Product details
Overview
CRY68(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 6.8 V (min 6.2 V, max 7.4 V) at 10 mA test current, with 60 Ω typical Zener impedance, 0.7 W power dissipation, and operates across −40°C to 150°C junction temperature range - commonly used in power supply feedback loops and overvoltage protection circuits.
For engineers reviewing the CRY68(TE85L,Q,M) datasheet, CRY68(TE85L,Q,M) pinout, CRY68(TE85L,Q,M) application, or CRY68(TE85L,Q,M) equivalent, key selection criteria include verified Zener voltage tolerance, thermal derating compliance at elevated ambient temperatures, S-FLAT™ package land pattern compatibility, and reverse leakage performance under 3.0 V bias.
Technical Context
This device functions as a precision shunt regulator with stable breakdown characteristics across its operating temperature range. Its low dynamic impedance (60 Ω typ.) ensures minimal output voltage variation under load changes, while the −40°C to 150°C junction temperature rating supports industrial and automotive under-hood environments.
The CRY68(TE85L,Q,M) uses Toshiba's S-FLAT™ surface-mount package (JEITA 3-2A1S), optimized for thermal conduction on standard PCBs. Its forward voltage is ≤1.0 V at 0.2 A, and reverse leakage remains ≤10 μA at VR = 3.0 V - critical for low-power standby regulation and reference stability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 6.2–7.4 V at IZ = 10 mA - defines regulated output voltage window under nominal bias |
| Zener Impedance rd | 60 Ω typ. - determines output voltage ripple suppression capability in feedback paths |
| Power Dissipation P | 0.7 W - sets maximum continuous DC power handling before thermal derating applies |
| Junction Temperature Tj | −40°C to +150°C - enables operation in harsh environments without external heatsinking |
| Reverse Leakage IR | ≤10 μA at VR = 3.0 V - ensures low quiescent current in battery-backed or energy-sensitive circuits |
| Forward Voltage VF | ≤1.0 V at IF = 0.2 A - supports use as polarity-protected clamp or low-drop rectifier in auxiliary paths |
Pinout & Package
CRY68(TE85L,Q,M) is housed in Toshiba's S-FLAT™ surface-mount package (JEITA designation 3-2A1S), a 2-terminal, gull-wing leaded plastic package measuring 2.8 mm × 1.2 mm × 1.2 mm (L×W×H), with cathode marked by a band on the body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal during forward bias | Connected to lower-potential node in clamping or regulation path; requires proper trace width for 0.2 A surge |
| Cathode | Current exit terminal during reverse breakdown | Marked with band; ties to regulated voltage node or error amplifier input in feedback networks |
Key Features
| Feature | Design Value |
|---|---|
| Compact S-FLAT™ package | Enables high-density PCB layouts with 2.8 mm × 1.2 mm footprint and standardized 6 mm × 6 mm solder land |
| Stable Zener voltage tolerance | ±0.6 V total spread (6.2–7.4 V) ensures predictable regulation without post-production trimming |
| Low temperature coefficient | Typical αT ≈ 2.5 mV/°C (inferred from CRY62–CRZ39 family trend near 6.8 V) - minimizes drift over industrial temperature range |
| Surge absorber capability | Rated for non-repetitive peak reverse power (PRSM) up to 40 W per pulse width curves - protects downstream ICs from transient overvoltage |
Applications
| Switch-Mode Power Supply Feedback | Automotive ECU Voltage Clamp |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5234BS-7-F (Diodes Inc.) | 6.8 V nominal, 500 mW rating, SOT-323 package, 100 Ω Zz typ. | Lower power rating limits use in sustained 0.7 W dissipation; smaller package reduces thermal mass. | Select when board space is constrained and average power < 0.5 W; verify thermal relief on 6 mm² land. |
| BZX84-C6V8 (Nexperia) | 6.8 V nominal, 300 mW rating, SOT-23 package, 40 Ω Zz typ., tighter 5% Vz tolerance. | Not rated for 150°C operation; max Tj = 150°C but derated above 125°C per datasheet. | Prefer for cost-sensitive consumer designs where full industrial temp range is not required. |
Compared with MMBZ5234BS-7-F and BZX84-C6V8, the CRY68(TE85L,Q,M) offers higher power handling (0.7 W vs ≤0.5 W), wider temperature capability (−40°C to 150°C), and proven surge absorption per PRSM curves - making it suitable for industrial and automotive applications where reliability under thermal and transient stress is critical.

FAQ
What is the Zener voltage tolerance of CRY68(TE85L,Q,M) at 25°C?
The CRY68(TE85L,Q,M) has a Zener voltage range of 6.2 V (minimum) to 7.4 V (maximum) at IZ = 10 mA and Ta = 25°C, yielding a total tolerance of ±0.6 V around the nominal 6.8 V rating. This specification is confirmed in Toshiba's official CRY62–CRZ39 datasheet, page 2, Electrical Characteristics table.
Does CRY68(TE85L,Q,M) support operation at 150°C junction temperature?
Yes, CRY68(TE85L,Q,M) is rated for junction temperatures from −40°C to +150°C per Absolute Maximum Ratings (page 1). However, Toshiba recommends limiting continuous operation to Tj ≤ 120°C for high reliability, with appropriate derating applied above 25°C ambient per the thermal resistance curves in the datasheet.
What is the recommended PCB land pattern for CRY68(TE85L,Q,M)?
Toshiba specifies a 6 mm × 6 mm solder land on glass-epoxy board for optimal thermal performance (page 1, Land Pattern Dimensions). The JEITA package code is 3-2A1S, and the physical dimensions are 2.8 mm × 1.2 mm × 1.2 mm. Deviation from this land size increases junction-to-ambient thermal resistance and risks exceeding P = 0.7 W limits.
Is CRY68(TE85L,Q,M) RoHS compliant?
Toshiba confirms RoHS compliance for the CRY62–CRZ39 family, including CRY68(TE85L,Q,M), per EU Directive 2011/65/EU. Full substance declarations and test reports are available upon request through authorized Toshiba distributors or Aetrix Electronics' compliance portal.
Can CRY68(TE85L,Q,M) be used as a surge absorber in automotive applications?
Yes - the CRY68(TE85L,Q,M) is explicitly designated as a "surge absorber" in Toshiba's documentation (page 1), with non-repetitive peak reverse power (PRSM) curves supporting up to 40 W for short pulses. Its −40°C to +150°C rating and robust construction make it suitable for ISO 7637-2 transient protection in automotive ECUs and body control modules.
