Product details
Overview
CRZ30(TE85L,Q,M) from Toshiba is a silicon epitaxial Zener diode designed for voltage regulation and surge absorption in compact SMD power management circuits, with a nominal Zener voltage of 30.0 V (min 27.0 V, max 33.0 V), 0.7 W average power dissipation, 30 Ω typical Zener impedance at 10 mA, and operating junction temperature range of −40 to 150°C. It is used in DC power rail clamping and overvoltage protection for industrial sensor interfaces.
For engineers reviewing the CRZ30(TE85L,Q,M) datasheet, CRZ30(TE85L,Q,M) pinout, CRZ30(TE85L,Q,M) application, or CRZ30(TE85L,Q,M) equivalent, key selection criteria include verified Zener voltage tolerance (±10%), thermal derating behavior up to 120°C junction, reverse leakage current ≤10 μA at 21.0 V, and compatibility with JEDEC-standard S-FLAT™ land pattern (3-2A1S).
Technical Context
This Zener diode operates in reverse-biased breakdown mode to maintain stable reference voltage under varying load and line conditions. Its 30 Ω typical dynamic impedance ensures low output voltage variation across 10 mA test current, while the −40 to 150°C junction temperature rating supports operation in thermally demanding environments without external heatsinking.
The device uses Toshiba's S-FLAT™ surface-mount package (TOSHIBA code 3-2A1S), optimized for high-density PCB layouts. Its cathode-marked anode-cathode polarity and 0.013 g mass enable automated placement and reflow compatibility, with transient thermal impedance data confirming suitability for pulsed surge suppression up to 50 W non-repetitive peak reverse power.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C30LT1G | 0.3 W power rating, SOT-23 package, 29.4–30.6 V VZ tolerance (±2%) | Lower power handling limits use to signal-level clamping; unsuitable for 0.7 W continuous dissipation | Select when tighter voltage tolerance and smaller footprint are prioritized over power robustness |
| MMBZ5257BLT1G | 0.225 W rating, SOT-23, 28.5–31.5 V VZ, 35 Ω rd | Higher dynamic impedance and lower power reduce regulation accuracy and surge margin in power rails | Prefer for low-current reference biasing where thermal rise is negligible |
Compared with CRZ30(TE85L,Q,M), BZX84-C30LT1G offers tighter voltage tolerance but only 43% of the power rating, while MMBZ5257BLT1G trades higher impedance and lower surge capacity for ultra-compact packaging - CRZ30(TE85L,Q,M) remains optimal for 0.7 W-rated industrial clamping where thermal stability and pulse robustness are critical.
