Product details
Overview
SMCJ36CA001HE3_A/I from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for high-energy surge protection with 36 V standoff voltage (VWM), 58.1 V clamping voltage (VC) at 25.8 A peak pulse current (IPPM), and 1500 W peak pulse power (PPPM). It protects sensitive signal lines and power rails in automotive ECUs and industrial sensor interfaces against lightning-induced transients and inductive switching spikes.
For engineers reviewing the SMCJ36CA001HE3_A/I datasheet, SMCJ36CA001HE3_A/I pinout, SMCJ36CA001HE3_A/I application, or SMCJ36CA001HE3_A/I equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, 1500 W surge rating, low thermal resistance (RθJL = 15 °C/W), and compatibility with automated SMT placement on standard PCB pad layouts.
Technical Context
This device operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 MΩ leakage at VWM), but triggers into low-impedance conduction when reverse (or forward, in bidirectional mode) voltage exceeds its breakdown range (40.0–44.2 V at 1 mA). Its glass-passivated junction ensures stable avalanche characteristics and fast response (<1 ns).
Designed for surface-mount use on 8.0 mm × 8.0 mm copper pads per terminal, it delivers full 1500 W pulse power handling per the 10/1000 μs waveform while maintaining junction temperature below 150 °C. The SMC package supports MSL Level 1 moisture sensitivity and lead-free soldering per J-STD-002.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 36 V - Maximum continuous reverse operating voltage before clamping begins |
| VBR min/max | 40.0 V / 44.2 V at 1 mA - Ensures reliable triggering above system nominal voltage with margin |
| VC @ IPPM | 58.1 V at 25.8 A - Clamped voltage seen by protected circuit during 1500 W transient event |
| PPPM | 1500 W - Peak surge energy absorption capacity per 10/1000 μs waveform |
| IPPM | 25.8 A - Peak current diverted during rated surge, defining minimum trace/solder joint robustness |
| TJ max | +150 °C - Maximum junction temperature enabling operation in under-hood automotive environments |
| RθJL | 15 °C/W - Low junction-to-lead thermal resistance supports efficient heat transfer to PCB copper |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, bidirectional configuration with no polarity marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (Anode) | Transient current return path | Both terminals are symmetrical; either serves as current sink during positive or negative transient events |
| Anode (Cathode) | Transient current return path | Identical function to opposite terminal; bidirectional symmetry eliminates orientation constraints during placement |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, humidity bias, and mechanical shock testing |
| 1500 W peak pulse power | Withstands ISO 7637-2 Pulse 1, 2a, 3a/b, and IEC 61000-4-5 Level 4 surges without degradation |
| Low RθJL = 15 °C/W | Enables direct thermal coupling to PCB copper, reducing need for external heatsinking in space-constrained modules |
| MSL Level 1 rating | Allows unlimited floor life and reflow at 260 °C peak, compatible with standard lead-free assembly processes |
| Glass-passivated junction | Provides stable, repeatable breakdown voltage over lifetime and across temperature (-55 °C to +150 °C) |
Applications
| Automotive Power Supply Protection | Industrial Sensor Signal Line Protection |
|---|---|
Use Scenario: Protecting 12 V battery-fed microcontroller power rails in engine control units exposed to load dump and alternator ripple. IC Role / Device Role / Timing Role: Shunt TVS device clamping transients before they reach LDO regulators and MCU VCC pins. Use Value: Limits voltage excursion to ≤58.1 V during 1500 W surges, preventing latch-up or gate oxide damage in downstream ICs. | Use Scenario: Safeguarding 4–20 mA current loop inputs of PLC analog input modules against ESD and field wiring faults. IC Role / Device Role / Timing Role: Bidirectional voltage clamp placed across signal and return lines to divert ±2 kV contact ESD per IEC 61000-4-2. Use Value: Symmetric clamping ensures protection regardless of fault polarity, preserving signal integrity without adding series impedance. |
