SZMMSZ5237BT1GSZMMSZ5237BT1G Overview
The SZMMSZ5237BT1G from onsemi is an automotive-grade 8.2 V, 500 mW, ±5% single Zener diode in a surface-mount SOD-123 package, supplied on tape and reel. It is the AEC-Q101 automotive-qualified variant of the industry-standard MMSZ5237B (JEDEC 1N5237B) and is used as a voltage regulator, voltage reference and overvoltage clamp. The "SZ" prefix marks onsemi's automotive/high-reliability grade, "T1" is tape-and-reel and "G" is Pb-free / halogen-free.

Equivalents & Related Parts
Electrically identical to the plain MMSZ5237BT1G but with AEC-Q101 automotive qualification and stricter site/change control - choose the SZ version for automotive BOMs. The through-hole equivalent is the axial 1N5237B (DO-35). Within the MMSZ52xxB 500 mW SOD-123 series the neighbours are the MMSZ5236B (7.5 V) and MMSZ5238B (8.7 V). Browse more onsemi Zener diodes at GlobX.

FAQs
Frequently Asked Questions about SZMMSZ5237BT1Gby ON SEMICON
What is the Zener voltage of the SZMMSZ5237BT1G?
The SZMMSZ5237BT1G has a nominal Zener voltage of 8.2 V (+/-5% tolerance), measured at a test current (Izt) of 20 mA. It is rated at 500 mW power dissipation on an FR-4/FR-5 board at 25 C.
What package does the SZMMSZ5237BT1G come in?
It comes in a SOD-123 surface-mount package (onsemi CASE 425-04), a compact 2-pin body suited to high-density PCB assembly, and is supplied on tape and reel for automated pick-and-place.
Is the SZMMSZ5237BT1G automotive grade?
Yes. The SZ prefix means the SZMMSZ5237BT1G is AEC-Q101 qualified and PPAP-capable, intended for automotive and other high-reliability applications, with a -65 C to +150 C junction temperature range.
What is the SZMMSZ5237BT1G used for?
It is used for shunt voltage regulation, providing a stable 8.2 V reference, and for overvoltage and transient clamping in automotive ECUs, industrial, telecom and consumer power circuits.
Is the SZMMSZ5237BT1G SMD or through-hole?
It is SMD (surface-mount) in a SOD-123 package. The through-hole 8.2 V equivalent is the axial 1N5237B in a DO-35 package.
