Product details
Overview
SMBG15CHE3/52 from Vishay General Semiconductor is a bi-directional transient voltage suppressor (TVS) diode in DO-215AA (SMBG) package, designed for clamping voltage transients on signal or power lines. It features a 15 V stand-off voltage (VWM), 16.7–18.5 V breakdown voltage (VBR) at 1 mA, 600 W peak pulse power (10/1000 μs), and clamps to ≤24.4 V at 24.6 A peak surge current - used in automotive sensor line protection per AEC-Q101 qualification.
For engineers reviewing the SMBG15CHE3/52 datasheet, SMBG15CHE3/52 pinout, SMBG15CHE3/52 application, or SMBG15CHE3/52 equivalent, key selection criteria include bi-directional clamping capability, AEC-Q101 qualification, 15 V VWM tolerance, thermal resistance (RθJA = 100 °C/W), and DO-215AA mounting compatibility with 0.2" × 0.2" copper pads.
Technical Context
This bi-directional TVS operates symmetrically in both polarities, with identical VBR min/max (16.7–18.5 V) and VC (≤24.4 V) specifications in either direction. Its glass-passivated junction ensures stable leakage (<1.0 μA at VWM) and fast response time under ESD or lightning-induced surges.
Rated for TJ = –55 °C to +150 °C operation and qualified to AEC-Q101, SMBG15CHE3/52 supports automotive-grade reliability with MSL Level 1 moisture sensitivity and matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 15 V - maximum continuous reverse operating voltage before clamping begins |
| VBR (min/max) | 16.7 V / 18.5 V at 1 mA - guaranteed breakdown threshold range defining turn-on consistency |
| VC @ IPPM | ≤24.4 V at 24.6 A - clamped voltage during 10/1000 μs surge, limiting downstream stress |
| PPPM | 600 W - peak pulse power handling per single 10/1000 μs transient event |
| ID @ VWM | ≤1.0 μA - ultra-low reverse leakage ensuring minimal standby power loss |
| RθJA | 100 °C/W - thermal resistance from junction to ambient on standard 0.2" × 0.2" copper pads |
| AEC-Q101 | Qualified - validated for automotive underhood and cabin applications requiring high-reliability surge suppression |
Pinout & Package

| MSL Level 1 (260 °C peak) | Compatible with standard lead-free reflow profiles without preconditioning or baking |
| RoHS-compliant HE3 suffix | Meets JESD 201 Class 2 whisker resistance for high-reliability solder joints in vibration-prone systems |
Applications
| Automotive Sensor Protection | Industrial CAN Bus Lines |
|---|---|
Use Scenario: Protecting ABS wheel speed sensor outputs from load-dump and ISO 7637-2 pulse 5a transients in 12 V vehicle systems. IC Role / Device Role / Timing Role: Bi-directional clamping element placed directly at connector interface to limit voltage excursions to <25 V. Use Value: Prevents damage to downstream signal conditioning ICs while maintaining signal integrity due to low capacitance and symmetric response. |
Use Scenario: Guarding CAN_H/CAN_L differential pair against ESD (IEC 61000-4-2) and burst noise in factory automation controllers. IC Role / Device Role / Timing Role: Low-capacitance TVS pair suppressing common-mode surges without distorting 1 Mbps CAN signaling edges. Use Value: Enables robust communication up to 125 m cable length by clamping transients below transceiver absolute maximum ratings. |
| Consumer USB 2.0 Data Lines | Telecom DSL Line Interface |
Use Scenario: Safeguarding USB D+/D− pins of portable media players against human-body-model ESD events during hot-plug insertion. IC Role / Device Role / Timing Role: Bi-directional TVS mounted adjacent to connector to shunt ±8 kV contact discharge energy away from PHY IC. Use Value: Maintains <1.5 pF junction capacitance to avoid signal rise-time degradation at 480 Mbps full-speed operation. |
Use Scenario: Suppressing lightning-induced surges on POTS/DSL line cards exposed to outdoor wiring in telecom central offices. IC Role / Device Role / Timing Role: Primary surge clamp on tip/ring lines ahead of hybrid transformer and line driver ICs. Use Value: Handles 600 W pulses without failure, enabling compliance with GR-1089-CORE Level 3 surge immunity requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ15CA | Same VWM (15 V), same DO-214AA package, but rated for 600 W with higher RθJA (110 °C/W) and non-AEC-Q101 qualification | Lacks automotive qualification; suitable for industrial/commercial designs where AEC-Q101 is not mandated | Select SMBJ15CA when cost optimization is prioritized and automotive reliability testing is unnecessary |
| SAC15 | Same VWM (15 V), SOD-123FL package (smaller footprint), lower PPPM (400 W), unidirectional only | Requires separate devices for bidirectional protection; limited to space-constrained consumer PCBs with lower surge exposure | Choose SAC15 only if board area is critical and surge threat level is limited to IEC 61000-4-2 ±8 kV |
Compared with SMBG15CHE3/52, SMBJ15CA offers identical electrical clamping but lacks automotive qualification and has slightly worse thermal performance, while SAC15 trades surge robustness and bidirectionality for miniaturization - making SMBG15CHE3/52 the optimal choice for AEC-Q101-compliant, high-energy transient environments.

FAQ
What is the polarity configuration of SMBG15CHE3/52?
SMBG15CHE3/52 is a bi-directional TVS diode with symmetrical terminals and no cathode marking. It provides identical clamping behavior for both positive and negative transients, making it ideal for AC-coupled or differential signal lines such as CAN bus or USB data pairs without orientation constraints during placement.
Is SMBG15CHE3/52 qualified for automotive applications?
Yes, SMBG15CHE3/52 carries the HE3 suffix indicating AEC-Q101 qualification. It has undergone rigorous stress testing including temperature cycling, humidity bias, mechanical shock, and high-temperature operating life - confirming suitability for under-hood and cabin electronics in passenger vehicles and commercial fleets.
What is the maximum clamping voltage of SMBG15CHE3/52 under surge conditions?
The maximum clamping voltage (VC) of SMBG15CHE3/52 is 24.4 V at 24.6 A peak pulse current (IPPM), measured using the standardized 10/1000 μs waveform. This value ensures protected circuits remain within safe operating limits even during worst-case transient events.
Does SMBG15CHE3/52 require special PCB layout considerations?
Yes - SMBG15CHE3/52 must be mounted on minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal to achieve rated 600 W pulse power and maintain RθJA = 100 °C/W. Short, direct traces to protected lines and ground planes are essential to minimize inductance and preserve clamping response.
How does the HE3 suffix differ from E3 in SMBG15CHE3/52?
The HE3 suffix denotes RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance, whereas E3 indicates RoHS compliance only (commercial grade). SMBG15CHE3/52's HE3 designation confirms its suitability for automotive and high-reliability industrial deployments where long-term solder joint integrity is critical.
