Product details

Overview

CRZ10(TE85L,Q) from Toshiba is a silicon epitaxial Zener diode designed for voltage regulation and surge suppression in compact SMD power management circuits. It delivers a nominal Zener voltage of 10.0 V (9.0–11.0 V range) at 10 mA, with 30 Ω typical Zener impedance, 0.7 W average power dissipation, and operates across −40 to +150 °C junction temperature. It is used in DC power rail stabilization for industrial sensors and automotive control modules.

For engineers reviewing the CRZ10(TE85L,Q) datasheet, CRZ10(TE85L,Q) pinout, CRZ10(TE85L,Q) application, or CRZ10(TE85L,Q) equivalent, key selection criteria include its 10 V regulation tolerance, low dynamic impedance, S-FLAT™ surface-mount package footprint, thermal derating guidance, and compatibility with standard PCB land pattern 3-2A1S.

Technical Context

The CRZ10(TE85L,Q) functions as a precision shunt regulator in feedback loops and overvoltage clamp circuits. Its 30 Ω typical Zener impedance ensures stable regulation under varying load currents, while its −40 to +150 °C operating junction temperature supports use in thermally demanding environments such as engine control units and industrial PLC I/O modules.

It exhibits a temperature coefficient of Zener voltage (α_T) of +6.0 mV/°C (typ.), enabling predictable drift behavior in temperature-compensated references. The device is rated for 10 μA reverse leakage at 6.0 V, confirming tight low-voltage blocking performance suitable for low-power standby circuits.

Equivalent & Alternatives

The following parts are listed as comparable options for similar Zener regulation applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BZX84-C10LT1G	0.3 W power rating, 15 Ω Zener impedance, SOT-23 package	Lower power handling limits use to sub-100 mA loads; smaller footprint reduces thermal mass	Preferred where board space is critical and peak power stays below 0.3 W

FAQ

What is the Zener voltage tolerance of CRZ10(TE85L,Q)?

The CRZ10(TE85L,Q) has a Zener voltage range of 9.0 V to 11.0 V at 10 mA test current, corresponding to ±10% tolerance around the nominal 10.0 V value. This specification is verified per Toshiba's Electrical Characteristics table on page 2 of the official datasheet. The CRZ10(TE85L,Q) achieves this tolerance using silicon epitaxial process control, ensuring consistency across production lots without post-manufacturing sorting.

Does CRZ10(TE85L,Q) support automotive temperature requirements?

Yes, CRZ10(TE85L,Q) supports automotive under-hood environments with a guaranteed junction temperature range of −40 to +150 °C.

The CRZ10(TE85L,Q) is widely deployed in body control modules and engine management subsystems where ambient temperatures exceed 105 °C.

What is the recommended PCB land pattern for CRZ10(TE85L,Q)?

Toshiba specifies land pattern 3-2A1S for CRZ10(TE85L,Q): a 6 mm × 6 mm copper pad on FR-4 board, matching the S-FLAT™ package's 2.8 mm × 1.2 mm outline. This layout ensures adequate heat dissipation to maintain the 0.7 W rating. The CRZ10(TE85L,Q) datasheet provides dimensional drawings on page 1 and thermal impedance curves on page 4 to validate thermal performance in target layouts.

How does CRZ10(TE85L,Q) perform under transient surge conditions?
