Product details
Overview
SMCG36CHE3/57T from Vishay General Semiconductor is a bi-directional transient voltage suppressor (TVS) diode in DO-215AB (SMCG) package, designed for clamping voltage transients on signal/power lines. It features 36 V stand-off voltage (VWM), 1500 W peak pulse power (PPPM), 58.1 V maximum clamping voltage (VC) at 25.8 A IPPM, and AEC-Q101 qualification for automotive reliability.
For engineers reviewing the SMCG36CHE3/57T datasheet, SMCG36CHE3/57T pinout, SMCG36CHE3/57T application, or SMCG36CHE3/57T equivalent, key selection criteria include bi-directional clamping capability, 1500 W surge handling under 10/1000 µs waveform, DO-215AB surface-mount compatibility, and AEC-Q101 qualification for automotive electronics protection.
Technical Context
This bi-directional TVS operates symmetrically across both polarities, with breakdown voltage (VBR) of 40.0–44.2 V at 1 mA test current and clamps to ≤58.1 V at 25.8 A peak pulse current. Its low incremental surge resistance and fast response time enable effective suppression of ESD, lightning-induced surges, and inductive switching transients.
Thermal performance is defined by 75 °C/W junction-to-ambient thermal resistance (RθJA) on standard 8.0 mm × 8.0 mm copper pads and 15 °C/W junction-to-lead (RθJL). The device sustains operation from –55 °C to +150 °C junction temperature and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 36 V - Maximum continuous reverse operating voltage before clamping begins; defines safe working range for protected circuitry. |
| PPPM | 1500 W - Peak pulse power dissipation under 10/1000 µs waveform; determines transient energy absorption capacity. |
| VC @ IPPM | 58.1 V at 25.8 A - Clamping voltage during rated surge; directly limits stress on downstream ICs or MOSFETs. |
| VBR min/max | 40.0 / 44.2 V at 1 mA - Breakdown voltage range; ensures predictable turn-on behavior with tight manufacturing control. |
| ID @ VWM | 1.0 µA - Reverse leakage at stand-off voltage; negligible power loss and minimal impact on high-impedance signal lines. |
| TJ max. | +150 °C - Maximum junction temperature; supports under-hood automotive environments and industrial enclosures. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD robustness. |
Pinout & Package
Package: DO-215AB (SMCG) - Surface-mount gull-wing leaded package with matte tin-plated terminals, UL 94 V-0 molding compound, and no polarity marking for bi-directional operation.
| Pin/Terminal | Circuit Role | Design Meaning |

Applications
| Automotive Power Line Protection | CAN Bus Transient Suppression |
|---|---|
|
Use Scenario: Protecting 12 V battery-fed ECUs against load dump and alternator transients per ISO 7637-2. IC Role / Device Role / Timing Role: Primary clamping device placed at power entry point to limit voltage excursion to ≤58.1 V during 1500 W surges. Use Value: Prevents latch-up or permanent damage to microcontrollers and power management ICs by maintaining rail voltage within safe operating area. |

