent wetting and joint integrity in automated SMT lines |
Applications
| Automotive Body Control Module | Industrial Sensor Signal Conditioning |
|---|---|
Use Scenario: Voltage clamping of LIN bus transceiver I/O pins against load dump transients up to 40 V. IC Role / Device Role / Timing Role: Zener diode acting as shunt overvoltage protector in parallel with transceiver input. Use Value: Limits peak voltage to 6.6 V (max VZ) while drawing <100 µA leakage at 5 V - avoids false triggering without loading signal line. |
Use Scenario: Providing stable 6.2 V reference for 12-bit ADC in 4–20 mA loop-powered pressure transmitter. IC Role / Device Role / Timing Role: Precision voltage reference source for ADC VREF input via resistor divider and buffer. Use Value: Delivers <±0.5% initial accuracy and <50 ppm/°C effective TC when biased at 5 mA - improves end-point calibration stability. |

Use Scenario: Regulating 6.2 V supply for analog front-end op-amps driving photodiode current-to-voltage conversion. IC Role / Device Role / Timing Role: Low-noise shunt regulator maintaining constant bias for transimpedance amplifier. Use Value: 10 Ω ZZT minimizes ripple-induced gain error; 0.001 g mass enables weight-sensitive wearable design. |
Use Scenario: Clamping 3.3 V LDO output against ESD events on battery-charging circuitry in battery-operated detector. IC Role / Device Role / Timing Role: Secondary overvoltage clamp protecting LDO feedback node during fast-rising transients. Use Value: Activates at 6.6 V (well above 3.3 V rail) with <3 µA leakage at 4 V - preserves battery life over 10-year deployment. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5234BS-7-F | Zener voltage 6.0 V (±5%), 200 mW PD, SOD-523 package (1.3 × 0.8 mm) | Larger footprint; higher thermal resistance (RθJA = 625 °C/W) reduces power margin at elevated ambient | Select when legacy SOD-523 board space is fixed and 0.2 V lower VZ is acceptable |
| PDZ6.2B,115 | Zener voltage 6.2 V (±5%), 250 mW PD, SOD-323 package (1.7 × 1.3 mm) | 2× larger area than DFN1006-2; 100 Ω ZZT at 5 mA degrades regulation accuracy under dynamic load | Choose only if existing SOD-323 footprint must be retained and tighter impedance is not required |
Compared with MMBZ5234BS-7-F and PDZ6.2B,115, BZT52C6V2LP-7 offers superior regulation precision (10 Ω vs ≥100 Ω ZZT), smallest PCB footprint (1.0 × 0.6 mm), and AEC-Q101 qualification - making it optimal for new automotive and space-constrained industrial designs requiring tight voltage control.

FAQ
What is the maximum reverse voltage this Zener can safely clamp without damage?
The absolute maximum reverse voltage is defined by its 250 mW power rating and thermal resistance. At 25 °C ambient with recommended PCB layout, sustained clamping above 6.6 V requires current limiting to keep power below 250 mW - e.g., 37.9 mA at 6.6 V. Exceeding this causes junction overheating and parametric shift.
Is the cathode marking visible after reflow soldering?
Yes. The cathode dot is laser-marked on the molded plastic surface and remains clearly visible post-reflow. It is located on the same side as the device top surface and aligns with the cathode terminal edge of the DFN1006-2 package - verified under 20× magnification per Diodes Inc. AP02007 packaging standard.
Does this Zener meet automotive PPAP requirements?
Yes. As an AEC-Q101-qualified part, BZT52C6V2LP-7 has completed stress testing including HTGB, AC/DC life test, temperature cycling, and ESD (HBM ≥2 kV). Full PPAP documentation - including material certifications, process flow, and test reports - is available upon request for qualified automotive customers.
Can this device replace a through-hole 1N4735A in an existing design?
No direct replacement: 1N4735A is a 6.2 V, 1 W through-hole Zener in DO-41 package. BZT52C6V2LP-7 has identical VZ but only 250 mW rating and DFN1006-2 footprint. Substitution requires verifying power dissipation margins and redesigning PCB pads - it is suitable only where space and power constraints align.
