Product details
Overview
SMAZ5V6-13 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 uses an SMA package, features a cathode band polarity marker, and is RoHS-compliant and halogen-free for automotive and industrial power regulation.
For engineers reviewing the SMAZ5V6-13 datasheet, SMAZ5V6-13 pinout, SMAZ5V6-13 application, or SMAZ5V6-13 equivalent, key selection criteria include zener voltage accuracy, thermal resistance (RθJA = 100 °C/W), power derating above +50°C, and compatibility with automated SMT assembly on FR-4 PCBs.
Technical Context
This Zener diode operates in reverse breakdown to provide stable voltage reference or overvoltage clamping. Its 1.0 W power rating enables use in moderate-power regulation circuits, while its 30 °C/W junction-to-terminal thermal resistance supports reliable heat transfer when mounted per Diodes Inc.'s recommended pad layout.
The device exhibits 250 Ω dynamic impedance at 2.0 mA test current and maintains low leakage (≤2.0 µA at 5.0 V), ensuring precision in low-current biasing and sensing applications where stability under varying temperature and load is critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.60 V nominal, 5.32–5.88 V range - defines precise clamping/reference level at 2.0 mA |
| Power Dissipation (PD) | 1.0 W @ TA = +25°C - sets maximum continuous power handling before thermal shutdown |
| Zener Impedance (ZZT) | 250 Ω max @ IZT = 2.0 mA - determines voltage regulation stiffness under load variation |
| Reverse Leakage (IR) | 2.0 µA max @ VR = 5.0 V - ensures minimal quiescent current in standby or high-impedance bias networks |
| Thermal Resistance (RθJA) | 100 °C/W - quantifies junction-to-ambient temperature rise per watt, guiding heatsinking and layout decisions |
| Package | SMA (DO-214AC) - standardized surface-mount outline with 4.00–4.60 mm body width and 2.29–2.92 mm height |
Pinout & Package
The SMA package is a 2-terminal surface-mount case with molded plastic body (UL 94V-0), cathode identified by a visible band. Terminals are matte tin-plated for solderability per MIL-STD-202, Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal / Zener cathode reference node | Connected to lower-potential side in clamping configuration; forms reference ground return path |
| Cathode | Zener breakdown terminal / voltage regulation node | Connected to regulated rail or protection point; carries full zener current during overvoltage events |
Key Features
| Feature | Design Value |
|---|---|
| 1.0 W Power Rating | Enables robust voltage clamping in 5–12 V supply rails without external heatsinking on standard FR-4 |
| ±5% Zener Voltage Tolerance | Supports tight regulation in feedback loops for DC-DC converters and LDO references |
| Lead-Free & Halogen-Free Construction | Meets IPC-J-STD-020 Level 1 moisture sensitivity and automotive AEC-Q200 environmental stress requirements |
| Automated Assembly Compatibility | SMA footprint aligns with industry-standard pick-and-place and reflow profiles (J-STD-020 compliant) |
Applications
| Power Supply Overvoltage Protection | Low-Power Voltage Reference |
|---|---|
Use Scenario: Clamping transient surges on 5 V microcontroller I/O lines or USB VBUS inputs. IC Role / Device Role / Timing Role: Zener acts as shunt regulator, diverting excess current to ground when input exceeds 5.6 V. Use Value: Prevents latch-up or damage to downstream logic with ≤2.0 µA leakage at 5.0 V and fast response to ESD-like transients. | Use Scenario: Providing stable bias voltage for op-amp comparators or ADC reference dividers in battery-powered sensors. IC Role / Device Role / Timing Role: Functions as precision voltage source with 5.60 V ±5% output and low dynamic impedance (250 Ω). Use Value: Delivers consistent reference across temperature (−65°C to +150°C) without active circuitry or trimming. |
| Automotive Body Control Module (BCM) Input Conditioning | Industrial PLC Analog Input Protection |
Use Scenario: Protecting LIN bus interface pins against load-dump spikes up to 40 V in 12 V vehicle systems. IC Role / Device Role / Timing Role: Shunt clamp activated only during overvoltage events; remains high-impedance during normal operation. Use Value: Survives 1.0 W pulse energy per ISO 7637-2 Pulse 5a, leveraging 100 °C/W RθJA and FR-4 thermal design. | Use Scenario: Guarding 4–20 mA current loop receivers against field-wiring faults or induced surges. IC Role / Device Role / Timing Role: Limits input voltage to safe levels for precision instrumentation amplifiers and isolators. Use Value: Maintains signal integrity with <2.0 µA leakage at rated voltage, avoiding offset errors in µA-level analog paths. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C5V6 (Diodes Inc.) | 0.3 W rating, SOT-23 package, same 5.6 V ±5% VZ, higher ZZT (60 Ω min) | Lower power handling limits use to signal-level clamping only | Select for space-constrained PCBs where 1.0 W dissipation is unnecessary |
| 1N4734A (ON Semiconductor) | 1.0 W DO-41 through-hole package, 5.6 V ±5%, ZZT = 5 Ω @ 45 mA | Requires manual insertion or wave soldering; unsuitable for fully automated SMT lines | Select when legacy through-hole assembly or higher current regulation (>20 mA) is required |
Compared with BZX84-C5V6 and 1N4734A, SMAZ5V6-13 uniquely balances SMT manufacturability, 1.0 W capability, and low-leakage performance in a compact SMA outline-making it optimal for modern automotive and industrial control modules requiring both reliability and process compatibility.

FAQ
What is the maximum allowable ambient temperature for continuous 1.0 W operation?
The SMAZ5V6-13 is rated for 1.0 W dissipation only at TA = +25°C. Above +50°C, power must be linearly derated at 10 mW/°C, limiting usable power to 0.5 W at +100°C. This derating is based on thermal resistance measurements using Diodes Inc.'s standard FR-4 test board layout.
Does SMAZ5V6-13 have a specified capacitance value for high-frequency filtering?
No capacitance specification is provided in the DS18015 datasheet. Figure 2 shows typical total capacitance vs. reverse voltage for related devices (e.g., SMAZ5V6 ≈ 100–150 pF at 0 V), but Diodes Inc. does not guarantee or characterize CT for this part. For RF decoupling, a dedicated capacitor should be used in parallel.
Can SMAZ5V6-13 replace SMAZ5V1 in existing designs?
Yes, if the design accommodates the higher zener voltage (5.60 V vs. 5.10 V) and reduced test current (2.0 mA vs. 100 mA). SMAZ5V1 has lower ZZT (5.0 Ω) and higher IZM (196 mA), so substitution may affect regulation accuracy and surge handling-verify under worst-case load and temperature conditions.
Is the SMAZ5V6-13 qualified to AEC-Q200 for automotive use?
While the SMAZ5V6-13 meets RoHS, halogen-free, and J-STD-020 moisture sensitivity requirements, Diodes Inc. does not list it as AEC-Q200-qualified in DS18015 or official product briefs. For automotive safety-critical applications, consult Diodes Inc.'s AEC-Q200-certified Zener portfolio (e.g., BZT52-B5V6) instead.