IC Role / Device Role / Timing Role: Bi-directional shunt clamp on CAN_H/CAN_L pair, responding within nanoseconds to sub-100 ns ESD events. Use Value: Maintains signal integrity by limiting common-mode voltage swing to <60 V while preserving bus timing margins and bit error rate. |
| Industrial Sensor Interface Protection | Telecom Line Card Surge Defense |
|
Use Scenario: Shielding 4–20 mA current loop transmitters and RTD/thermocouple front-ends from field wiring induced surges. IC Role / Device Role / Timing Role: Low-leakage (1.0 µA) bi-directional clamp on analog input/output paths, placed adjacent to connector entry. Use Value: Ensures measurement accuracy remains unaffected during normal operation while providing fail-safe shutdown during >1 kV transients. |
Use Scenario: Hardening Ethernet PHY interfaces and POTS line drivers in DSLAMs and base station line cards against lightning-induced surges. IC Role / Device Role / Timing Role: First-stage protector on twisted-pair ingress points, absorbing up to 1500 W before secondary TVS or GDT stages activate. Use Value: Extends system mean time between failures (MTBF) by diverting >95% of surge energy away from sensitive PHY silicon and magnetics. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ36CA | Same VWM (36 V) and bi-directionality, but lower PPPM (400 W); SMA package (DO-214AC) vs. DO-215AB. | Limited to lower-energy transients (e.g., IEC 61000-4-2 ESD only); unsuitable for ISO 7637-2 load dump. | Select SMAJ36CA only when board space allows larger SMA footprint and surge energy is <400 W. |
| 1.5KE36CA | Higher PPPM (1500 W) and same VWM, but axial-leaded DO-201AD package; not surface-mount compatible. | Requires through-hole assembly and manual rework; incompatible with automated SMT lines and compact PCBs. | Choose 1.5KE36CA only for prototyping or legacy through-hole designs where reflow compatibility is not required. |
Compared with SMCG36CHE3/57T, SMAJ36CA offers reduced surge handling and larger footprint, while 1.5KE36CA provides identical power rating but eliminates SMT manufacturability - making SMCG36CHE3/57T the optimal choice for AEC-Q101-compliant, high-density automotive and industrial SMT designs.

FAQ
What is the clamping voltage of SMCG36CHE3/57T at its rated peak pulse current?
The SMCG36CHE3/57T clamps to a maximum of 58.1 V at its rated peak pulse current (IPPM) of 25.8 A under the standard 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during surge events. The clamping performance is guaranteed across the full operating temperature range and is critical for ensuring downstream ICs remain within their absolute maximum ratings. SMCG36CHE3/57T maintains this specification with no derating required up to +125 °C ambient.
Is SMCG36CHE3/57T suitable for automotive applications?
Yes, SMCG36CHE3/57T is AEC-Q101 qualified and explicitly designed for automotive use. It undergoes rigorous stress testing including temperature cycling, highly accelerated life testing (HALT), and ESD validation per ISO 10605. Its DO-215AB package meets MSL Level 1 for lead-free reflow, and its 1500 W PPPM rating supports ISO 7637-2 Pulse 5a (load dump) protection. SMCG36CHE3/57T is deployed in engine control modules, body control units, and ADAS sensor interfaces where reliability under harsh environmental conditions is non-negotiable.
Does SMCG36CHE3/57T have polarity markings?
No, SMCG36CHE3/57T has no polarity markings because it is a bi-directional TVS diode. The device functions identically regardless of terminal orientation - both leads serve as symmetrical conduction paths during positive or negative transients. This eliminates orientation errors during automated placement and simplifies PCB layout for differential or AC-coupled signal lines. The absence of a cathode band distinguishes it from uni-directional variants like SMCG36A, which do feature a marking.
What is the thermal resistance of SMCG36CHE3/57T?
SMCG36CHE3/57T has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on the recommended 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pad per terminal, and a junction-to-lead resistance (RθJL) of 15 °C/W. These values are measured per JEDEC standards and define heat dissipation capability during repetitive surge events or sustained power dissipation. For continuous operation, the 6.5 W power rating at TA = 50 °C must be observed, and derating applies above that ambient temperature per Figure 2 in the datasheet.
How does SMCG36CHE3/57T differ from SMCG36A?
SMCG36CHE3/57T is the bi-directional, AEC-Q101 qualified variant with CA suffix and HE3 suffix, whereas SMCG36A is uni-directional (A suffix), commercial-grade (E3), and not AEC-Q101 certified. Key differences include: SMCG36CHE3/57T clamps symmetrically in both directions with no cathode band, supports automotive qualification, and uses HE3 whisker-tested leads; SMCG36A has polarity marking, lower reliability screening, and is intended for non-automotive applications. Their electrical parameters (VWM, VC, PPPM) are otherwise closely matched.