| Telecom DC Power Feeds | Consumer Appliance Motor Drive Circuits |
Use Scenario: Guarding PoE-powered Ethernet switch ports against induced surges from nearby AC mains or lightning coupling. IC Role / Device Role / Timing Role: Primary-level TVS on 48 V DC feed lines upstream of DC-DC converters and PHY ICs. Use Value: 36 V VWM allows safe operation at nominal 48 V with headroom; 58.1 V VC stays below 60 V absolute maximum ratings of most PoE interface ICs. | Use Scenario: Suppressing commutation spikes from brushed DC motors in smart home appliances (e.g., vacuum cleaners, blenders). IC Role / Device Role / Timing Role: Across-motor terminals to clamp inductive kickback during MOSFET turn-off. Use Value: 1500 W rating handles repetitive 100–200 mJ spikes without parametric shift, extending motor driver lifespan. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAC36CA-E3/57T | Same VWM (36 V), lower PPPM (600 W), smaller SMA package | Lower surge capacity; suitable only for consumer-grade, non-automotive applications | Select when board space is critical and surge threat level is limited to IEC 61000-4-2 Level 2 |
| 1.5KE36CA | Same VWM (36 V), same PPPM (1500 W), axial DO-201 package | Through-hole mounting; incompatible with automated SMT lines and high-density layouts | Choose only for legacy through-hole designs or prototyping where rework tolerance is prioritized over production efficiency |
Compared with SAC36CA-E3/57T and 1.5KE36CA, the SMCJ36CA001HE3_A/I uniquely combines AEC-Q101 qualification, SMC surface-mount form factor, and full 1500 W rating-making it the only option qualified for volume automotive production with automated assembly and high-reliability field deployment.

FAQ
What does the 'CA' suffix indicate in SMCJ36CA001HE3_A/I?
The 'CA' suffix denotes a bidirectional configuration: SMCJ36CA001HE3_A/I provides symmetrical clamping for both positive and negative transients, unlike unidirectional variants (e.g., SMCJ36A) that clamp only in reverse bias. This makes the SMCJ36CA001HE3_A/I ideal for AC-coupled signal lines or differential buses where polarity of surge events is unpredictable.
Is SMCJ36CA001HE3_A/I qualified for automotive use?
Yes, SMCJ36CA001HE3_A/I carries the HE3 suffix, confirming it is RoHS-compliant and AEC-Q101 qualified. This certification covers stress tests including temperature cycling, high-temperature operating life, and ESD robustness-ensuring suitability for under-hood and body-control module applications per automotive OEM requirements.
What is the clamping voltage of SMCJ36CA001HE3_A/I at its rated peak pulse current?
The clamping voltage (VC) of SMCJ36CA001HE3_A/I is 58.1 V at its rated peak pulse current (IPPM) of 25.8 A, measured using the standardized 10/1000 μs double-exponential waveform. This value defines the maximum voltage imposed on protected circuitry during a full 1500 W transient event.
How does the SMC (DO-214AB) package of SMCJ36CA001HE3_A/I affect thermal performance?
The SMC package of SMCJ36CA001HE3_A/I delivers a typical junction-to-lead thermal resistance (RθJL) of 15 °C/W, enabling efficient heat transfer to PCB copper pads. When mounted on the recommended 8.0 mm × 8.0 mm copper areas per terminal, this allows sustained power dissipation without exceeding the +150 °C maximum junction temperature under surge conditions.
Can SMCJ36CA001HE3_A/I replace older SMCJ36CA variants in existing designs?
Yes, SMCJ36CA001HE3_A/I maintains identical electrical specifications, package dimensions, and pinout as prior SMCJ36CA revisions. The '001' denotes a specific manufacturing revision, and the HE3 suffix confirms AEC-Q101 qualification-so it can be used as a drop-in replacement in any design previously using SMCJ36CA-E3 or SMCJ36CA-M3, with added assurance of automotive-grade reliability.
