The SOD-923 package fits on dense PCBs. ## Key ratings that drive the BOM decision Reverse standoff voltage is 5 V max — the diode stays off below that, so it won't leak on a 5 V rail. Breakdown voltage starts at 5.8 V, meaning it begins conducting just above the normal operating level. Clamping voltage is 9.8 V at 1 A peak pulse current (8/20 µs waveform) — that's the ceiling the protected IC sees during an ESD event. Lower clamping means less stress on the downstream silicon. Capacitance is 1.3 pF at 1 MHz — low enough for high-speed interfaces like USB 2.0, CAN, or LVDS without rounding off the signal edges. If you're protecting a 100BASE-T1 or 1000BASE-T Ethernet PHY, that capacitance is well within the link budget. Operating temperature range spans -55°C to 150°C — the 150°C upper limit covers under-hood automotive and industrial enclosures near motors or power stages. The SOD-923 package is widely sourced across multiple distributors; we can quote to your BOM quantity against current market pricing.","metaTitle":"ESD9P5.0ST5G Zener ESD Protector – onsemi, SOD-923, AEC-Q101","metaDescription":"onsemi ESD9P5.0ST5G Zener ESD protection diode, 5 V reverse standoff, 1.3 pF capacitance, AEC-Q101 qualified, SOD-923 package.
