Product details
Overview
SMAZ5V6-13-F from Diodes Incorporated is a 1.0W surface-mount Zener diode with a nominal zener voltage of 5.60 V (±5% tolerance), 2.0 mA test current, 250 Ω maximum zener impedance at IZT, and 2.0 µA maximum reverse leakage at 5.0 V. It is used for precision voltage regulation and overvoltage protection in DC power rails of industrial control modules and embedded sensor interfaces.
For engineers reviewing the SMAZ5V6-13-F datasheet, SMAZ5V6-13-F pinout, SMAZ5V6-13-F application, or SMAZ5V6-13-F equivalent, key selection criteria include zener voltage accuracy, thermal resistance (RθJA = 100 °C/W), power derating above +50°C, and SMA package compatibility with automated SMT assembly.
Technical Context
This device operates as a two-terminal voltage reference diode, conducting in reverse breakdown to clamp voltage across load circuits. Its 5.60 V nominal zener voltage is specified at IZT = 2.0 mA, with dynamic impedance of 250 Ω measured under the same condition.
Thermal performance is defined for mounting on FR-4 PCB (1" × 0.85", 0.062" thick) per Diodes Inc. pad layout. Power dissipation is rated at 1.0 W up to +50°C, derating linearly at 10 mW/°C above that temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.60 V nominal, 5.32–5.88 V range at 2.0 mA - defines clamping threshold for 5 V rail protection |
| Power Dissipation (PD) | 1.0 W at TA ≤ +50°C - supports continuous regulation in compact industrial PCB layouts |
| Zener Impedance (ZZT) | 250 Ω max at IZT = 2.0 mA - limits output voltage variation under load transients |
| Reverse Leakage (IR) | 2.0 µA max at VR = 5.0 V - ensures minimal quiescent current in always-on monitoring circuits |
| Thermal Resistance (RθJA) | 100 °C/W - determines junction temperature rise under 1 W load on standard FR-4 board |
| Package | SMA (DO-214AC) - industry-standard SMT footprint compatible with IPC-7351B land patterns |
Pinout & Package
The SMA package is a 2-terminal surface-mount case with cathode identified by a band or notch. Terminals are matte tin-plated for solderability per MIL-STD-202, Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal / low-side reference node | Connected to circuit ground or lower-potential rail during zener operation |
| Cathode | Reverse-biased breakdown terminal / regulated output node | Connected to protected node; clamps voltage to ~5.6 V when reverse voltage exceeds threshold |
Key Features
| Feature | Design Value |
|---|---|
| 1.0 W power rating | Enables robust transient suppression without external heatsinking in space-constrained designs |
| ±5% zener voltage tolerance | Supports cost-sensitive applications where tight regulation is not required (e.g., brown-out detection) |
| Lead-free, RoHS-compliant finish | Meets global environmental compliance requirements for industrial and consumer electronics |
| Moisture Sensitivity Level 1 | Eliminates bake requirements prior to reflow, reducing manufacturing overhead |

Equivalent & Alternatives
The following parts are listed as comparable options for similar zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C5V6 | 300 mW rating, SOT-23 package, 5.6 V ±5%, ZZT = 40 Ω @ 5 mA | Lower power handling; suited for signal-level clamping, not rail regulation | Select for low-current bias networks where thermal margin is sufficient |
| 1N5232B | 500 mW rating, DO-35 axial lead, 5.6 V ±5%, ZZT = 17 Ω @ 20 mA | Through-hole only; higher test current yields lower dynamic impedance but requires manual assembly | Select for prototyping or legacy through-hole designs requiring tighter regulation at higher current |
Compared with BZX84-C5V6 and 1N5232B, SMAZ5V6-13-F provides 1.0 W power handling in an SMT-compatible SMA package, making it optimal for automated production of industrial power-rail protection where thermal robustness and board-space efficiency are critical.

FAQ
What is the maximum allowable reverse voltage before breakdown for SMAZ5V6-13-F?
The nominal zener voltage is 5.60 V with a tolerance of ±5%, meaning breakdown occurs between 5.32 V and 5.88 V at the specified test current of 2.0 mA. Below 5.32 V, reverse leakage remains ≤2.0 µA at 5.0 V, confirming non-conductive behavior in normal operation.
Can SMAZ5V6-13-F be used in parallel for higher power dissipation?
No - Zener diodes exhibit negative temperature coefficients and mismatched characteristics, causing current hogging when paralleled. For >1.0 W applications, use a single higher-power device (e.g., 1.5 W SMAJ series) or active regulation instead of parallel Zeners.
Is the SMAZ5V6-13-F suitable for automotive applications?
Yes - its operating temperature range (−65°C to +150°C), RoHS compliance, and halogen/antimony-free "Green" construction meet baseline automotive qualification requirements. However, AEC-Q200 stress testing is not claimed; system-level validation is required for safety-critical functions.
How does the 100 °C/W RθJA value translate to real-world thermal performance?
At 1.0 W dissipation on a standard FR-4 board (1" × 0.85"), junction temperature rises 100°C above ambient. So at TA = +50°C, TJ = +150°C - the absolute maximum. Derating to 0.5 W at +100°C ambient keeps TJ within safe limits.
