Spice model di DIAC che non funziona

Salve uso switchercadIII per le simulazioni, il modello che uso per il diac e' molto scadente ed e' questo (conduce un po' quando vuole):

*Generic DIAC .subckt DIAC T1 T2

• default parameters .param RS=10 ; series resistance .param VK=20 ; breakdown voltage Q1 N002 N001 T2 0 PN Q2 N001 N002 N005 0 NP R1 N002 N004 {20K*(VK-1)} R2 N004 T2 9.5K R3 N002 N005 9.5K Q3 N004 N003 N005 0 PN Q4 N003 N004 T2 0 NP R4 T1 N005 {RS} .model PN NPN Cjc=10p Cje=10p .model NP PNP Cjc=10p Cje=10p .ends DIAC

In rete ho trovato questi due che pero' non funzionano, sono per LTspice e credo siano adatti, noto che il comando .subckt ha parametri diversi pur es sendo in tutti i casi un diac, io non mi ci raccapezzo, qualcuno conosce le modifiche da fare per farlo funzionare? Nel secondo mi pare di capire che sono compresi 6 modelli, ma per usarli de vo rinominare il componente sullo schema chiamandolo non "diac" ma "db3"?

Grazie
