Product details
Overview
PD3Z284C36Q-7 from Diodes Incorporated is a 36 V, 0.5 W surface-mount Zener diode in PowerDI323 (Type B) package, rated for 2 mA zener test current, with 60 Ω maximum zener impedance at 1 kHz and ±10% voltage tolerance (34.0–38.0 V). It delivers stable voltage reference and overvoltage protection in automotive power rails and industrial sensor interfaces.
For engineers reviewing the PD3Z284C36Q-7 datasheet, PD3Z284C36Q-7 pinout, PD3Z284C36Q-7 application, or PD3Z284C36Q-7 equivalent, key selection criteria include its AEC-Q101 qualification, 250 °C/W junction-to-ambient thermal resistance, -65 to +150 °C operating temperature range, and 0.5 μA maximum reverse leakage at 25.2 V.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain a stable 36 V reference under regulated current conditions. Its planar die construction ensures consistent voltage regulation and low dynamic impedance across temperature extremes.
The device is optimized for low-power voltage clamping and precision biasing in space-constrained automotive ECUs and industrial control modules. Its PowerDI323 (Type B) package supports high thermal efficiency on standard FR-4 PCBs with recommended pad layout per Diodes' packaging guidelines.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| Zener Voltage (VZ) | 36 V nominal, 34.0–38.0 V range at IZT = 2 mA - defines clamping threshold for overvoltage protection circuits |
| Power Dissipation (PD) | 500 mW - limits continuous energy handling in compact layouts without forced cooling |
| Zener Impedance (ZZT) | 60 Ω max at 1 kHz - determines regulation stability under dynamic load transients |
| Reverse Leakage (IR) | 0.1 μA max at 25.2 V - ensures minimal standby current in battery-powered systems |
| Thermal Resistance (RθJA) | 250 °C/W - sets junction temperature rise under 500 mW dissipation on standard polyimide PCB |
| Operating Temperature | -65 to +150 °C - enables deployment in under-hood automotive and industrial environments |
| AEC-Q101 Qualified | Yes - validates reliability for automotive electronics per stress-test requirements |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C36-7-F | Same 36 V nominal VZ, but SOT-23 package (RθJA = 350 °C/W), 350 mW PD, 90 Ω ZZT | Larger thermal footprint required; less suitable for high-density automotive PCBs | Select when legacy SOT-23 footprint compatibility is mandatory and power dissipation remains ≤300 mW |
| MMSZ5245B-TP | 36 V VZ, SOD-123 package, 500 mW PD, but only AEC-Q200 (not Q101) qualified, 100 Ω ZZT | Not validated for automotive semiconductor stress testing; limited to industrial-grade use | Select for cost-sensitive industrial designs where AEC-Q101 is not required |
Compared with BZX84-C36-7-F and MMSZ5245B-TP, PD3Z284C36Q-7 offers superior thermal performance (250 vs. ≥350 °C/W), tighter impedance (60 Ω), and full AEC-Q101 validation - making it the preferred choice for space-constrained, high-reliability automotive voltage reference nodes.

FAQ
What is the maximum reverse voltage (VR) before significant leakage occurs?
The datasheet specifies 25.2 V as the maximum reverse voltage at which reverse current is guaranteed ≤0.1 μA. At 30.4 V, leakage rises to 0.5 μA, and at 37.4 V (VZ max), it reaches 1.0 μA - confirming sharp knee behavior typical of planar Zener structures.
Can PD3Z284C36Q-7 be used in parallel for higher power handling?
No - Zener diodes exhibit negative temperature coefficient and mismatched VZ tolerances, causing current hogging and thermal runaway when paralleled. For >500 mW applications, use a single higher-rated device or active regulation instead.
Is the PowerDI323 (Type B) package compatible with standard SMT reflow profiles?
Yes - the device is rated for Moisture Sensitivity Level 1 and supports JEDEC J-STD-020-compliant reflow profiles. Its 0.005 g mass and thermally efficient leadframe ensure uniform heating and reliable solder joint formation without special pre-bake steps.
How does temperature affect the 36 V Zener voltage?
The temperature coefficient is +10.4 to +14.0 mV/°C, meaning VZ increases by ~12 mV per °C rise above 25 °C. At +125 °C, VZ shifts up by ~1.2 V - a critical factor in high-temperature voltage reference designs requiring compensation.
