Product details
Overview
CRZ12(TE85L,Q,M) from Toshiba is a silicon epitaxial Zener diode designed for voltage regulation and surge absorption in compact surface-mount applications. It delivers a nominal Zener voltage of 12.0 V (min 10.8 V, max 13.2 V) at 10 mA, with 30 Ω typical Zener impedance, 0.7 W average power dissipation, and operates across −40 to +150 °C junction temperature range.
For engineers reviewing the CRZ12(TE85L,Q,M) datasheet, CRZ12(TE85L,Q,M) pinout, CRZ12(TE85L,Q,M) application, or CRZ12(TE85L,Q,M) equivalent, key selection criteria include Zener voltage tolerance, thermal stability (αT = ±2.5 mV/°C), low reverse leakage (≤10 μA at 8.0 V), S-FLAT™ package compatibility, and suitability for space-constrained DC rail clamping and reference circuits.
Technical Context
The CRZ12(TE85L,Q,M) functions as a precision voltage reference and transient suppressor in low-power analog and digital supply rails. Its 12 V nominal breakdown is stabilized by epitaxial construction and exhibits a temperature coefficient of ±2.5 mV/°C, enabling predictable drift behavior over industrial temperature ranges.
Designed for surface-mount assembly, it uses Toshiba's S-FLAT™ package (JEITA 3-2A1S land pattern), supports 10 mA test current, and maintains ≤30 Ω dynamic impedance - critical for maintaining regulation accuracy under varying load conditions in feedback loops and protection circuits.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C12LT1G | 12 V ±5%, 300 mW, SOT-23 package, 30 Ω rd, −65 to +150 °C | Lower power rating limits use in sustained clamp scenarios; smaller footprint reduces thermal mass | Preferred where board space is constrained and peak pulse energy is <0.1 J |
| MMBZ5242B | 12 V ±5%, 350 mW, SOT-23, 30 Ω rd, −65 to +150 °C, RoHS-compliant | Higher leakage (≤100 μA at 9.1 V) and tighter VZ tolerance reduce reference accuracy in precision circuits | Selected when cost sensitivity outweighs leakage and long-term stability requirements |
Compared with CRZ12(TE85L,Q,M), BZX84-C12LT1G offers smaller size but lower power handling, while MMBZ5242B trades leakage performance for broader availability - CRZ12(TE85L,Q,M) remains optimal for industrial-grade 0.7 W clamping with proven thermal robustness.

FAQ
What is the Zener voltage tolerance of CRZ12(TE85L,Q,M) at 25°C?
The CRZ12(TE85L,Q,M) has a Zener voltage range of 10.8 V (minimum) to 13.2 V (maximum) at 10 mA test current and 25°C ambient, corresponding to ±10% tolerance around the nominal 12.0 V rating. This specification is verified per Toshiba's Electrical Characteristics table and applies strictly under the stated test conditions.
Does CRZ12(TE85L,Q,M) support reflow soldering, and what is its maximum peak temperature?
Yes, CRZ12(TE85L,Q,M) is qualified for lead-free reflow soldering per JEDEC J-STD-020. Its S-FLAT™ package withstands a peak temperature of 260°C for up to 10 seconds. Thermal design must follow Toshiba's recommended land pattern (6 mm × 6 mm copper pad) to maintain junction temperature within −40 to +150°C limits during operation.
What is the reverse leakage current specification for CRZ12(TE85L,Q,M)?
The CRZ12(TE85L,Q,M) specifies a maximum reverse leakage current (IR) of 10 μA at 8.0 V applied reverse voltage and 25°C. This value is measured per Toshiba's Electrical Characteristics table and reflects the device's ability to minimize standby power loss in voltage reference and clamp circuits.
Is CRZ12(TE85L,Q,M) suitable for automotive applications?
CRZ12(TE85L,Q,M) meets the junction temperature range (−40 to +150°C) required for many automotive body electronics applications, such as BCM reference and LIN bus biasing. However, it is not AEC-Q200 qualified; for certified automotive use, consult Toshiba's AEC-Q200-compliant Zener portfolio or validate with full qualification testing.
How does the temperature coefficient affect CRZ12(TE85L,Q,M) in a 0–85°C operating range?
The CRZ12(TE85L,Q,M) has a typical temperature coefficient (αT) of ±2.5 mV/°C. Over a full 85°C span, this results in a maximum VZ shift of ±0.2125 V - i.e., from ~11.8 V to ~12.2 V - which is acceptable for non-critical clamping and moderate-accuracy references where absolute stability is not mandated.
