Suppressordioden, auch Transient Absorption Zener Diode (TAZ-Diode) oder Transient Voltage Suppressor Diode (TVS-Diode) genannt, sind Bauteile zum Schutz elektronischer Schaltungen vor Spannungsimpulsen. In an die Schaltung angeschlossenen Kabeln können solche Spannungspulse durch Schaltvorgänge im Netz oder nahe Blitzschläge auftreten. Die dabei kurzzeitig erreichte Spannung kann ausreichen, um Halbleiterbauelemente in der Schaltung zu zerstören. Suppressordioden werden leitend, wenn eine Spannungsschwelle überschritten wird. Der Strom des Impulses wird gefahrlos nach Masse (Elektronik) abgeleitet. Dadurch kann sich keine zerstörerische Spannung aufbauen.
Die Durchbruchspannung und der Leckstrom der Diode haben – außer bei einem Überspannungsereignis – idealerweise keinen Einfluss auf die zu schützende Schaltung. Die Strom-Spannungs-Charakteristik und der Aufbau ähneln denen einer Zenerdiode. Sie unterscheiden sich vor allem darin, dass Suppressordioden eine steilere Kennlinie bei großen Strömen besitzen. Die Spannung steigt bei sehr hohen Strömen noch weniger an als bei Zenerdioden. Sie haben gegenüber Zenerdioden ein höheres Ableitvermögen. Wie auch Zenerdioden zeichnen sich Suppressordioden durch ihre kurze Integrationszeit im Bereich von Nanosekunden aus. Zum Einsatz in Wechselspannungskreisen gibt es auch bipolare Suppressordioden, die aus gegeneinander in Reihe geschalteten Dioden bestehen, die sich unabhängig von ihrer Polung gleich verhalten.
