Product details
Overview
SMAZ10-13-F from Diodes Incorporated is a 1.0W surface-mount Zener diode with nominal zener voltage of 10.0V (±5%), 9.5V–10.5V range, 4.0mA test current, and 200Ω maximum zener impedance at IZT; designed for voltage regulation and overvoltage protection in DC power rails and reference circuits.
For engineers reviewing the SMAZ10-13-F datasheet, SMAZ10-13-F pinout, SMAZ10-13-F application, or SMAZ10-13-F equivalent, key selection criteria include zener voltage tolerance, power derating above +50°C, thermal resistance (RθJA = 100°C/W), reverse leakage at VR = 7.6V, and SMA package compatibility with automated SMT assembly.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable voltage across its terminals under varying load or input conditions. It uses silicon PN-junction technology with cathode band polarity marking and is rated for continuous operation from –65°C to +150°C.
Its 1.0W power dissipation is thermally limited by junction-to-ambient resistance (100°C/W) and requires derating at 10mW/°C above +50°C on FR-4 PCB per specified pad layout. Zener impedance is measured at 4.0mA test current and reflects regulation stiffness under small-signal dynamic conditions.
Key Specifications

| Zener Voltage Range | 9.5 V to 10.5 V - ±5% tolerance ensures predictable clamping in production |
| Power Dissipation | 1.0 W - supports moderate-power regulation without heatsinking on standard PCB |
| Zener Impedance | 200 Ω max @ 4.0 mA - defines voltage deviation under load transients |
| Reverse Leakage | 1.0 µA @ 7.6 V - low standby current preserves efficiency in battery-backed systems |
| Thermal Resistance JA | 100 °C/W - determines temperature rise under full load on typical FR-4 layout |
| Operating Temp | –65°C to +150°C - suitable for industrial and automotive under-hood environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C10LT1G | 300mW rating, SOT-23 package, 10V ±5%, 150Ω Zz @ 5mA | Lower power handling; suited for signal-level references, not rail clamping | Select when board space is constrained and power <300mW |

Compared with BZX84-C10LT1G and 1N4740A, SMAZ10-13-F uniquely balances 1.0W SMT capability, industry-standard SMA footprint, and tight thermal resistance-making it optimal for automated production of compact, thermally robust voltage regulation nodes.

FAQ
What is the maximum reverse voltage (VR) at which IR is guaranteed for SMAZ10-13-F?
The datasheet specifies 1.0 µA maximum reverse leakage current at VR = 7.6 V. This value is measured at TA = +25°C and defines the upper bound of off-state conduction before reaching the nominal 10.0V zener knee. It ensures minimal quiescent power loss in always-on reference circuits.
How does thermal derating apply to SMAZ10-13-F in real-world PCB layouts?
SMAZ10-13-F must be derated at 10 mW/°C above +50°C ambient when mounted on a standard FR-4 PCB (1" × 0.85") with Diodes' recommended pad layout. At +70°C ambient, usable power drops to 0.8W; at +100°C, it falls to 0.5W-requiring layout review if sustained high-temperature operation is needed.
Is SMAZ10-13-F suitable for ESD protection in USB or HDMI interfaces?
No. While it provides basic overvoltage clamping, SMAZ10-13-F lacks the sub-nanosecond response time, low clamping voltage (VCL), and high peak pulse power (e.g., 300W+) required for IEC 61000-4-2 Level 4 ESD protection. Dedicated TVS diodes like D3V3M1U2SOT-23 are appropriate for such interfaces.
Does the SMAZ10-13-F have a defined capacitance value relevant for high-frequency filtering?
Capacitance is not characterized in the datasheet for SMAZ10-13-F. Figure 2 shows typical total capacitance vs. reverse voltage for related parts (e.g., SMAZ12 ≈ 15 pF at 0 V), but no value is specified for SMAZ10. For decoupling or RF filtering, a dedicated ceramic capacitor should be used in parallel-not reliance on diode junction capacitance.
