Product details
Overview
DDZX5V6B-13 from Diodes Incorporated is a surface-mount precision Zener diode with nominal zener voltage 5.6 V (min 5.45 V, max 5.73 V), 300 mW power dissipation on FR-4 PCB, 11 Ω zener impedance at 20 mA test current, and 0.5 μA reverse leakage at 2.5 V. It serves as a stable voltage reference in low-power analog circuits and regulator feedback paths.
For engineers reviewing the DDZX5V6B-13 datasheet, DDZX5V6B-13 pinout, DDZX5V6B-13 application, or DDZX5V6B-13 equivalent, this part is selected for tight-tolerance voltage regulation in automotive-compliant designs, industrial sensor signal conditioning, and space-constrained power management where AEC-Q101 reliability and SOT23 footprint are required.
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 sharp knee characteristic and low dynamic impedance (11 Ω at IZT = 20 mA) ensure minimal voltage deviation during transient current changes.
The device exhibits a typical temperature coefficient near zero for 5.6 V rating (inferred from Fig. 16 trend for DDZX6V2B–DDZX10C), enabling stable performance over –65°C to +150°C operating range. Its SOT23 package supports automated assembly and delivers thermal resistance of 417°C/W on FR-4 board.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.45–5.73 V at IZT = 20 mA - ensures ±2.2% tolerance for precision reference applications |
| Zener Impedance (ZZT) | 11 Ω at IZT = 20 mA - minimizes output voltage variation under load current shifts |
| Power Dissipation (PD) | 300 mW on FR-4 PCB - defines maximum continuous power handling without derating below 25°C |
| Reverse Leakage (IR) | 0.5 μA at VR = 2.5 V - guarantees negligible error current in high-impedance reference nodes |
| Thermal Resistance (RθJA) | 417°C/W - determines junction-to-ambient temperature rise per watt dissipated on standard layout |
| Operating Temperature | –65°C to +150°C - supports deployment in under-hood automotive and industrial environments |

FAQ
What is the maximum continuous Zener current for DDZX5V6B-13 at 25°C?
The device is rated for 300 mW power dissipation at 25°C ambient. At nominal 5.6 V, this corresponds to a maximum continuous Zener current of approximately 53.6 mA (300 mW ÷ 5.6 V). Derating begins above 25°C per Fig. 1, reaching zero at 150°C.
Is DDZX5V6B-13 pin-compatible with other SOT23 Zener diodes?
Yes-it uses standard SOT23 pinout: Pin 1 = Anode, Pin 2 = Cathode, Pin 3 = NC. This matches industry-standard SOT23 Zener orientation used by Diodes Inc., ON Semiconductor, and Vishay, enabling drop-in replacement where electrical specs align.
Does DDZX5V6B-13 require external heat sinking in typical PCB layouts?
No. With RθJA = 417°C/W on FR-4 and 300 mW rating, junction temperature rise is ~125°C at full power-within safe limits for short pulses. For continuous 300 mW operation, board-level copper pour or thermal vias are recommended but not mandatory per datasheet layout guidelines.
Can DDZX5V6B-13 be used in place of a 5.1 V Zener like DDZX5V1B?
No-DDZX5V6B-13 has a distinct 5.45–5.73 V zener range versus DDZX5V1B's 4.94–5.20 V range. Substituting would shift reference voltage by >5%, violating most analog circuit tolerances. Use only when the design explicitly targets 5.6 V regulation.
