Product details
Overview
CRZ13(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 13.0 V (min 11.7 V, max 14.3 V) at 10 mA, with 30 Ω typical Zener impedance, 0.7 W power dissipation, and operates across −40 to +150 °C junction temperature.
For engineers reviewing the CRZ13(TE85L,Q,M) datasheet, CRZ13(TE85L,Q,M) pinout, CRZ13(TE85L,Q,M) application, or CRZ13(TE85L,Q,M) equivalent, key selection criteria include its S-FLAT™ package footprint, low thermal resistance on standard PCB land patterns, stable temperature coefficient (typ. ±2.5 mV/°C), and suitability for overvoltage clamping in power supply rails and I/O protection circuits.
Technical Context
The CRZ13(TE85L,Q,M) functions as a precision shunt regulator with tight VZ tolerance (±10% at 13.0 V) and low dynamic impedance (≤30 Ω), enabling stable reference voltage generation under varying load conditions. Its silicon epitaxial construction ensures consistent breakdown characteristics and low leakage (≤10 μA at 9.0 V reverse bias).
Designed for surface-mount assembly, it uses Toshiba's proprietary S-FLAT™ package (JEITA 3-2A1S footprint), optimized for thermal performance on glass-epoxy PCBs with 6 mm × 6 mm soldering land. The device supports non-repetitive peak reverse power up to 46 W for 1 ms pulses, per PRSM–tW derating curves.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C13 (Nexperia) | Same 13 V nominal VZ, but SOT-23 package (larger footprint, higher rd = 40 Ω typ.) | Less suitable for ultra-compact layouts; higher thermal resistance limits power handling | Choose if SOT-23 is already standardized in design and 0.3 W derated power suffices |
| MMSZ5243B (ON Semiconductor) | 13 V VZ, SOD-123 package, 0.5 W rating, rd = 33 Ω typ., αT = ±3.5 mV/°C | Lower power rating reduces surge margin; wider tempco increases drift in wide-temp designs | Prefer where cost sensitivity outweighs thermal and stability requirements |
Compared with BZX84-C13 and MMSZ5243B, CRZ13(TE85L,Q,M) offers superior thermal performance in a smaller footprint, tighter VZ tolerance, and lower impedance-making it optimal for space-constrained, high-stability clamp and reference roles where 0.7 W continuous dissipation is required.

FAQ
What is the Zener voltage tolerance of CRZ13(TE85L,Q,M) at 25°C?
The CRZ13(TE85L,Q,M) has a Zener voltage range of 11.7 V (min) to 14.3 V (max) at 10 mA test current, corresponding to ±10% tolerance around the nominal 13.0 V value. This specification is verified per Toshiba's Electrical Characteristics table on page 2 of the official CRY62–CRZ39 datasheet, and applies strictly at Ta = 25°C with specified measurement conditions.
Does CRZ13(TE85L,Q,M) support bidirectional transient suppression?
Yes, CRZ13(TE85L,Q,M) can be used bidirectionally: its forward voltage is ≤1.0 V at 0.2 A, and reverse breakdown is controlled at 13.0 V. When paired with a series current-limiting resistor and optionally a companion diode, it forms a low-cost, two-quadrant TVS solution-commonly applied for I/O line protection where both positive and negative transients must be clamped.
What is the recommended PCB land pattern for CRZ13(TE85L,Q,M)?
Toshiba specifies a 6 mm × 6 mm soldering land on glass-epoxy board for optimal thermal performance. This land pattern achieves a transient thermal impedance of ~30 °C/W at 100 ms pulse width, supporting the device's 0.7 W steady-state rating. Smaller pads increase junction temperature and reduce reliability-refer to Land Pattern Dimensions on page 1 of the CRY62–CRZ39 datasheet.
Is CRZ13(TE85L,Q,M) RoHS compliant and halogen-free?
Yes, CRZ13(TE85L,Q,M) meets EU RoHS Directive 2011/65/EU requirements and is halogen-free per Toshiba's environmental compliance documentation. Full material declarations and test reports are available upon request through Aetrix Electronics' technical support team for qualifying customers.
What is the maximum non-repetitive peak reverse power (PRSM) for CRZ13(TE85L,Q,M)?
The CRZ13(TE85L,Q,M) supports a maximum non-repetitive peak reverse power (PRSM) of 46 W for a 1 ms pulse width, as defined in the PRSM–tW curve on page 4 of the CRY62–CRZ39 datasheet. This rating assumes Ta = 25°C and proper PCB thermal design; derating is required for longer pulses or elevated ambient temperatures.
