Product details
Overview
SZNZ8F7V5MX2WT5G from onsemi is an AEC-Q101-qualified Zener diode designed for precision voltage regulation and overvoltage protection in space-constrained automotive and portable electronics. It delivers a nominal Zener voltage of 7.5 V (min 7.13 V, max 7.88 V) at 5 mA test current, with dynamic impedance ≤30 Ω, reverse leakage ≤0.5 µA at 4 V, and capacitance of 100 pF at 0 V bias - enabling stable clamping in low-power ESD-sensitive signal paths.
For engineers reviewing the SZNZ8F7V5MX2WT5G datasheet, pinout, applications, or equivalent options, key selection criteria include its wettable flank X2DFNW2 package for AOI compatibility, ±3.5% voltage tolerance, 250 mW power rating on FR-4 (1 oz Cu, minimum pad), and automotive-grade qualification supporting under-hood and ADAS subsystems.
Technical Context
This device operates as a unidirectional, silicon planar Zener diode optimized for low-voltage regulation and transient suppression in DC bias networks. Its breakdown behavior is characterized by a well-defined knee at IZT = 5 mA, with temperature coefficient of ±4 mV/°C across −55 °C to +150 °C and thermal resistance RJA = 415 °C/W on standard FR-4 board.
The X2DFNW2 package integrates cathode/anode terminals on opposing edges with wettable flanks, enabling reliable solder joint inspection. Electrical performance is specified under strict AEC-Q101 stress conditions including HTGB, TCT, and H3TRB - confirming suitability for automotive control units requiring long-term parametric stability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 7.13 V to 7.88 V @ IZT = 5 mA - defines clamping threshold for 7.5 V rail protection |
| Power Dissipation (PD) | 250 mW @ TA = 25 °C (FR-4, 1 oz Cu, min pad) - sets maximum continuous DC power handling |
| Zener Impedance (ZZT) | ≤30 Ω @ IZT = 5 mA - ensures minimal voltage shift under load variation |
| Reverse Leakage (IR) | ≤0.5 µA @ VR = 4 V - guarantees low standby current in always-on circuits |
| Capacitance (C) | 100 pF @ VR = 0 V, f = 1 MHz - limits high-frequency signal loading in data lines |
| Forward Voltage (VF) | ≤0.9 V @ IF = 10 mA - supports bidirectional ESD clamp configurations |
| Junction Temp Range | −65 °C to +150 °C - enables operation in engine bay and powertrain environments |

FAQ
What is the Zener voltage tolerance of SZNZ8F7V5MX2WT5G?
The SZNZ8F7V5MX2WT5G has a nominal Zener voltage of 7.5 V with a tolerance of ±3.5%, specified as 7.13 V minimum and 7.88 V maximum at IZT = 5 mA. This standard tolerance series is distinct from the tight-tolerance SZNZ8F7V5SMX2WT5G variant, which offers ±2% (7.33–7.67 V). Both share identical packaging and AEC-Q101 qualification.
Is SZNZ8F7V5MX2WT5G suitable for automotive applications?
Yes, SZNZ8F7V5MX2WT5G is explicitly AEC-Q101 qualified and PPAP capable, with the "SZ" prefix indicating compliance for automotive and other applications requiring unique site and control change requirements. It passes HTGB, TCT, and H3TRB stress tests, making it appropriate for engine control units, body electronics, and ADAS subsystems.
What package type does SZNZ8F7V5MX2WT5G use?
SZNZ8F7V5MX2WT5G uses the X2DFNW2 surface-mount package (Case 711BG), measuring 1.00 mm × 0.60 mm × 0.37 mm with 0.65 mm pitch. Its wettable flank design enables full automated optical inspection (AOI) of solder joints, and the low 0.40 mm body height supports ultra-thin PCB assemblies in portable and automotive modules.
What is the maximum power dissipation for SZNZ8F7V5MX2WT5G?
SZNZ8F7V5MX2WT5G has a maximum power dissipation of 250 mW at TA = 25 °C on FR-4 board with 1 oz copper and minimum pad layout. Derating is 1.5 mW/°C above 25 °C. For enhanced thermal performance, a 150 mm² copper area raises PD to 500 mW with 1.2 mW/°C derating - verified per Note 2 in the datasheet.
How does the capacitance of SZNZ8F7V5MX2WT5G affect high-speed signal lines?
SZNZ8F7V5MX2WT5G exhibits 100 pF capacitance at 0 V bias and 1 MHz, measured per Figure 7. This value remains stable below 10 MHz, making it suitable for clamping USB Type-C CC lines and LIN bus signals without degrading edge rates. At higher frequencies (>100 MHz), parasitic effects dominate, so it is not recommended for RF or high-speed serial data path protection.
