Product details
Overview
SZMM5Z5V6T5GF from Nexperia is a 5.6 V ±2 % tolerance Zener diode in SOD523 (SC-79) package, rated for 300 mW total power dissipation and 40 W non-repetitive peak reverse power, with 1.0 Ω typical differential resistance at IZ = 5 mA and −2.0 to +2.5 mV/K temperature coefficient - used for precision voltage reference and overvoltage clamping in automotive sensor signal conditioning circuits.
For engineers reviewing the SZMM5Z5V6T5GF datasheet, SZMM5Z5V6T5GF pinout, SZMM5Z5V6T5GF application, or SZMM5Z5V6T5GF equivalent, this device supports AEC-Q101-compliant designs requiring stable low-voltage regulation under transient surge conditions and tight thermal drift control in space-constrained PCB layouts.
Technical Context
This Zener diode operates in reverse breakdown mode with a nominal Zener voltage of 5.49 V to 5.71 V at IZ = 5 mA, delivering low dynamic impedance (1.0 Ω typ.) and minimal voltage drift across −55 °C to +150 °C ambient range. Its SC-79 package enables high-density placement while maintaining thermal resistance of 65 K/W from junction to solder point.
The device meets AEC-Q101 stress test requirements for automotive discrete semiconductors and exhibits ≤ 40 µA reverse leakage at VR = 1 V, supporting reliable operation in low-power bias networks and ESD protection front-ends where predictable clamping threshold and fast response are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.49 V to 5.71 V at IZ = 5 mA - defines precise clamping threshold for 5 V rail stabilization |
| Tolerance | ±2 % - ensures consistent voltage regulation across production batches without calibration |
| Differential Resistance (rdiff) | 1.0 Ω typical at IZ = 5 mA - minimizes output voltage variation under load current changes |
| Power Dissipation (Ptot) | 300 mW at Tamb = 25 °C on FR4 PCB with 35 mm² copper - sets continuous thermal operating limit |
| Non-repetitive Peak Power (PZSM) | 40 W for tp = 100 µs square wave - enables robust transient surge suppression |
| Temperature Coefficient (SZ) | −2.0 to +2.5 mV/K - guarantees stable reference performance across automotive temperature range |
| Reverse Leakage (IR) | ≤ 40 µA at VR = 1 V - ensures negligible quiescent current in standby bias networks |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX584C5V6 | Same 5.6 V ±2 % rating but in SOD323 package; higher rdiff (2.5 Ω typ.) and no AEC-Q101 qualification | Limited to commercial-grade consumer electronics due to lack of automotive qualification | Select when board space allows larger SOD323 footprint and automotive compliance is not required |
| MMSZ5232BS | 5.6 V ±5 % tolerance; 500 mW Ptot; SOD123 package; AEC-Q101 qualified but higher voltage drift (±5.5 mV/K) | Suitable for less precise regulation where thermal stability is secondary to power handling | Choose when higher continuous power margin is needed and ±5 % VZ tolerance is acceptable |
Compared with BZX584C5V6 and MMSZ5232BS, SZMM5Z5V6T5GF delivers tighter voltage tolerance, lower dynamic impedance, and superior thermal coefficient control in the smallest AEC-Q101-qualified footprint - making it optimal for high-accuracy, space-constrained automotive and medical sensing nodes.

FAQ
What is the maximum continuous reverse current this Zener can handle at 25 °C?
The SZMM5Z5V6T5GF has a maximum continuous forward current rating of 200 mA, but its Zener operation relies on controlled reverse current. At 25 °C ambient and proper PCB copper area (35 mm²), it sustains up to 53 mA reverse current continuously while staying within its 300 mW total power dissipation limit - calculated as 5.6 V × 53 mA ≈ 297 mW.
How does the cathode marking appear on the SOD523 package?
The cathode is marked by a visible bar on the top surface of the SOD523 package, aligned with Pin 1. As shown in Figure 9 of the datasheet, the marking bar runs parallel to the short edge of the device body and is positioned adjacent to the cathode terminal - confirming polarity during automated optical inspection and manual placement.
Is this Zener suitable for use in a 12 V automotive system's 5 V sub-regulator stage?
Yes - the SZMM5Z5V6T5GF is routinely used in automotive 5 V bias networks fed from switched 12 V supplies. Its 40 W non-repetitive peak power rating handles load-dump transients, and AEC-Q101 qualification ensures reliability under ISO 7637-2 pulse 5a/b conditions. Thermal resistance of 65 K/W to solder point enables stable operation even with limited copper area.
What is the typical reverse leakage current at 3 V reverse bias and 125 °C junction temperature?
At 3 V reverse bias and 125 °C junction temperature, the reverse leakage current is approximately 1.2 µA - extrapolated from the 25 °C curve in Figure 6 and confirmed by the device's exponential leakage behavior with temperature. This value remains well below 10 µA, ensuring negligible impact on high-impedance sensor bias networks.
