Product details
Overview
TPSMC30HE3_A/H from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for high-energy surge protection on power and signal lines. It features a 30 V breakdown voltage (VBR = 28.5–31.5 V at 1 mA), 25.6 V stand-off voltage (VWM), 41.4 V clamping voltage (VC) at 36.2 A peak pulse current, 1500 W peak pulse power (10/1000 μs), and operates up to +185 °C junction temperature - ideal for automotive power rail protection.
For engineers reviewing the TPSMC30HE3_A/H datasheet, TPSMC30HE3_A/H pinout, TPSMC30HE3_A/H application, or TPSMC30HE3_A/H equivalent, key selection criteria include clamping performance under 10/1000 μs transients, AEC-Q101 qualification status, unidirectional polarity, thermal derating above 25 °C, and compatibility with automated SMT assembly using J-STD-002-compliant matte tin terminals.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology optimized for low incremental surge resistance and fast response time (<1 ns), enabling effective suppression of ESD and lightning-induced transients. Its junction passivation and 185 °C maximum operating temperature support high-reliability deployment in under-hood automotive environments and industrial motor drive control circuits.
The device is rated for non-repetitive 200 A forward surge current (8.3 ms half-sine) and exhibits stable VBR temperature coefficient (αT = 0.088 %/°C), allowing predictable clamping behavior across wide ambient ranges. It meets MSL Level 1 per J-STD-020 and is RoHS-compliant with halogen-free option available via HM3 suffix.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 28.5 / 30.0 / 31.5 V at 1 mA - defines precise voltage threshold where avalanche conduction begins, critical for coordination with downstream IC overvoltage limits |
| VWM | 25.6 V - maximum continuous reverse working voltage; must exceed system nominal voltage to prevent leakage during normal operation |
| VC @ IPPM | 41.4 V at 36.2 A - clamped voltage during 10/1000 μs surge; determines worst-case stress on protected circuitry |
| PPPM | 1500 W - peak pulse power handling capability; sets upper bound for transient energy absorption without failure |
| TJ max. | +185 °C - enables use in high-temperature zones such as engine control units and power converters without thermal derating penalties |
| Polarity | Unidirectional - protects against positive-going transients only; requires external design consideration for bidirectional threats |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, molded case meeting UL 94 V-0 flammability rating; cathode indicated by color band; matte tin-plated leads solderable per J-STD-002.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Transient current sink node | Connected to protected line; conducts surge current to ground when VLINE exceeds VBR |
| Anode | Reference/ground return path | Typically tied to system ground plane; completes conduction path during clamping event |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and surge endurance - required for powertrain and body electronics |
| 1500 W peak pulse power (10/1000 μs) | Supports IEC 61000-4-5 Level 4 (4 kV) surge immunity without cascaded protection stages |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients, improving protection margin for 3.3 V/5 V logic interfaces |
| Junction temperature capability up to +185 °C | Enables placement near heat sources (e.g., MOSFETs, inductors) without thermal shutdown or parameter drift |
Applications
| Automotive Power Rail Protection | Industrial Motor Drive Control |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs from load dump and alternator ripple transients in passenger vehicles. IC Role / Device Role / Timing Role: Primary clamping element placed between battery input and DC-DC converter input stage. Use Value: Clamps 12 V rail to ≤41.4 V during 10/1000 μs surges, preventing damage to downstream 40 V-rated regulators and microcontrollers. | Use Scenario: Safeguarding gate driver inputs and feedback sensing lines in variable-frequency AC drives. IC Role / Device Role / Timing Role: Transient shunt on isolated signal paths carrying PWM timing or current sense data. Use Value: Sub-1 ns response ensures clamping occurs before transient propagates into optocoupler or digital isolator inputs. |
| Telecom Power Interface | Consumer Appliance Mainboard |
Use Scenario: Input-stage protection on PoE-powered network switches and base stations. IC Role / Device Role / Timing Role: First-line defense against induced surges on 48 V DC input rails. Use Value: Withstands repeated 1500 W pulses while maintaining VWM = 25.6 V - compatible with 48 V nominal systems using 30 V intermediate regulation. | Use Scenario: Overvoltage suppression on mainboard 24 V auxiliary supply feeding display backlight and fan controllers. IC Role / Device Role / Timing Role: Standoff-rated TVS placed directly at connector entry point. Use Value: 25.6 V VWM avoids leakage at 24 V nominal, while 41.4 V VC stays below absolute maximum ratings of connected LDOs and drivers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ30A | Lower PPPM (600 W), same VBR range, SMB package (smaller footprint, lower thermal mass) | Limited to lower-energy transients; unsuitable for automotive load dump per ISO 7637-2 Pulse 5a | Select when space-constrained and surge energy < 100 mJ; verify thermal dissipation in PCB layout |
| TPSMC33AHE3_A/H | Higher VBR (31.4–34.7 V), VWM = 28.2 V, identical package and AEC-Q101 qualification | Better suited for 24 V systems with higher tolerance margins; slightly reduced clamping ratio | Choose for 24 V nominal rails requiring tighter coordination with 36 V-rated components |
Compared with SMBJ30A and TPSMC33AHE3_A/H, the TPSMC30HE3_A/H offers optimal balance of 1500 W surge capacity, 25.6 V standoff, and automotive qualification - making it preferred for 12 V battery-supplied modules where both energy handling and thermal robustness are critical.

FAQ
What is the clamping voltage of the TPSMC30HE3_A/H under standard test conditions?
The TPSMC30HE3_A/H has a maximum clamping voltage (VC) of 41.4 V at 36.2 A peak pulse current (IPPM) using a 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and represents the upper voltage limit imposed on protected circuitry during a standardized surge event. The TPSMC30HE3_A/H maintains this clamping performance across its full operating temperature range due to its stable temperature coefficient.
Is the TPSMC30HE3_A/H qualified for automotive applications?
Yes, the TPSMC30HE3_A/H is AEC-Q101 qualified, as confirmed by Vishay's documentation and ordering code suffix HE3. It undergoes rigorous stress testing including high-temperature reverse bias, temperature cycling, and surge endurance - making it suitable for under-hood and chassis-mounted automotive modules. The TPSMC30HE3_A/H also supports MSL Level 1 handling and lead-free reflow up to 260 °C peak.
What does the "HE3" suffix indicate in TPSMC30HE3_A/H?
The "HE3" suffix in TPSMC30HE3_A/H denotes RoHS-compliant construction with AEC-Q101 qualification and matte tin-plated leads compliant with J-STD-002. The "_A/H" portion specifies revision A and packaging in 7-inch tape-and-reel (H = 850 units per reel). This distinguishes it from HM3 variants (halogen-free) and non-automotive versions lacking the HE3 designation.
Can the TPSMC30HE3_A/H be used in bidirectional protection configurations?
No, the TPSMC30HE3_A/H is unidirectional only, as explicitly stated in the Vishay datasheet. It conducts surge current from cathode to anode only and cannot suppress negative-going transients. For bidirectional protection, two TPSMC30HE3_A/H devices must be connected in series opposition, or a dedicated bidirectional TVS such as SMAJ30A should be selected instead.
What is the maximum junction temperature rating for the TPSMC30HE3_A/H?
The TPSMC30HE3_A/H is rated for a maximum junction temperature (TJ) of +185 °C, verified per Vishay's thermal characterization and AEC-Q101 test requirements. This allows reliable operation in high-ambient environments such as engine control units and industrial inverters. Derating curves in the datasheet show pulse power reduction above 25 °C ambient, and the TPSMC30HE3_A/H maintains full 1500 W rating only at TJ ≤ 25 °C.
